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.

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

132e6efd76 switched ZSTDMT_compress_advanced() last argument to overlapLog
overlapRLog (== 9 - overlapLog) was a bit "strange"

8ef666c325 slightly increased buffer pool, to cover normal "full load" scenarios
2 buffers per active worker
+ 1 buffer for input loading
+ 1 buffer for "next input" when submitting current one
+ 1 buffer stuck in queue

052a95f77c fix : ZSTDMT_compress_advanced() correctly generates checksum
