Changeset 2444 for pjproject/branches/projects/aps-direct/pjmedia/include/pjmedia-codec/amr_helper.h

Message:

• Added support for codec ILBC, G729, and AMR.
• Updated audio switch board to make user possible to update its port 0 (master port) attributes, this is needed since sound device need to be reopened (e.g: for changing ptime or codec) while conf is not recreated.
• Added new API to AMR helper to resolve mode/frame-type based on frame len.
• Updated pmedia_frame_ext helper functions for a bit optimization.
