Nick Terrell cc1522351f [libzstd] Fix bug in Huffman encoding 
Summary:
Huffman encoding with a bad dictionary can encode worse than the
HUF_BLOCKBOUND(srcSize), since we don't filter out incompressible
input, and even if we did, the dictionaries Huffman table could be
ill suited to compressing actual data.

The fast optimization doesn't seem to improve compression speed,
even when I hard coded fast = 1, the speed didn't improve over hard coding
it to 0.

Test Plan:
I added a test case to the fuzzer which crashed with ASAN before the patch
and succeeded after.

Yann Collet 2bd6440be0 pinned down error code enum values 
Note : all error codes are changed by this new version,
but it's expected to be the last change for existing codes.

Codes are now grouped by category, and receive a manually attributed value.
The objective is to guarantee that
error code values will not change in the future
when introducing new codes.
Intentionnal empty spaces and ranges are defined
in order to keep room for potential new codes.

Yann Collet 3a60efd3a9 policy change : ZSTDMT automatically caps nbThreads to ZSTDMT_NBTHREADS_MAX (#760) 
Previously, ZSTDMT would refuse to create the compressor.
Also : increased ZSTDMT_NBTHREADS_MAX to 256,
updated doc,
and added relevant test

Yann Collet 132e6efd76 switched ZSTDMT_compress_advanced() last argument to overlapLog 
overlapRLog (== 9 - overlapLog) was a bit "strange"
as all other public entry points use overlapLog
