Fix the local IP address resolution issue in PJSIP, PJMEDIA, and PJSUA, by adding a new API pj_gethostip() to resolve the default local IP address of local host. This new function will work even when local hostname resolution is not set correctly, by detecting the default IP interface in the system.

Also fix compile warnings in iLBC.
