switch to single-pass mode directly into output buffer
when outputSize >= ZSTD_compressBound(inputSize).
Speed gains observed with fullbench (~+15% on level 1)
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.
The following warning appears during the build. Fixed the review comments too.
zstd/lib/common/bitstream.h: In function ‘BIT_initDStream’:
zstd/lib/common/bitstream.h:277:33: warning: this statement may fall through [-Wimplicit-fallthrough=]
case 7: bitD->bitContainer += (size_t)(((const BYTE*)(srcBuffer))[6]) <<
(sizeof(bitD->bitContainer)*8 - 16);

keep dev branch status only
creates a binary archive without the `programs` directory
...
clearer separation between variables and buffers
clearer buffers category
kept static buffers at the beginning, favoring cache locality
(it will be easier to add FSE tables there later)
This break a few assumptions that hashTable was always at the beginning.
This is fixed.
And remaining assumptions (namely that tables stand next to each other in memory)
are now tested with assert.
