Revamped the I-frame retransmission queue to better comply with Q.921:
Figure B.7/Q.921 (sheet 1 of 10) and Figure B.9/Q.921 (Sheet 5 of 5). The
changes prevent retransmitting I-frames when the peer is busy (RNR) (Q.921
Section 5.6.5) and eliminate an unnecessary delay sending new I-frames
after an I-frame retransmission.

For PTP links, libpri generated the PRI_EVENT_DCHAN_DOWN event every time
it failed to bring layer 2 up because the physical layer is down.
For PTP links, made generate the PRI_EVENT_DCHAN_UP/PRI_EVENT_DCHAN_DOWN
only when it enters/exits the Q.921 superstate consisting of states
7(Q921_MULTI_FRAME_ESTABLISHED) and 8(Q921_TIMER_RECOVERY).
Also changed the PTP link restart delay to be link specific instead of D
channel specific because the GR-303 PTP switch types have more than one
Q.921 link.

This completes the layer 2 link and Q.931 call control restructuring.
Some code is now simplified since there is only one D channel control
structure and the amount of allocated memory is reduced.

This is in anticipation of extracting a layer 2 link structure out of
struct pri.
Also completes fixing timer value access for the rest of libpri. The
timer access must always be on the D channel control structure (Master).
May have fixed some events from timeouts not being passed to the upper
layer. The timeout events must always be on the D channel control
structure (Master).

* 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)}

This adds support for two new message types: Service and Service Acknowledge.
When a channel receives a service message it will either take the channel in
or out of service and then send a service acknowledgment. Although not
enforced here (enforced in chan_dahdi), the service messages are only supported
with switch types 4ess/5ess. The required Asterisk changes will be coming next.
