new field : ZSTD_frameHeader.frameType
...
Makes frame type (zstd,skippable) detection more straighforward.
ZSTD_getFrameHeader set frameContentSize=ZSTD_CONTENTSIZE_UNKNOWN to mean "field not present"

[libzstd] Fix memcpy() on potential NULL source
...
* `ZSTD_decompressStream_generic()` `ip` may be `NULL` for one of the calls
to `memcpy()`
* Assert the source is not `NULL` for calls to `memcpy()` where I believe
the source should not be `NULL`.

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.

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.

still need this differentiation.

ZSTD_frameParams => ZSTD_frameHeader
ZSTD_getFrameParams() -> ZSTD_getFrameHeader()

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.

This decoder variant is detrimental to x86 architecture
likely due to register pressure.
Note that the variant is disabled for all 32-bits targets.
It's unclear if it would help for different architectures,
such as ARM, MIPS or PowerPC.
