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.

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.

removed defaultCustomMem
...
now ZSTD_customCMem is promoted as new default.
Advantages : ZSTD_customCMem = { NULL, NULL, NULL},
so it's natural default after a memset.
ZSTD_customCMem is public constant
(defaultCustomMem was private only).
Also : makes it possible to introduce ZSTD_calloc(),
which can now default to stdlib's calloc()
when it detects system default.
Fixed zlibwrapper which depended on defaultCustomMem.
