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.

a57b4df85f removed literalCompression directive

153bc1c004 removed limit ZSTD_TARGETLENGTH_MAX
this makes it possible to specify extremely large negative compression levels,
achieving the side effect as "no compression".

It will also be possible to define larger targetlength for ultra compression mode.

There is no adverse side effect due to removing this limit.
