  Add a new libevent_global_shutdown() to free all globals before exiting.
  
  Mark Ellzey added a function libevent_shutdown() which calls a set of
  private functions:
  
         * event_free_globals()
         * event_free_debug_globals()
         * event_free_debug_globals_locks()
         * event_free_evsig_globals()
         * evsig_free_globals()
         * evsig_free_globals_locks()
         * evutil_free_globals()
         * evutil_free_secure_rng_globals()
         * evutil_free_secure_rng_globals_lock()
  
  Nick tweaked this libevent global shutdown code:
  
    - rename the function to emphasize that it's for global resources
    - write more in the doxygen
    - make function brace style consistent
    - add a missing void in a function definition.
