Fixes issue with undefined audio codecs in chan_iax2

During iax2 call negotiation, supported codecs are passed in an Information Element containing a 2 byte field where each bit correlates to a specific codec.  In 1.6 only audio codec bits 0-12 are defined, leaving bits 13-14 undefined.  By default all bits are enabled unless specified otherwise.  Since its a 2 byte field and 13-14 are not defined, these bits are never turned off.  In trunk, bits 13-14 are defined, which means 1.6 is advertising support for codecs it does not have when talking to trunk.  I fixed this by adding #define for undefined audio codec bits.  These bits are then removed from iax2's full bandwidth capabilities.
