Fix various problems detected with Valgrind.

Browse Source 
* chan_console accessed pvts after deallocation.
 * cdr_mysql stored a pointer that was freed by realloc()
 * The module loader did not check usecount on shutdown, which led to chan_iax2
 reading a timer that was already unloaded.
 * The event subsystem sometimes creates an event with no IEs.  Due to a corner
 condition, the code would read beyond the memory boundary.
 * res_pktccops did not correctly check whether its monitor thread was started.
