[qa] Test non-atomic chainstate writes
Adds new functional test, dbcrash.py, which uses -dbcrashratio to exercise the logic for recovering from a crash during chainstate flush. dbcrash.py is added to the extended tests, as it may take ~10 minutes to run Use _Exit() instead of exit() for crash simulation This eliminates stderr output such as: terminate called without an active exception or Assertion failed: (!pthread_mutex_destroy(&m)), function ~recursive_mutex, file /usr/local/include/boost/thread/pthread/recursive_mutex.hpp, line 104. Eliminating the stderr output on crash simulation allows testing with test_runner.py, which reports a test as failed if stderr is produced.
