3b838abf97 ZSTD_CCtx_setParameter : value argument is now int

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.

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"

c7942caff0 Clarify special case of offset history update 
If the current sequence has literal length of zero then an offset value
of three is handled in a special manner. While I implemented a golang
decoder I had to consult the educational decoder for clarification on
the update of the offset history in that case. This commit provides the
clarification that the offset value Repeated_Offset1-1 is handled as a
new offset is added to the offset history accordingly.
