* Add the ability to exchange subaddresses for ETSI PTMP, ETSI PTP, and
Q.SIG for call transfer.
* Fix ETSI PTMP to send the correct messages depending on the call state
for call transfer. NOTE: Some ISDN phones only handle the NOTIFY message
that the EN 300-369 spec says should be sent only if the call has not
connected yet.

This feature passes ETSI AOC-S, AOC-D, and AOC-E message information to
the upper layer (i.e. Asterisk) for processing.
Relevant specification: EN 300 182
Consideration was made for the possible future addition of Q.SIG AOC
support (ECMA-212) with the events passed to the upper layer.

Added ability to send and receive ETSI ECT messages to eliminate tromboned
calls.
Added ETSI support to an existing API call to send ECT messages when the
upper level indicates to transfer specified calls.
The libpri API was extended to indicate to the upper layer that the far
end requests the transfer of the indicated calls.

Call Completion Supplementary Service (CCSS) added for the following
switch types: ETSI PTMP, ETSI PTP, Q.SIG.
Specifications:
ETS 300 359 CCBS for PTMP and PTP
ETS 301 065 CCNR for PTMP and PTP
ECMA-186 Call Completion for Q.SIG
Several support services were added to support CC:
Dummy Call Reference.
Q.931 REGISTER message.
Dynamic expansion of the number of available timers (up to 8192).
Enhanced facility message handling.
Current implementation limitations preclude the following:
CC service retention is not supported.
Q.SIG path reservation is not supported.

1) No sent messages will remain in the APDU queue unless they have an
active timer to remove them. The dummy call reference call and global
call reference call structures will not act like a memory leak to sent
messages.
2) The new T-RESPONSE timer will be the generic response guard if the
standards do not otherwise specify a timer for a message response.
3) The callback will be called. If it is called because of a response
message, then the callback has an opportunity to indicate if more
responses are expected.

The facility ie queue needs to remove facilities that have been sent.
Otherwise, the queue just grows until the call is terminated. AOC
messages can clog the queue during a long call and the dummy call
reference may never be deleted.
Also removed unneeded elements of struct apdu_event. The callback
function was not a good idea since many facility messages do not have
responses and the callback would prevents removal of events from the list.

* Added support for BRI PTMP NT mode. (Overlap dialing NT -> TE not supported.)
* Added handling of received HOLD/RETRIEVE messages and the optional ability
to transfer a held call on disconnect similar to an analog phone.
* Added CallRerouting/CallDeflection support for Q.SIG, ETSI PTP, ETSI PTMP.
Will reroute/deflect an outgoing call when receive the message.
Can use the DAHDISendCallreroutingFacility to send the message for the
supported switches.
* Added ability to send/receive keypad digits in the SETUP message.
Send keypad digits in SETUP message: Dial(DAHDI/g1[/K<keypad_digits>][/extension])
Access any received keypad digits in SETUP message by: ${CHANNEL(keypad_digits)}

Add Connected Line Presentation (COLP) support to chan_dahdi/libpri as an
addition to issue 8824. This is the libpri portion. COLP support is now
available for ETSI PTP, ETSI PTMP, and Q.SIG with this patch.
