Issues with ISDN calls changing B channels during call negotiations.

The handling of the PROCEEDING message was not using the correct call
structure if the B channel was changed.  (The same for PROGRESS.) The call
was also not hungup if the new B channel is not provisioned or is busy.

* Made all call connection messages (SETUP_ACKNOWLEDGE, PROCEEDING,
PROGRESS, ALERTING, CONNECT, CONNECT_ACKNOWLEDGE) ensure that they are
using the correct structure and B channel.  If there is any problem with
the operations then the call is now hungup with an appropriate cause code.

* Made miscellaneous messages (INFORMATION, FACILITY, NOTIFY) find the
correct structure by looking for the call and not using the channel ID.
NOTIFY is an exception with versions of libpri before v1.4.11 because a
call pointer is not available for Asterisk to use.

* Made all hangup messages (DISCONNECT, RELEASE, RELEASE_COMPLETE) find
the correct structure by looking for the call and not using the channel
ID.
