731f4b70fc Fix & fuzz ZSTD_generateSequences 
This function was seriously flawed:
* It didn't do output bounds checks
* It produced invalid sequences when an uncompressed or RLE block was emitted
* It produced invalid sequences when the block splitter was enabled
* It produced invalid sequences when ZSTD_c_targetCBlockSize was enabled

I've attempted to fix these issues, but this function is just a bad idea,
so I've marked it as deprecated and unsafe. We should replace it with
`ZSTD_extractSequences()` which operates on a compressed frame.

2e29728797 fix #3583 
As reported by @georgmu,
the previous fix is undone by the later initialization.
Switch order, so that initialization is adjusted by special case.

cb0cad9b79 reduce Max nb Workers to 64 in 32-bit mode 
and restored limit to 256 when in 64-bit mode
(it was reduced to 200 to give more room for 32-bit).

This should fix test instability issues
using lot of threads in 32-bit environments.

de0499f7fa [libzstd] Require ZSTD_MULTITHREAD to create a ZSTDMT_CCtx 
ZSTDMT was broken when compiled without ZSTD_MULTITHREAD defined,
because `ZSTD_CCtx_setParameter(cctx, ZSTD_c_nbWorkers, nbWorkerss)`
failed. It was detected by the MSVC test which runs the fuzzer with
multithreading disabled.

This is a very niche use case of a deprecated API, because the API is
inefficient and synchronous, since `threading.h` will be synchronous.
Users almost certainly don't want this, and anyone who tested their code
should realize that it is broken. Therefore, I think it is safe to
require `ZSTD_MULTITHREAD` to be defined to use ZSTDMT.
