    AMI actions DAHDIHangup and DAHDITransfer have no effect.

    The AMI actions DAHDIHangup and DAHDITransfer have no effect on a DAHDI
    channel.  These two AMI actions are highly specialized to analog channels
    and appear to make the channel behave like a jack port for headsets.

    * Made the faked DAHDI event get processed before a normal media stream
    read in dahdi_read() instead of trying to trigger an exception read by
    setting the AST_FLAG_EXCEPTION flag.  Apparently a change was made long
    ago that changed how AST_FLAG_EXCEPTION is processed in the core.
    Unfortunately, the faked DAHDI events no longer worked when that happened.

    * Updated the DAHDI AMI action documentation for the following actions:
    DAHDITransfer, DAHDIHangup, DAHDIDialOffhook, DAHDIDNDon, DAHDIDNDoff,
    DAHDIShowChannels, and DAHDIRestart.

    * Made use sscanf() instead of atoi() for better error checking of the
    DAHDIChannel header string.
