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.

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

a00e9599f1 removed -g from DEBUGFLAGS 
It inflates binary sizes, which is negative for the Windows build.
It also makes it impossible to check if 2 different source codes
get nonetheless compiled to the same binary,
since checksum will be different, due to integrated source code.

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.

201e8c8157 programs/Makefile: remove zstd-internal target 
zstd-internal was intended to be a helper target, but it doesn't help
at all, what it does in practice is a useless rebuild of zstd every time
"make zstd" is invoked.

Fixes: 030ac243a0 ("Changed Makefile to generate zstd with .gz support by default")
