fd9f1638ea MDEV-5205 - MariaDB does not start if more than 128 cpu's are available 
- thread_pool_size command line option upper limit increased to 100 000
  (same as for max_connections)
- thread_pool_size system variable upper limit is maximum of 128 or
  the value given at command line
- thread groups are now allocated dynamically

Different limit for command line option and system variable was done to
avoid additional mutex for all_groups and threadpool_max_size.

d212991e89 Get rid of idle thread counter atomic variable. 
Instead, use function that loops over groups and 
calculates  idle threads for  "show status".

c216c9f0f0 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.
