    * Removed Codecs/Channels:
         1. codec_g723 was removed because the actual codec implementation it was designed to use is not available
         2. chan_modem_* stuff is gone because the kernel support for those interfaces is old, buggy and unsupported
    * New Utils:
         1. aelparse -- compile .ael files outside of asterisk
         2. muted -- turn down the volume on the sound card when certain phones are ringing or off-hook... automagically.
