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

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.
