53e1f0504e zstdmt debug traces compatibles with mingw
since mingw does not have `sys/times.h`,
remove this path when detecting mingw compilation.

6d222c437c Set requestedParams in ZSTD_initCStream*()
The correct parameters are used once, but once `ZSTD_resetCStream()` is
called the default parameters (level 3) are used. Fix this by setting
`requestedParams` in the `ZSTD_initCStream*()` functions.

The added tests both fail before this patch and pass after.

4489daec09 slightly adjusted default-distribution threshold
depending on strategy.
fast favors faster compression and decompression speeds.

[zstdmt] Fix jobsize bugs (#1205)
[zstdmt] Fix jobsize bugs

* `ZSTDMT_serialState_reset()` should use `targetSectionSize`, not `jobSize` when sizing the seqstore.
  Add an assert that checks that we sized the seqstore using the right job size.
* `ZSTDMT_compressionJob()` should check if `rawSeqStore.seq == NULL`.
* `ZSTDMT_initCStream_internal()` should not adjust `mtctx->params.jobSize` (clamping to MIN/MAX is okay).

Thread Pool resize

fbd5dfc1b1 changed POOL_resize() return type to int
return is now just en error code.
This guarantee that `ctx` remains valid after POOL_resize().
Gets rid of internal POOL_free() operation.

166901dc72 reduced POOL_resize() restriction
It's not necessary to ensure that no job is ongoing.
The pool is only expanded, existing threads are preserved.
In case of error, the only option is to return NULL and terminate the thread pool anyway.

066fbbfe1c make zstdmt resize its context
when nbThreads change.

Technically, it only expands.
But when instructed to use less threads,
the thread pool will limit nb of concurrent threads.

3841dbac84 Adjust advanced parameters to source size
In the new advanced API, adjust the parameters even if they are explicitly
set. This mainly applies to the `windowLog`, and accordingly the `hashLog`
and `chainLog`, when the source size is known.

fa41bcc2c2 grouped debug functions into debug.h
There were 2 competing set of debug functions
within zstd_internal.h and bitstream.h.
They were mostly duplicate, and required care to avoid messing with each other.

There is now a single implementation, shared by both.

Significant change :
The macro variable ZSTD_DEBUG does no longer exist,
it has been replaced by DEBUGLEVEL,
which required modifying several source files.
