Changes
-------

Rebase to resolve a conflict in res_pjsip.c


Bugs: ASTERISK-24731
    https://issues.asterisk.org/jira/browse/ASTERISK-24731


Repository: Asterisk


Description
-------

This patch allows all PJSIP modules to shutdown cleanly, once approved we'll be 
able enable it in the Bamboo Reference Checks Job.

* Move most of res_pjsip:module_unload to unload_pjsip to resolve crashes 
caused by running PJSIP functions from non-PJSIP threads.
* Remove call to pjsip_endpt_destroy(ast_pjsip_endpoint), it was causing 
crashes in some cases.  In theory pj_shutdown() should take care of this for us.
* Mark res_pjsip_keepalive and res_pjsip_session as allowed to unload at 
shutdown.
* Resolve leaked config global in res_pjsip_notify.
* Unregister pubsub pjsip service module.
* Implement cleanup for res_pjsip_session.
* Fix a pre-existing FRACK in res_pjsip_outbound_registration.

More about res_pjsip_outbound_registration:
tests/channels/pjsip/ami/show_registrations_outbound has an AO2 FRACK during 
shutdown.  I get this error with or without my patch.  I've removed what I 
believe is an extra unref, but this doesn't solve all the FRACK's.

Testing
-------

All of tests/channels/pjsip.  Some tests still have reference leaks, but most 
tests do not.

Can someone retest tests/channels/pjsip/ami/show_registrations_outbound to 
confirm that I haven't made it worse?  Seems to make no difference on my 
system, but Bamboo doesn't seem to have a problem with this test.


Thanks,

Corey Farrell
