pjsip: Add 'PJSIP_AOR' and 'PJSIP_CONTACT' dialplan functions.
The PJSIP_AOR dialplan function allows inspection of configured AORs including
what contacts are currently bound to them.
The PJSIP_CONTACT dialplan function allows inspection of contacts in existence.
These can include both externally added (by way of registration) or permanent
ones.
