      The 'zlib' compression library provides in-memory compression and
   decompression functions, including integrity checks of the uncompressed
   data.  This version of the library supports only one compression method
   (deflation) but other algorithms will be added later and will have the same
   stream interface.
 
      Compression can be done in a single step if the buffers are large
   enough (for example if an input file is mmap'ed), or can be done by
   repeated calls of the compression function.  In the latter case, the
   application must provide more input and/or consume the output
   (providing more output space) before each call.
 
      The library also supports reading and writing files in gzip (.gz) format
   with an interface similar to that of stdio.
 
      The library does not install any signal handler. The decoder checks
   the consistency of the compressed data, so the library should never
   crash even in case of corrupted input.
 */
 
 /*
    The application must update next_in and avail_in when avail_in has
    dropped to zero. It must update next_out and avail_out when avail_out
    has dropped to zero. The application must initialize zalloc, zfree and
    opaque before calling the init function. All other fields are set by the
    compression library and must not be updated by the application.
 
    The opaque value provided by the application will be passed as the first
    parameter for calls of zalloc and zfree. This can be useful for custom
    memory management. The compression library attaches no meaning to the
    opaque value.
 
    zalloc must return Z_NULL if there is not enough memory for the object.
    If zlib is used in a multi-threaded application, zalloc and zfree must be
    thread safe.
 
    On 16-bit systems, the functions zalloc and zfree must be able to allocate
    exactly 65536 bytes, but will not be required to allocate more than this
    if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,
    pointers returned by zalloc for objects of exactly 65536 bytes *must*
    have their offset normalized to zero. The default allocation function
    provided by this library ensures this (see zutil.c). To reduce memory
    requirements and avoid any allocation of 64K objects, at the expense of
    compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).
 
    The fields total_in and total_out can be used for statistics or
    progress reports. After compression, total_in holds the total size of
    the uncompressed data and may be saved for use in the decompressor
    (particularly if the decompressor wants to decompress everything in
    a single step).

 /*
     deflate compresses as much data as possible, and stops when the input
   buffer becomes empty or the output buffer becomes full. It may introduce some
   output latency (reading input without producing any output) except when
   forced to flush.
 
     The detailed semantics are as follows. deflate performs one or both of the
   following actions:
 
   - Compress more input starting at next_in and update next_in and avail_in
     accordingly. If not all input can be processed (because there is not
     enough room in the output buffer), next_in and avail_in are updated and
     processing will resume at this point for the next call of deflate().
 
   - Provide more output starting at next_out and update next_out and avail_out
     accordingly. This action is forced if the parameter flush is non zero.
     Forcing flush frequently degrades the compression ratio, so this parameter
     should be set only when necessary (in interactive applications).
     Some output may be provided even if flush is not set.
 
   Before the call of deflate(), the application should ensure that at least
   one of the actions is possible, by providing more input and/or consuming
   more output, and updating avail_in or avail_out accordingly; avail_out
   should never be zero before the call. The application can consume the
   compressed output when it wants, for example when the output buffer is full
   (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
   and with zero avail_out, it must be called again after making room in the
   output buffer because there might be more output pending.
 
     If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
   flushed to the output buffer and the output is aligned on a byte boundary, so
   that the decompressor can get all input data available so far. (In particular
   avail_in is zero after the call if enough output space has been provided
   before the call.)  Flushing may degrade compression for some compression
   algorithms and so it should be used only when necessary.
 
     If flush is set to Z_FULL_FLUSH, all output is flushed as with
   Z_SYNC_FLUSH, and the compression state is reset so that decompression can
   restart from this point if previous compressed data has been damaged or if
   random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
   the compression.
 
     If deflate returns with avail_out == 0, this function must be called again
   with the same value of the flush parameter and more output space (updated
   avail_out), until the flush is complete (deflate returns with non-zero
   avail_out).
 
     If the parameter flush is set to Z_FINISH, pending input is processed,
   pending output is flushed and deflate returns with Z_STREAM_END if there
   was enough output space; if deflate returns with Z_OK, this function must be
   called again with Z_FINISH and more output space (updated avail_out) but no
   more input data, until it returns with Z_STREAM_END or an error. After
   deflate has returned Z_STREAM_END, the only possible operations on the
   stream are deflateReset or deflateEnd.
   
     Z_FINISH can be used immediately after deflateInit if all the compression
   is to be done in a single step. In this case, avail_out must be at least
   0.1% larger than avail_in plus 12 bytes.  If deflate does not return
   Z_STREAM_END, then it must be called again as described above.
 
     deflate() sets strm->adler to the adler32 checksum of all input read
   so (that is, total_in bytes).
 
     deflate() may update data_type if it can make a good guess about
   the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
   binary. This field is only for information purposes and does not affect
   the compression algorithm in any manner.
 
     deflate() returns Z_OK if some progress has been made (more input
   processed or more output produced), Z_STREAM_END if all input has been
   consumed and all output has been produced (only when flush is set to
   Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
   if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible
   (for example avail_in or avail_out was zero).

      deflateEnd returns Z_OK if success, Z_STREAM_ERROR if the
    stream state was inconsistent, Z_DATA_ERROR if the stream was freed

 int inflateInit OF((z_streamp strm));

    value depends on the compression method), inflateInit determines the
    compression method from the zlib header and allocates all data structures
    accordingly; otherwise the allocation will be deferred to the first call of
    inflate.  If zalloc and zfree are set to Z_NULL, inflateInit updates them to
    use default allocation functions.
 
      inflateInit returns Z_OK if success, Z_MEM_ERROR if there was not enough

 static int inflate OF((z_streamp strm, int flush));
 /*
     inflate decompresses as much data as possible, and stops when the input
   buffer becomes empty or the output buffer becomes full. It may some
   introduce some output latency (reading input without producing any output)
   except when forced to flush.
 
   The detailed semantics are as follows. inflate performs one or both of the
   following actions:
 
   - Decompress more input starting at next_in and update next_in and avail_in
     accordingly. If not all input can be processed (because there is not
     enough room in the output buffer), next_in is updated and processing
     will resume at this point for the next call of inflate().
 
   - Provide more output starting at next_out and update next_out and avail_out
     accordingly.  inflate() provides as much output as possible, until there
     is no more input data or no more space in the output buffer (see below
     about the flush parameter).
 
   Before the call of inflate(), the application should ensure that at least
   one of the actions is possible, by providing more input and/or consuming
   more output, and updating the next_* and avail_* values accordingly.
   The application can consume the uncompressed output when it wants, for
   example when the output buffer is full (avail_out == 0), or after each
   call of inflate(). If inflate returns Z_OK and with zero avail_out, it
   must be called again after making room in the output buffer because there
   might be more output pending.
 
     If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
   output as possible to the output buffer. The flushing behavior of inflate is
   not specified for values of the flush parameter other than Z_SYNC_FLUSH
   and Z_FINISH, but the current implementation actually flushes as much output
   as possible anyway.
 
     inflate() should normally be called until it returns Z_STREAM_END or an
   error. However if all decompression is to be performed in a single step
   (a single call of inflate), the parameter flush should be set to
   Z_FINISH. In this case all pending input is processed and all pending
   output is flushed; avail_out must be large enough to hold all the
   uncompressed data. (The size of the uncompressed data may have been saved
   by the compressor for this purpose.) The next operation on this stream must
   be inflateEnd to deallocate the decompression state. The use of Z_FINISH
   is never required, but can be used to inform inflate that a faster routine
   may be used for the single inflate() call.
 
      If a preset dictionary is needed at this point (see inflateSetDictionary
   below), inflate sets strm-adler to the adler32 checksum of the
   dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise 
   it sets strm->adler to the adler32 checksum of all output produced
   so (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
   an error code as described below. At the end of the stream, inflate()
   checks that its computed adler32 checksum is equal to that saved by the
   compressor and returns Z_STREAM_END only if the checksum is correct.
 
     inflate() returns Z_OK if some progress has been made (more input processed
   or more output produced), Z_STREAM_END if the end of the compressed data has
   been reached and all uncompressed output has been produced, Z_NEED_DICT if a
   preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
   corrupted (input stream not conforming to the zlib format or incorrect
   adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent
   (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not
   enough memory, Z_BUF_ERROR if no progress is possible or if there was not
   enough room in the output buffer when Z_FINISH is used. In the Z_DATA_ERROR
   case, the application may then call inflateSync to look for a good
   compression block.

      This is another version of deflateInit with more compression options. The
    fields next_in, zalloc, zfree and opaque must be initialized before by
    the caller.
 
      The method parameter is the compression method. It must be Z_DEFLATED in
    this version of the library.
 
      The windowBits parameter is the base two logarithm of the window size
    (the size of the history buffer).  It should be in the range 8..15 for this
    version of the library. Larger values of this parameter result in better
    compression at the expense of memory usage. The default value is 15 if
    deflateInit is used instead.
 
      The memLevel parameter specifies how much memory should be allocated
    for the internal compression state. memLevel=1 uses minimum memory but
    is slow and reduces compression ratio; memLevel=9 uses maximum memory
    for optimal speed. The default value is 8. See zconf.h for total memory
    usage as a function of windowBits and memLevel.
 
      The strategy parameter is used to tune the compression algorithm. Use the
    value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
    filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
    string match).  Filtered data consists mostly of small values with a
    somewhat random distribution. In this case, the compression algorithm is
    tuned to compress them better. The effect of Z_FILTERED is to force more
    Huffman coding and less string matching; it is somewhat intermediate
    between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
    the compression ratio but not the correctness of the compressed output even
    if it is not set appropriately.
 
       deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
    memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid
    method). msg is set to null if there is no error message.  deflateInit2 does
    not perform any compression: this will be done by deflate().

 /*
      Initializes the compression dictionary from the given byte sequence
    without producing any compressed output. This function must be called
    immediately after deflateInit, deflateInit2 or deflateReset, before any
    call of deflate. The compressor and decompressor must use exactly the same
    dictionary (see inflateSetDictionary).
 
      The dictionary should consist of strings (byte sequences) that are likely
    to be encountered later in the data to be compressed, with the most commonly
    used strings preferably put towards the end of the dictionary. Using a
    dictionary is most useful when the data to be compressed is short and can be
    predicted with good accuracy; the data can then be compressed better than
    with the default empty dictionary.
 
      Depending on the size of the compression data structures selected by
    deflateInit or deflateInit2, a part of the dictionary may in effect be
    discarded, for example if the dictionary is larger than the window size in
    deflate or deflate2. Thus the strings most likely to be useful should be
    put at the end of the dictionary, not at the front.
 
      Upon return of this function, strm->adler is set to the Adler32 value
    of the dictionary; the decompressor may later use this value to determine
    which dictionary has been used by the compressor. (The Adler32 value
    applies to the whole dictionary even if only a subset of the dictionary is
    actually used by the compressor.)
 
      deflateSetDictionary returns Z_OK if success, or Z_STREAM_ERROR if a
    parameter is invalid (such as NULL dictionary) or the stream state is
    inconsistent (for example if deflate has already been called for this stream
    or if the compression method is bsort). deflateSetDictionary does not
    perform any compression: this will be done by deflate().

 /*
    Notes beyond the 1.93a appnote.txt:
 
    1. Distance pointers never point before the beginning of the output
       stream.
    2. Distance pointers can point back across blocks, up to 32k away.
    3. There is an implied maximum of 7 bits for the bit length table and
       15 bits for the actual data.
    4. If only one code exists, then it is encoded using one bit.  (Zero
       would be more efficient, but perhaps a little confusing.)  If two
       codes exist, they are coded using one bit each (0 and 1).
    5. There is no way of sending zero distance codes--a dummy must be
       sent if there are none.  (History: a pre 2.0 version of PKZIP would
       store blocks with no distance codes, but this was discovered to be
       too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
       zero distance codes, which is sent as one code of zero bits in
       length.
    6. There are up to 286 literal/length codes.  Code 256 represents the
       end-of-block.  Note however that the static length tree defines
       288 codes just to fill out the Huffman codes.  Codes 286 and 287
       cannot be used though, since there is no length base or extra bits
       defined for them.  Similarily, there are up to 30 distance codes.
       However, static trees define 32 codes (all 5 bits) to fill out the
       Huffman codes, but the last two had better not show up in the data.
    7. Unzip can check dynamic Huffman blocks for complete code sets.
       The exception is that a single code would not be complete (see #4).
    8. The five bits following the block type is really the number of
       literal codes sent minus 257.
    9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
       (1+6+6).  Therefore, to output three times the length, you output
       three codes (1+1+1), whereas to output four times the same length,
       you only need two codes (1+3).  Hmm.
   10. In the tree reconstruction algorithm, Code = Code + Increment
       only if BitLength(i) is not zero.  (Pretty obvious.)
   11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
   12. Note: length code 284 can represent 227-258, but length code 285
       really is 258.  The last length deserves its own, short code
       since it gets used a lot in very redundant files.  The length
       258 is special since 258 - 3 (the min match length) is 255.
   13. The literal/length and distance code bit lengths are read as a
       single stream of lengths.  It is possible (and advantageous) for
       a repeat code (16, 17, or 18) to go across the boundary between
       the two sets of lengths.

 /*
    Huffman code decoding is performed using a multi-level table lookup.
    The fastest way to decode is to simply build a lookup table whose
    size is determined by the longest code.  However, the time it takes
    to build this table can also be a factor if the data being decoded
    is not very long.  The most common codes are necessarily the
    shortest codes, so those codes dominate the decoding time, and hence
    the speed.  The idea is you can have a shorter table that decodes the
    shorter, more probable codes, and then point to subsidiary tables for
    the longer codes.  The time it costs to decode the longer codes is
    then traded against the time it takes to make longer tables.
 
    This results of this trade are in the variables lbits and dbits
    below.  lbits is the number of bits the first level table for literal/
    length codes can decode in one step, and dbits is the same thing for
    the distance codes.  Subsequent tables are also less than or equal to
    those sizes.  These values may be adjusted either when all of the
    codes are shorter than that, in which case the longest code length in
    bits is used, or when the shortest code is *longer* than the requested
    table size, in which case the length of the shortest code in bits is
    used.
 
    There are two different values for the two tables, since they code a
    different number of possibilities each.  The literal/length table
    codes 286 possible values, or in a flat code, a little over eight
    bits.  The distance table codes 30 possible values, or a little less
    than five bits, flat.  The optimum values for speed end up being
    about one bit more than those, so lbits is 8+1 and dbits is 5+1.
    The optimum values may differ though from machine to machine, and
    possibly even between compilers.  Your mileage may vary.
