a0ba849fe6 changed frameContentSize field to pledgedSrcSizePlusOne 
pledgedSrcSize is proper : it's a promise, not yet fulfilled.
It will be controlled at the end.

PlusOne is meant to have 0 (default) == unknown

8c910d2097 updated ZSTDMT streaming API 
ZSTDMT streaming API is now similar
and has same capabilites as single-thread streaming API.
It makes it easier to blend them together.

01b1549f83 finally converted ZSTD_compressStream_generic() to use {in,ou}Buffer 
replacing the older read/write variables from ZBUFF_* era.
Mostly to help code readability.

Fixed relevant callers.

c4f46b94ce ZSTD_createCCtx_advanced() now uses ZSTD_calloc() 
initially uses calloc() instead of memset().

Performance improvement is unlikely measurable,
since ZSTD_CCtx is now very small,
with all tables transferred into workSpace.

deee6e523f expose ZSTD_compress_generic_simpleArgs() 
which is a binding towards ZSTD_compress_generic()
using only integral types for arguments.

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.

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.

this makes it possible to use `0` to mean:
"do not change strategy"
