6ee05a02b8 added ZSTD_decompress_generic() 
same as ZSTD_decompressStream(),
just for a similar feeling as the compression side, which uses ZSTD_compress_generic()

b8d4a3887f introduced constant ZSTD_frameIdSize 
within zstd_internal.h
This is the size of magic number.

Avoids using `4` directly in source code, which is a bit less meaningful.

18442a31ff [libzstd] Fix bad window size assert 
The window size is not validated or used in the one-pass API, so there

b3f33ccfb3 use ZSTD_decodingBufferSize_min() inside ZSTD_decompressStream() 
Use same definition as public one

Yann Collet
058ed2ad33 ZSTD_decodingBufferSize_min() 
supporting function for bufferless streaming API (ZSTD_decompressContinue())
makes it possible to correctly size a round buffer for decoding using this API.

also : added field blockSizeMax within ZSTD_frameHeader,
as it's a necessary information to know when to restart at beginning of decoding buffer.

abe12b3399 [libzstd] Fix bug in Huffman decompresser 
The zstd format specification doesn't enforce that Huffman compressed
literals (including the table) have to be smaller than the uncompressed
literals. The compressor will never Huffman compress literals if the
compressed size is larger than the uncompressed size. The decompresser
doesn't accept Huffman compressed literals with 4 streams whose compressed
size is at least as large as the uncompressed size.

* Make the decompresser accept Huffman compressed literals whose size
  increases.
* Add a test case that exposes the bug. The compressed file has to be
  statically generated, since the compressor won't normally produce files
  that expose the bug.

2bd6440be0 pinned down error code enum values 
Note : all error codes are changed by this new version,
but it's expected to be the last change for existing codes.

Codes are now grouped by category, and receive a manually attributed value.
The objective is to guarantee that
error code values will not change in the future
when introducing new codes.
Intentionnal empty spaces and ranges are defined
in order to keep room for potential new codes.

ae728a43b8 removed defaultCustomMem 
now ZSTD_customCMem is promoted as new default.

Advantages : ZSTD_customCMem = { NULL, NULL, NULL},
so it's natural default after a memset.

ZSTD_customCMem is public constant
(defaultCustomMem was private only).

Also : makes it possible to introduce ZSTD_calloc(),
which can now default to stdlib's calloc()
when it detects system default.

Fixed zlibwrapper which depended on defaultCustomMem.

2e4db3e531 fixed performance regression with ZSTD_decompress() on small files 
memset() was a quick fix to initialization problems,
but initialize too much space (tables, buffers)
which show up in decompression speed of ZSTD_decompress()
since it needs to recreate DCtx at each invocation.

Fixed by only initialization relevant pointers and size fields.

542c9dfcf8 changed name frameParams into frameHeader 
ZSTD_frameParams => ZSTD_frameHeader
ZSTD_getFrameParams() -> ZSTD_getFrameHeader()

The new naming is more distinctive from ZSTD_frameParameters,
which is used during compression.

ZSTD_frameHeader is clearer in its intention to described frame header content.
It also implies we are decoding a ZSTD frame, hence we are at decoding stage.

4bcc69b761 solves warnings when compiling with global XXH_STATIC_LINKING_ONLY 
XXH_STATIC_LINKING_ONLY protection macro is intended to be triggered just before the include.
The main idea is to keep this setting local :
user module shall explicitly understand and accept the static linking restriction
which becomes transparent when triggering the macro at project level.
Global definition also triggers redefinition warnings for user modules which do locally define the macro.

This new version compiles lib and cli without warning when the macro is set globally.
That's not a scenario to be recommended, since it trades a local effect for a global one,
but it was easy enough to provide from zstd side.

8157a4c3cc Fix dictionary loading bug causing an MSAN failure 
Offset rep codes must be in the range `[1, dictSize)`.
Fix dictionary loading to reject `0` as a offset rep code.

064a143520 Fix execSequence wildcopy undefined behavior 
execSequence relied on pointer overflow to handle cases where
`sequence.matchLength < 8`.  Instead of passing an `size_t` to
wildcopy, pass a `ptrdiff_t`.

e474aa55b4 Fix decompression buffer overrun 
Allows an adversary to write up to 3 bytes beyond the end of the buffer.
Occurs if the match overlaps the `extDict` and `currentPrefix`, and the
match length in the `currentPrefix` is less than `MINMATCH`, and
`op-(16-MINMATCH) >= oMatchEnd > op-16`.
