76cb38d085 [zstd] Backport kernel patch from @ColinIanKing 
* Make the U32 table in `FSE_normalizeCount()` static.
* Patch from https://lkml.kernel.org/r/20170922145946.14316-1-colin.king@canonical.com.
* Clang makes non-static tables static anyways. gcc however, does [weird things](https://godbolt.org/g/fvTcED).
* Benchmarks showed no difference in speed.

Yann Collet
6ee05a02b8 added ZSTD_decompress_generic() 
same as ZSTD_decompressStream(),
just for a similar feeling as the compression side, which uses ZSTD_compress_generic()

b8d4a3887f introduced constant ZSTD_frameIdSize 
within zstd_internal.h
This is the size of magic number.

Avoids using `4` directly in source code, which is a bit less meaningful.

* "zip" zips up the minimized corpora, which are ready to deploy.

96f0cde31a minor function rename 
ZSTD_estimateCStreamSize_advanced_usingCParams -> ZSTD_estimateCStreamSize_usingCParams
_usingX is clear.
_advanced feels redundant

360238733a Adds LZ4 support by default if LZ4 is available 
Simple makefile change + quick typename change

Test:

  make clean
  make
  # successfully produces binary without lz4 support

  make clean
  # with flags to pick up my lz4 build
  make MOREFLAGS="-L/home/felixh/prog/lz4/lib -I/home/felixh/prog/lz4/lib"
  # successfully produces binary with lz4 support

  echo "TEST TEST TEST THIS IS A TEST STRING PLEASE TEST THIS PLEASE OK THANK YOU" | \
    ./lz4/lz4 | \
    LD_LIBRARY_PATH=/home/felixh/prog/lz4/lib ./zstd/zstd -d
  # successfully prints TEST TEST TEST THIS IS A TEST STRING PLEASE TEST THIS PLEASE OK THANK YOU

18442a31ff [libzstd] Fix bad window size assert 
The window size is not validated or used in the one-pass API, so there
shouldn't be an assert based on it.
