ae728a43b8 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.

5bcef1ada2 removed mtctx->cstream 
use the first cctx in pool when ZSTDMT is used in single-thread mode
now that cctx and cstream are the same object.

25989e361c updated ZSTD_estimate?DictSize() to pass parameter byReference 
resulting ?Dict object is smaller when created byReference.
Seems better than a documentation note.

2e4db3e531 fixed performance regression with ZSTD_decompress() on small files 
memset() was a quick fix to initialization problems,
but initialize too much space (tables, buffers)
which show up in decompression speed of ZSTD_decompress()
since it needs to recreate DCtx at each invocation.

Fixed by only initialization relevant pointers and size fields.

11ea2f7fda Merged ZSTD_DCtx and ZSTD_DStream objects 
They are now the same object.
It's recommended to keep both types in source code
as previous versions of library (<v1.3.0)
still need this differentiation.

b81f19ffce move MEM_readMINMATCH() into zstd_opt.h

c7fe262dc9 added ZSTD_initStaticCCtx() 
makes it possible to statically or externally allocate CCtx.
static CCtx will only use provided memory area,
it will never resize nor malloc.

1880337c30 Simplifier compression call graph 
Everything converge towards ZSTD_compressBegin_internal
which delegated to ZSTD_copyCCtx_internal if cdict!=NULL.

This simplifies routing which was previously depending on cdict.

b0739bcf8f simplified reset by removing full-reset policy 
this was meant to be applied prior to dictionary loading.
But effectively, it seems redundant with later loading stage,
so it can be skipped safely.
