MDEV-4113: Assertion (group->connection_count > 0) fails with Percona server in replication test.
...
Assertion happens in replication thread during THD destruction, when thread calls my_sync(), which in turn calls thd_wait_begin() callback. Connection count can be 0, because the counter was decremented before THD destructor.
This assertion currently reproducible only in Percona server and not in MariaDB, due to differences in replication code.
Fixed by moving code to decrement connection counter after the THD destructor.

MDEV-531 : Warning: Forcing close of thread ... in rpl_binlog_index
...
Use post_kill_notification in for one_thread_per_connection scheduler,
the same as already used in threadpool, to reliably wake a thread stuck in
read() or in different poll() variations.

some more whitespace, remove pending_thread_start_count. increment counters (thread_group->count, thread_group->active_thread_count) whenever mysql_create_thread returns success.

Instead, use function that loops over groups and
calculates idle threads for "show status".

Allow for faster creation of threads in corner cases where pool would be overloaded with long non-yielding queries.
...
To allow it, change minimum of thread_pool_stall_limit to be 10 milliseconds.
Also introduce a new parameter to oversubscribe a group . Number of threads running in parallel would be higher than it normally should, leading to thrashing, but it may improving preemptiveness, which is useful for the described corner case.
