Windows CI: test lz4 -l on an empty file, NEWS for #1740
...
On Windows, TPool_jobsCompleted() only waited on an auto-reset event,
set when the pending job count drops to 0 :
- with no job submitted, the event is never set and the wait never ends.
`lz4 -l` on an empty file submits no write job,
and decoding the resulting stream (magic number only) submits no decoding job.
- ResetEvent() + increment in TPool_submitJob() race with
decrement + SetEvent() in a worker : the event can stay set while a job
is still pending, so the wait could end before the last write.
#1740 checks the pending job count before waiting, and after each wake up.
The Windows CI never ran lz4 on files :
_test.bat now compresses and decodes an empty file in legacy format.
