Adding handling of BFI (Bad Frame Indicatior) of received TRAU frames
If a bad TRAU frame is received, it is forwarded to MNCC application
as GSM_TCHF_BAD_FRAME. The application can now handle the GAP of
missing audio. (e.g. with extrapolation)
If TRAU frames are forwarded via RTP, bad frames are dropped, but frame
counter and timestamp of RTP sender state is increased.
