Ok, so I think I've backed out enough of the DB cleanup to prevent
crashing due to shutdown races.
I think the remaining atexit hooks for softIoc shouldn't crash. What is
done is:
> atExit exitDatabase((nil))
For a real IOC (as opposed to a unittest) only doCloseLinks() runs to
cleanup CA_LINK. For records with extended device support it also
disables "I/O Intr" scans and call del_record().

Frees a thread local variable.
> atExit dbCaExit((nil))
Stops the CA link worker.
> atExit cacExitHandler((nil))
Frees a thread local variable.
> atExit twdShutdown((nil))
Stops the watchdog thread.
> atExit errlogExitHandler((nil))
Stops the errlog thread
> atExit ClockTime_Shutdown((nil))
Stops the ClockTimeSync() thread.
None of these should free any global locks so that concurrent operations
using these locks shouldn't operate on free'd memory.
