bfabd1d4dc fixed zstreamtest decoding error 
same error (wrong output buffer size) was present
on --mt and --new_api tests.

ca306c1c84 fixed a bug in zstreamtest 
decoder output buffer would receive a wrong size.

In previous version, ZSTD_decompressStream() would blindly trust the caller that pos <= size.
In this version, this condition is actively checked,
and the function returns an error code if this condition is not respected.

This check could also be done with an assert(),
but since this is a user-facing interface, it seems better to keep this check at runtime.

df4e9bba25 fixed constant errors for gcc in c99 mode 
C standard does not consider a `static const int` as a constant.
This is a problem for initializer, and ZSTD_STATIC_ASSERT().
Replaced by macro values

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.

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.
