Store the cause code that is returned when trying to create a channel in ChanIsAvail in the
AVAILCAUSECODE dialplan variable instead of overwriting the device state in AVAILSTATUS.

   collisions, the channel name format is changed.
   The new channel naming for PRI channels is:
   DAHDI/i<span>/<number>[:<subaddress>]-<sequence-number>

+* The ChanIsAvail application has been changed so the AVAILSTATUS variable
+  no longer contains both the device state and cause code. The cause code
+  is now available in the AVAILCAUSECODE variable. If existing dialplan logic
+  is written to expect AVAILSTATUS to contain the cause code it needs to be
