background_thread: add max thread count config

Looking at the thread counts in our services, jemalloc's background thread
is useful, but mostly idle.  Add a config option to tune down the number of threads.

Fix a background_thread shutdown issue.

1) make sure background thread 0 is always created; and 2) fix synchronization
between thread 0 and the control thread.

Background threads: fix an indexing bug.

We have a buffer overrun that manifests in the case where arena indices higher
than the number of CPUs are accessed before arena indices lower than the number
of CPUs.  This fixes the bug and adds a test.
