  Re-initialize logmsgs mutex upon logger initialization to prevent lock errors

  Similar to the patch that moved the fork earlier in the startup sequence to
  prevent mutex errors in the recursive mutex surrounding the read/write thread
  registration lock, this patch re-initializes the logmsgs mutex.  Part of the
  start up sequence before forking the process into the background includes
  reading asterisk.conf; this has to occur prior to the call to daemon in order
  to read startup parameters.  When reading in a conf file, log statements can
  be generated.  Since this can't be avoided, the mutex instead is
  re-initialized to ensure a reset of any thread tracking information.

  This patch also includes some additional debugging to catch errors when
  locking or unlocking the recursive mutex that surrounds locks when the
  DEBUG_THREADS build option is enabled.  DO_CRASH or THREAD_CRASH will
  cause an abort() if a mutex error is detected.
