6d9c1cb0d9 Optimized calls to pri_schedule_del(). 
There is no need to test if a scheduled event is running before calling
pri_schedule_del().

3a1739883b There are two changes in this commit that are bug fixes for various Q.921 issues found in internal testing. 
Both were exposed/introduced by the TBR4 compliance patch for bug #12861, in changing how retransmissions and in how
the transmission queue was maintained.  TX-RX message flow and acknowledgement was severely restricted,
since the patch changed the behavior so that pending untransmitted frames would not actually be send until
the next RR was received in normal circumstances, or REJ when a reject frame was received.  On busy links,
this can severly limit the amount of useful traffic that is sent, and can slow down message transmission.

Until someone can point out where in Q.921 it is mandated for us to wait for RR frames to start sending
untransmitted messages, the first change is to allow us to send untransmitted frames when we receive new
I frames as well, with updated N(R).

The other bug fixed is a situation caused by the restricted traffic flow, if an outside process tries to send
an I-frame asynchronous to an RR frame, when the transmit window was previously closed and then opened up but 
an RR has not been received yet.  A bug was found with the integration of the old transmit code with the new reject 
handling code which caused the new frame to be sent immediately, regardless if there were any pending untransmitted 
I-frames in the queue to be sent and causing an out of order I-frame to be sent to the other side.  This bug is 
also fixed in this patch.

18fa4716a5 Add service maintenance message support 
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.

3d91cd5e30 A couple of last BRI fixes in libpri... don't discard pending iframes when we call the q921_dchannel_up routine, since we need to be able to send the ones that were queued up while the D-channel went down and is being reactivated. Also fix some buggy logic in the frame transmission decision code.
