Fixes #1047 (Don't send UPDATE if remote doesn't support it (thanks Bogdan Krakowski for the report)) and fixes #1097 (Support sending UPDATE without SDP). Details:
- Session timer fixes:
- will look at remote capability in Allow header
- if UPDATE is supported, will send UPDATE without SDP first.
If this fails, will send UPDATE with SDP
- otherwise will send re-INVITE
- PJSUA-LIB will look at dialog's remote capability to determine
whether re-INVITE or UPDATE should be sent to change default
addresses after ICE negotiation.
- pjsip_inv_update() now allows NULL offer, in which case the
UPDATE will be sent without SDP.
