Changed ZSTD_createCDict_advanced()
...
It now only uses compressionParameters as argument.
It produces many changes throughout user code,
though hopefully they tend to be simple :
just provide the cParams part from existing ZSTD_parameters.
Some programs might depend on ZSTD_createCDict_advanced() to pass frame parameters.
This change will force them to revisit this strategy and fix it,
since frame parameters are effectively silently ignored in current version.

content size is controlled at bufferless level
...
so it's active for all entry points
Also : added relevant test (wrong content size) in fuzzer

force contentSizeFlag=0 when using ZSTD_initCStream_usingCDict()
...
because by definition srcSize is not known when using this prototype.
added relevant test
Note : this use was already working, because at a later stage
(both ZSTD_compressBegin_usingCDict() and ZSTD_copyCCtx())
pledgedSrcSize=0 is translated into "unknown", no matter the frame parameter.
This is not correct, but of little importance,
as the medium term plan is to no longer set fParams within CDict

Introduce ZSTD_initCStream_internal()
...
This is now the regroup point for ZSTD_initCStream*() functions
ZSTD_initCStream_advanced() now properly checks for parameters validity.
Also : added <assert.h> usage inside zstd_compress.c
Needs ZSTD_DEBUG=1 macro to be triggered.
Will be triggered by default from `tests` directory

optimize ZSTDMT_compress() memory usage
...
does no longer allocate temporary buffers
when there is enough room in dstBuffer to decompress directly there.
(previous method would skip that for 1st chunk only).
Also : fix ZSTD_compressBound() for small srcSize

added ZSTD_getFrameContentSize() to ZSTDMT unit test in fuzzer

Now tests fail, because ZSTDMT_compress() doesn't fill frame content size correctly.
