f1571dad8f Merge pull request #838 from stellamplau/ldm-mergeDev 
Add long distance matcher

c95c0c9725 modified util::time API 
for easier invocation.
- no longer expose frequency timer :
it's either useless, or stored internally in a static variable (init is only necessary once).
- UTIL_getTime() provides result by function return.

c08e649e95 first implementation of bench.c with new API ZSTD_compress_generic() 
Doesn't speed optimize this buffer-to-buffer scenario yet.
Still internally defers to streaming implementation.

Also : fixed a long standing bug in ZSTDMT streaming API.

31533bacce Changed ZSTD_createCDict_advanced() 
It now only uses compressionParameters as argument.
It produces many changes throughout user code,
though hopefully they tend to be simple :
just provide the cParams part from existing ZSTD_parameters.

Some programs might depend on ZSTD_createCDict_advanced() to pass frame parameters.
This change will force them to revisit this strategy and fix it,
since frame parameters are effectively silently ignored in current version.

4e709712e1 Decompressed size functions now handle multiframes and distinguish cases 
- Add ZSTD_findDecompressedSize
    - Traverses multiple frames to find total output size
- Add ZSTD_getFrameContentSize
    - Gets the decompressed size of a single frame by reading header
- Deprecate ZSTD_getDecompressedSize

736788f8e8 added streaming fuzzer tests for MT API 
Also : fixed corner case, where nb of jobs completed becomes > jobQueueSize
which is possible when many flushes are issued
while there is not enough dst buffer to flush completed ones.

5eb749e734 ZSTDMT_compress() creates a single frame 
The new strategy involves cutting frame at block level.
The result is a single frame, preserving ZSTD_getDecompressedSize()

As a consequence, bench can now make a full round-trip,
since the result is compatible with ZSTD_decompress().

This strategy will not make it possible to decode the frame with multiple threads
since the exact cut between independent blocks is not known.
MT decoding needs further discussions.
