updated ZSTD_estimateCCtxSize()

Browse Source 
added a parameter streaming,
to estimate memory allocation size
when the CCtx is used for streaming (CStream).

Note : this function is not able to estimate
memory cost of a potential internal CDict
which can only happen when starting with ZSTD_initCStream_usingDict()
