Summary:                    getting warning message every 4 seconds
Description: 
I have a 4-span EuroISDN span, with 

https://issues.asterisk.org/view.php?id=1 connected to telecoms provider

Upgraded libpri and zaptel to latest versions 

zaptel: URL: http://svn.digium.com/svn/zaptel/branches/1.4 Revision: 4696
libpri: URL: http://svn.digium.com/svn/libpri/branches/1.4 Revision: 1684

before this upgrade, I was getting _no_ warning messages, now I am getting
a
 
"WARNING[2659]: chan_dahdi.c:2790 pri_find_dchan: No D-channels available!
 Using Primary channel 109 as D-channel anyway!"

message every 4 seconds

If I remove the definition of the 4th span from zapata.conf, the message
goes away

Asterisk is getting a "No D-channels available!" warning message every 4
seconds.

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.
