Comment (by Github):

 Unlock the db queue mutex during InitCon in the startup

 If the program is exiting quickly (before the database is ready), the db
 queue
 is still locked, and then the messages bypass the queue.  When it goes to
 initialize the database connection, the code in mythdbcon logs a message,
 which
 then tries to acquire the lock again, causing a deadlock.

 To get around that, unlock the mutex around the call to InitCon().  I
 think it
 would be better to re-re-think the waiting code so it's not using that
 mutex
 so the mutex can get locked only after the connection is ready, removing
 this
 and the previous unlock/relock.

 Refs #10032.  Hopefully this will fix the deadlocks.
  Branch:    master
