Add ISDN display ie text handling options to chan_dahdi.conf.

Browse Source 
The display ie handling can be controlled independently in the send and
receive directions with the following options:

* Block display text data.

* Use display text in SETUP/CONNECT messages for name.

* Use display text for COLP name updates (FACILITY/NOTIFY as appropriate).

* Pass arbitrary display text during a call.  Sent in INFORMATION
messages.  Received from any message that the display text was not used as
a name.

If the display options are not set then the options default to legacy
behavior.

The arbitrary display text is exchanged between bridged channels using the
AST_FRAME_TEXT frame type.

To send display text from the dialplan use the SendText() application when
the arbitrary display text option is enabled.

@ -49,6 +49,9 @@ libpri channel driver (chan_dahdi) DAHDI changes
--------------------------
* Added moh_signaling option to specify what to do when the channel's bridged
peer puts the ISDN channel on hold.
* Added display_send and display_receive options to control how the display ie
is handled. To send display text from the dialplan use the SendText()
application when the option is enabled.
