19e5f2a35b removed some constants and _simpleArgs() from staging 
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.

ff8d371708 modified ZSTD_CCtx_reset() 
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.

d7e10a774a added constant ZSTD_WINDOWLOG_LIMIT_DEFAULT 
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)

b83d1e7714 removed some static const variables 
and replaced by traditional macro constants.

Unfortunately, C doesn't consider `static const` to mean "constant"

105677c6db created ZSTDMT_toFlushNow() 
tells in a non-blocking way if there is something ready to flush right now.
only works with multi-threading for the time being.

Useful to know if flush speed will be limited by lack of production.
