     Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951:
     http://www.ietf.org/rfc/rfc1951.txt
  
     Most API's defined in miniz.c are optional. For example, to disable the
     archive related functions just define
     MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO
     (see the list below for more macros).
  
     * Change History
       10/13/13 v1.15 r4 - Interim bugfix release while I work on the next major
     release with Zip64 support (almost there!):
         - Critical fix for the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug
     (thanks kahmyong.moon@hp.com) which could cause locate files to not find
     files. This bug
          would only have occured in earlier versions if you explicitly used this
     flag, OR if you used mz_zip_extract_archive_file_to_heap() or
     mz_zip_add_mem_to_archive_file_in_place()
          (which used this flag). If you can't switch to v1.15 but want to fix
     this bug, just remove the uses of this flag from both helper funcs (and of
     course don't use the flag).
         - Bugfix in mz_zip_reader_extract_to_mem_no_alloc() from kymoon when
     pUser_read_buf is not NULL and compressed size is > uncompressed size
         - Fixing mz_zip_reader_extract_*() funcs so they don't try to extract
     compressed data from directory entries, to account for weird zipfiles which
     contain zero-size compressed data on dir entries.
           Hopefully this fix won't cause any issues on weird zip archives,
     because it assumes the low 16-bits of zip external attributes are DOS
     attributes (which I believe they always are in practice).
         - Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the
     internal attributes, just the filename and external attributes
         - mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed
         - Added cmake support for Linux builds which builds all the examples,
     tested with clang v3.3 and gcc v4.6.
         - Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti
         - Merged MZ_FORCEINLINE fix from hdeanclark
         - Fix <time.h> include before config #ifdef, thanks emil.brink
         - Added tdefl_write_image_to_png_file_in_memory_ex(): supports Y flipping
     (super useful for OpenGL apps), and explicit control over the compression
     level (so you can
          set it to 1 for real-time compression).
         - Merged in some compiler fixes from paulharris's github repro.
         - Retested this build under Windows (VS 2010, including static analysis),
     tcc  0.9.26, gcc v4.6 and clang v3.3.
         - Added example6.c, which dumps an image of the mandelbrot set to a PNG
     file.
         - Modified example2 to help test the
     MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more.
         - In r3: Bugfix to mz_zip_writer_add_file() found during merge: Fix
     possible src file fclose() leak if alignment bytes+local header file write
     faiiled
                   - In r4: Minor bugfix to mz_zip_writer_add_from_zip_reader():
     Was pushing the wrong central dir header offset, appears harmless in this
     release, but it became a problem in the zip64 branch
       5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE,
     #include <time.h> (thanks fermtect).
       5/19/12 v1.13 - From jason@cornsyrup.org and kelwert@mtu.edu - Fix
     mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit.
         - Temporarily/locally slammed in "typedef unsigned long mz_ulong" and
     re-ran a randomized regression test on ~500k files.
         - Eliminated a bunch of warnings when compiling with GCC 32-bit/64.
         - Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze
     (static analysis) option and fixed all warnings (except for the silly
          "Use of the comma-operator in a tested expression.." analysis warning,
     which I purposely use to work around a MSVC compiler warning).
         - Created 32-bit and 64-bit Codeblocks projects/workspace. Built and
     tested Linux executables. The codeblocks workspace is compatible with
     Linux+Win32/x64.
         - Added miniz_tester solution/project, which is a useful little app
     derived from LZHAM's tester app that I use as part of the regression test.
         - Ran miniz.c and tinfl.c through another series of regression testing on
     ~500,000 files and archives.
         - Modified example5.c so it purposely disables a bunch of high-level
     functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the
     MINIZ_NO_STDIO bug report.)
         - Fix ftell() usage in examples so they exit with an error on files which
     are too large (a limitation of the examples, not miniz itself).
       4/12/12 v1.12 - More comments, added low-level example5.c, fixed a couple
     minor level_and_flags issues in the archive API's.
        level_and_flags can now be set to MZ_DEFAULT_COMPRESSION. Thanks to Bruce
     Dawson <bruced@valvesoftware.com> for the feedback/bug report.
       5/28/11 v1.11 - Added statement from unlicense.org
       5/27/11 v1.10 - Substantial compressor optimizations:
        - Level 1 is now ~4x faster than before. The L1 compressor's throughput
     now varies between 70-110MB/sec. on a
        - Core i7 (actual throughput varies depending on the type of data, and x64
     vs. x86).
        - Improved baseline L2-L9 compression perf. Also, greatly improved
     compression perf. issues on some file types.
        - Refactored the compression code for better readability and
     maintainability.
        - Added level 10 compression level (L10 has slightly better ratio than
     level 9, but could have a potentially large
         drop in throughput on some files).
       5/15/11 v1.09 - Initial stable release.
  
     * Low-level Deflate/Inflate implementation notes:
  
       Compression: Use the "tdefl" API's. The compressor supports raw, static,
     and dynamic blocks, lazy or
       greedy parsing, match length filtering, RLE-only, and Huffman-only streams.
     It performs and compresses
       approximately as well as zlib.
  
       Decompression: Use the "tinfl" API's. The entire decompressor is
     implemented as a single function
       coroutine: see tinfl_decompress(). It supports decompression into a 32KB
     (or larger power of 2) wrapping buffer, or into a memory
       block large enough to hold the entire file.
  
       The low-level tdefl/tinfl API's do not make any use of dynamic memory
     allocation.
  
     * zlib-style API notes:
  
       miniz.c implements a fairly large subset of zlib. There's enough
     functionality present for it to be a drop-in
       zlib replacement in many apps:
          The z_stream struct, optional memory allocation callbacks
          deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
          inflateInit/inflateInit2/inflate/inflateEnd
          compress, compress2, compressBound, uncompress
          CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly
     routines.
          Supports raw deflate streams or standard zlib streams with adler-32
     checking.
  
       Limitations:
        The callback API's are not implemented yet. No support for gzip headers or
     zlib static dictionaries.
        I've tried to closely emulate zlib's various flavors of stream flushing
     and return status codes, but
        there are no guarantees that miniz.c pulls this off perfectly.
  
     * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function,
     originally written by
       Alex Evans. Supports 1-4 bytes/pixel images.
  
     * ZIP archive API notes:
  
       The ZIP archive API's where designed with simplicity and efficiency in
     mind, with just enough abstraction to
       get the job done with minimal fuss. There are simple API's to retrieve file
     information, read files from
       existing archives, create new archives, append new files to existing
     archives, or clone archive data from
       one archive to another. It supports archives located in memory or the heap,
     on disk (using stdio.h),
       or you can specify custom file read/write callbacks.
  
       - Archive reading: Just call this function to read a single file from a
     disk archive:
  
        void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const
     char *pArchive_name,
          size_t *pSize, mz_uint zip_flags);
  
       For more complex cases, use the "mz_zip_reader" functions. Upon opening an
     archive, the entire central
       directory is located and read as-is into memory, and subsequent file access
     only occurs when reading individual files.
  
       - Archives file scanning: The simple way is to use this function to scan a
     loaded archive for a specific file:
  
       int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName,
     const char *pComment, mz_uint flags);
  
       The locate operation can optionally check file comments too, which (as one
     example) can be used to identify
       multiple versions of the same file in an archive. This function uses a
     simple linear search through the central
       directory, so it's not very fast.
  
       Alternately, you can iterate through all the files in an archive (using
     mz_zip_reader_get_num_files()) and
       retrieve detailed info on each file by calling mz_zip_reader_file_stat().
  
       - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer
     immediately writes compressed file data
       to disk and builds an exact image of the central directory in memory. The
     central directory image is written
       all at once at the end of the archive file when the archive is finalized.
  
       The archive writer can optionally align each file's local header and file
     data to any power of 2 alignment,
       which can be useful when the archive will be read from optical media. Also,
     the writer supports placing
       arbitrary data blobs at the very beginning of ZIP archives. Archives
     written using either feature are still
       readable by any ZIP tool.
  
       - Archive appending: The simple way to add a single file to an archive is
     to call this function:
  
        mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename,
     const char *pArchive_name,
          const void *pBuf, size_t buf_size, const void *pComment, mz_uint16
     comment_size, mz_uint level_and_flags);
  
       The archive will be created if it doesn't already exist, otherwise it'll be
     appended to.
       Note the appending is done in-place and is not an atomic operation, so if
     something goes wrong
       during the operation it's possible the archive could be left without a
     central directory (although the local
       file headers and file data will be fine, so the archive will be
     recoverable).
  
       For more complex archive modification scenarios:
       1. The safest way is to use a mz_zip_reader to read the existing archive,
     cloning only those bits you want to
       preserve into a new archive using using the
     mz_zip_writer_add_from_zip_reader() function (which compiles the
       compressed file data as-is). When you're done, delete the old archive and
     rename the newly written archive, and
       you're done. This is safe but requires a bunch of temporary disk space or
     heap memory.
  
       2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using
     mz_zip_writer_init_from_reader(),
       append new files as needed, then finalize the archive which will write an
     updated central directory to the
       original archive. (This is basically what
     mz_zip_add_mem_to_archive_file_in_place() does.) There's a
       possibility that the archive's central directory could be lost with this
     method if anything goes wrong, though.
  
       - ZIP archive support limitations:
       No zip64 or spanning support. Extraction functions can only handle
     unencrypted, stored or deflated files.
       Requires streams capable of seeking.
  
     * This is a header file library, like stb_image.c. To get only a header file,
     either cut and paste the
       below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then
     include miniz.c from it.
  
     * Important: For best perf. be sure to customize the below macros for your
     target platform:
       #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
       #define MINIZ_LITTLE_ENDIAN 1
       #define MINIZ_HAS_64BIT_REGISTERS 1
  
     * On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before
     including miniz.c to ensure miniz
       uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be
     able to process large files
       (i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes).
