Added support for specifying IP address in PJSUA-LIB/pjsua.
This option can be used for example to select the IP
interface of SIP/RTP/RTCP transports, or to specify the
public IP address of NAT/router in case port forwarding is
used.
For SIP transports, this feature works for both UDP and
TCP transports.
Changes:
- added public_ip field in pjsua_transport_config, and
change SIP and media transport creation to consider this
option.
- added --ip-addr option in pjsua
- added pjsip_tcp_transport_start2() which allows
specifying alternate TCP published address when creating
TCP transports.
