res_pjsip_session: Rewrite o= with external_media_address. 

It now appends the external IP address on the
o= line of the SDP packet.  The decision was made to write
the numeric IP address as opposed to the RFC that states
the FQDN should be used if and when available.  We believe
the usage of literal IP address will help avoid
potential problems.
