b5c98fbfd0 Added comments on I/O buffer sizes for streaming 
It seems this is still a confusing topic,
as in https://github.com/klauspost/compress/issues/109 .

59a7116cc2 benchfn dependencies reduced to only timefn 
benchfn used to rely on mem.h, and util,
which in turn relied on platform.h.
Using benchfn outside of zstd required to bring all these dependencies.

Now, dependency is reduced to timefn only.
This required to create a separate timefn from util,
and rewrite benchfn and timefn to no longer need mem.h.

Separating timefn from util has a wide effect accross the code base,
as usage of time functions is widespread.
A lot of build scripts had to be updated to also include timefn.

9b784dec7f changed parameter name to ZSTD_c_overlapLog 
from overlapSizeLog.

Reasoning :
`overlapLog` is already used everwhere, in the code, command line and documentation.
`ZSTD_c_overlapSizeLog` feels unnecessarily different.

d8e215cbee created ZSTD_compress2() and ZSTD_compressStream2() 
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().

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.

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.
