2d4d31c18a removed gcc compilation flag -Wbad-function-cast
It makes it more difficult to directly cast the result of a function,
requiring to store the result in an intermediate variable.
It does not necessarily help readability,
and this restriction can be difficult to overcome in some constructions,
like some macros.

also : fixed minor Visual conversion warnings in datagencli.c

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.

a1d6704d7f added ZSTD_estimateCDictSize() and ZSTD_estimateDDictSize()
it complements ZSTD_estimateCCtxSize()
for the special case of ZSTD_initCStream_usingDict()

fc5145955a updated ZSTD_estimateCCtxSize()
added a parameter streaming,
to estimate memory allocation size
when the CCtx is used for streaming (CStream).

Note : this function is not able to estimate
memory cost of a potential internal CDict
which can only happen when starting with ZSTD_initCStream_usingDict()

01a1abfdb5 cli : -d and -t do not stop after a failed decompression
The problematic srcfile will be named on console/log,
but decompression/test will continue onto next file in the list.

31533bacce 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.

Speed accuracy is critical, it cannot be altered by assert.

2c5514c759 fixed ZSTDMT_initCStream_advanced()
Must use the new ZSTD_compressBegin_usingCDict_advanced()
to enforce correct frame parameters

Yann Collet
0bb381dad8 added test for ZSTD_initCStream_advanced()
when params.fParams.contentSizeFlags = 1
and pledgedSrcSize = 0
then srcSize should be considered 0 (empty), and not "unknown"

Yann Collet
4f818182b8 clarified frame parameters for ZSTD_compress*_usingCDict()
created ZSTD_compressBegin_usingCDict_internal(),
which gives direct control to frame Parameters.
ZSTD_resetCStream_internal() now points into it.
