Changeset 633 for pjproject/trunk/pjmedia/src/pjmedia/null_port.c

Message:

Added pjmedia_port_info_init() to fill in pjmedia_port_info structure, avoiding manual initialization and thus improves consistency (and probably reduces size by a tiny bit). This involves modification in quite few places.
