fa3671eac7 changed ZSTD_BLOCKSIZE_ABSOLUTEMAX into ZSTD_BLOCKSIZE_MAX
Also :
change ZSTD_getBlockSizeMax() into ZSTD_getBlockSize()
created ZSTD_BLOCKSIZELOG_MAX

009d604e00 ZSTD_compress_generic() supports multiple successive frames
also : clarified streaming API implementation

6d4fef36de Added ZSTD_compress_generic()
Used in fileio.c (zstd cli).
Need to set macro ZSTD_NEWAPI to trigger it.

23c256e44b removed useless variable from CCtx
CStream's pledgedSrcSize is no longer necessary
srcSize control is realized within bufferless interface.

7101434ec9 pedantic : added one error check
on a function which (today) never fails.
But who knows, maybe tomorrow ...

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

for improved compiler checks.
Also : ensure most parameters can receive value "0"
to mean "do not change".

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.
