ZSTD_compress_generic() is renamed ZSTD_compressStream2().
Note that, for the time being,
the "stable" API and advanced one use different parameter planes :
setting parameters using the advanced API does not influence ZSTD_compressStream()
and using ZSTD_initCStream() does not influence parameters for ZSTD_compressStream2().
constants that *may* change in the future
will be accessed through functions instead
(to be created).
_simpleArgs() variant do not have (yet) a clear enough added value
to deserve "stable" status.
- Factor out LDM's hash function for reuse
- Add rsyncable mode to zstdmt and expose it via the advanced API
- Fix `-B`/`--block-size` to actually set the job size
- Add rsyncable tests to `zstreamtest` and `playTests.sh`
Tested by:
```
> cat A.100MB B.100MB C.100MB D.100MB E.100MB | zstd --rsyncable -fo src/file.zst
/*stdin*\ : 48.22% (524288000 => 252837782 bytes, src/file.zst)
> rsync -rc --stats src devbigvm:/data/users/terrelln/rsync-test
Total bytes sent: 252868779
total size is 252837782 speedup is 1.00

Close#1155.
which now accepts an enum,
to distinguish between resetting the session, or the parameters (or both).
removed ZSTD_CCtx_resetParameters(), which is redundant.
start replacing invocation of ZSTD_CCtx_reset*() functions
Updated advanced API documentation
trimmed down amount of API staged in RC,
in particular, all functions related to ZSTD_CCtxParams()
seem too advanced.
answering #1407.
Also : removed obsolete function ZSTD_setDStreamParameter()
which could only be used with one parameter (DStream_p_maxWindowSize).
Now replaced by ZSTD_DCtx_setWindowSize() (which exists since a few revisions)
