[contrib/pzstd] Prevent hangs when there are errors
...
When two threads are using a WorkQueue and the reader thread exits due
to an error, it must call WorkQueue::finish() to wake up the writer
thread. Otherwise, if the queue is full and the writer thread is waiting
for a free slot, it could hang forever.
This can happen in pratice when decompressing a large, corrupted file
that does not contain pzstd skippable frames.

[opt] Fix too short of match getting generated
...
The optimal parser with LDM enabled using minMatch > 3 could generate a match
length of 3 when minMatch >= 4. This is not allowed.
1. Fix the bug
2. Add validation logic to `ZSTD_buildSeqStore()` in debug mode for all block
compressors that checks we never generate too short a match. This way we don't
rely on the `generate_sequences` fuzzer to find this issue.
