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.

132e6efd76 switched ZSTDMT_compress_advanced() last argument to overlapLog
overlapRLog (== 9 - overlapLog) was a bit "strange"
as all other public entry points use overlapLog

990449b89d 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"

037466245f refactor ZSTD_check_compressionLevel_monotonicIncrease_memoryBudget()
use less macro statements
the initial version was meant to work with STATIC_ASSERT
but since it doesn't work and needs assert()
it's possible to rewrite it using normally compiled code
which is better for compiler.

Downside : the error message is less precise.
There is a DEBUGLOG(3,) to compensate.

813535105b added function to control monotonic memory budget increase of ZSTD_defaultCParameters[0]
It's a runtime test, based on assert(),
played once, on first ZSTD_getCParams() usage,
when ZSTD_DEBUG is enabled.

31af8290d1 ZSTD_estimateCCtx_advanced()
ZSTD_estimateCCtx() is now a "simple" function,
taking int compressionLevel as single argument.

ZSTD_estimateCCtx_advanced() takes a CParams argument,
which is both more complete and more complex to generate.

c08e649e95 first implementation of bench.c with new API ZSTD_compress_generic()
Doesn't speed optimize this buffer-to-buffer scenario yet.
Still internally defers to streaming implementation.

Also : fixed a long standing bug in ZSTDMT streaming API.

c7fe262dc9 added ZSTD_initStaticCCtx()

static CCtx will only use provided memory area,
it will never resize nor malloc.

b0739bcf8f simplified reset by removing full-reset policy
this was meant to be applied prior to dictionary loading.
But effectively, it seems redundant with later loading stage,
so it can be skipped safely.

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.
