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

fix : ZSTDMT_compress_advanced() correctly generates checksum

release input buffers from inside worker thread
...
buffers are released sooner, which makes them available faster for next job.
=> decreases total nb of buffers necessary

optimized memory usage for ZSTDMT_compress()
...
Previously, each job would reserve a CCtx right before being posted.
The CCtx would be "part of the job description",
and only released when the job is completed (aka flushed).
For ZSTDMT_compress(), which creates all jobs first and only join at the end,
that meant one CCtx per job.
The nb of jobs used to be == nb of threads,
but since latest modification,
which reduces the size of jobs in order to spread the load of difficult areas,
it also increases the nb of jobs for large sources / small compression level.
This resulted in many more CCtx being created.
In this new version, CCtx are reserved within the worker thread.
It guaranteea there cannot be more CCtx reserved than workers (<= nb threads).
To do that, it required to make the CCtx Pool multi-threading-safe :
it can now be called from multiple threads in parallel.
