6078b21698 Remove nul octets from IE data that is normally treated as strings.
Sometimes ie values received from carriers contain nul octets in values
normally treated by libpri as nul terminated strings.  A discussion on the
asterisk-users list determined that the best thing to do in the situation
is to delete the nul octets and unconditionally report/log when that
happens.

* Remove nul octets from the following ie's and generate an unconditional
log message to the upper layer when they are removed:
Connected Number
Connected Address
Redirecting Number
Original Called Number
Redirection Number
Called Party Number
Calling Party Number
Display
Keypad Facility

4e7c3d1462 Implement handling a multi-channel RESTART request.
The channel id ie can supply a slotmap or list of channels.  For a RESTART
message, this can be handy to indicate multiple channels that need to be
restarted at the same time.

An incoming RESTART request will now generate a PRI_EVENT_RESTART to the
upper layer for each channel indicated in the request.  If the event is
successfully generated for all indicated channels then a
RESTART_ACKNOWLEDGE is sent back to the peer indicating all channels
restarted.

* Add the ability to process a channel id ie channel list with a RESTART
request.

* Add the ability to process slotmaps with a RESTART request.

c5ec479bd2 Outgoing BRI calls fail when using Asterisk 1.8 with HA8, HB8, and B410P cards.
France Telecom brings layer 2 and layer 1 down on BRI lines when the line
is idle.  When layer 1 goes down Asterisk cannot make outgoing calls and
the HA8 and HB8 cards also get IRQ misses.

The inability to make outgoing calls is because the line is in red alarm
and Asterisk will not make calls over a line it considers unavailable.
The IRQ misses for the HA8 and HB8 card are because the hardware is
switching clock sources from the line which just brought layer 1 down to
internal timing.

There is a DAHDI option for the B410P card to not tell Asterisk that layer
1 went down so Asterisk will allow outgoing calls: "modprobe wcb4xxp
teignored=1".  There is a similar DAHDI option for the HA8 and HB8 cards:
"modprobe wctdm24xxp bri_teignored=1".  Unfortunately that will not clear
up the IRQ misses when the telco brings layer 1 down.

* Add layer 2 persistence option to customize the layer 2 behavior on BRI
PTMP lines.  The new option has three settings: 1) Use libpri default
layer 2 setting.  2) Keep layer 2 up.  Bring layer 2 back up when the peer
brings it down.  3) Leave layer 2 down when the peer brings it down.
Layer 2 will be brought up as needed for outgoing calls.

239f8186ef Problems with ISDN MWI to phones.
1) The "controlling user number" is always the number of the voice mail box
which is identical with the subscriber number itself.  This number which
is listed in the ISDN phone MWI menu cannot be called back to contact the
voice mail box.  The controlling user number should be made configurable.

2) The MWI indication is not restricted to a user (broadcast facility with
dummy call reference).  A called party IE should be added to address only
the relevant MSN.  (ETSI 300-196 Section 8.3.2.4)

e7a5d0da62 B channel lost by incoming call in BRI NT PTMP mode.
A phone's RELEASE_COMPLETE as a response to an initial broadcast SETUP
blocks one B channel permantly when the call is cancelled.

Scenario: A call to the ISDN Bus is acknowledged (ALERTING) by one
phone/endpoint and rejected by another phone/endpoint with a
RELEASE_COMPLETE.  The call is then cancelled by the caller.  If the whole
procedure is repeated once again then any further call attempt is rejected
(WARNING[5666]: app_dial.c:1546 dial_exec_full: Unable to create channel
of type 'DAHDI' (cause 34 - Circuit/channel congestion)).  It seems that
receiving a RELEASE_COMPLETE in that state blocks one B channel
permanently when the call is cancelled by the caller.

Background: The ISDN phones (Siemens Gigaset 3035 or CX253) we use for
testing additionally contain a DECT base station, which operates as a
different endpoint on the ISDN Bus (TEI).  If the DECT base station is not
in use then there are no DECT phones registered to the base station.  The
DECT base station responds to an incoming call not directed toward it with
(RELEASE_COMPLETE, cause: no user responding).

* Made initiate_hangup_if_needed() also hangup the subcall if it is in the
NULL state.

* Simplified q931_set_subcall_winner().

2867fc717e Crash if NFAS swaps D channels on a call with an active timer.
If a Q.931 call record related timer is started on one NFAS D channel
expires after NFAS swaps to another D channel, then libpri could crash.

For example:
1) Hangup a call.
1a) Send a DISCONNECT.
1b) Start the T305 retransmit timer on the current D channel.
2) The RELEASE comes in on another D channel.
2a) The found call record switches its assignment to the new D channel.
2b) Attempt to stop T305.  Unfortunately, the timer was started on another
    D channel so the attempt does not find the timer to stop.
3) The hangup sequence continues normally and the call record is freed
   since there is only one call record pool.
4) T305 expires on the original D channel and crashes the system when it
   uses the stale call record pointer it has saved.

Made each D channel timer pool have a unique range of valid timer
identifiers.  If a given timer identifier is not in the range for the
current NFAS D channel, then search the D channel group for the original D
channel.

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.

33aafe9b5a B410P gets incoming call packets on ISDN but Asterisk doesn't see the call.
The Cisco 1751 with VIC 2-BRI ports sends out SETUP messages on the
broadcast TEI as if the BRI were PTMP even though it is configured for PTP
mode.

Make PTP mode also accept frames on SAPI=0, TEI=127 (Broadcast).

7f55b600e0 Fixes CC agents not automatically clearing if T309 clears the original call.
Incoming calls with CC enabled will not automatically clear the CC offer
record when the call is aborted by T309 processing.  All CC agent FSM's
have this problem (PTMP, PTP, and Q.SIG).

To reproduce:
1) Place incoming call to Asterisk/libpri
2) Either before or after the call is answered, bring the ISDN link down.
3) T309 processing, T309 timeout, or TEI removal will leave the CC agent
FSM in the CC available state.

The problem is indicated by the "cc report status" CLI command showing a
status of CC offered to caller but it will never timeout.

The FSM's can be manually cleared by using the "cc cancel all" or "cc
cancel core" CLI commands.

5923df047d Partial support for dynamic interfaces with NFAS.
To have some support for dynamic interfaces, the master NFAS D channel
control structure will always exist even if it is abandoned/deleted by the
upper layer.  The master/slave pointers ensure that the correct master
will be used.

f9c3c8d026 Extract the layer 2 link structure out of struct pri.
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.

53c142990f Restructure the Q.931 call record to layer 2 link association.
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).

2045db6a69 Segfault in pri_schedule_del() - ctrl value is invalid.
Validate the given call pointer in libpri API calls.  If the call pointer
is not an active call record then a complaint message is issued and the
API call aborts.  The call pointer is likely stale.

This patch is defensive.  More information is needed to figure out why
Asterisk still has a call pointer during its hangup sequence.

384ae1e688 PRI links do not retain active calls if the link comes back before T309 expires.
The DL-ESTABLISH confirm event was not passed from Q.921 to Q.931 so Q.931
never cancelled the T309 timer.

Refactored q931_dl_tei_removal() and q931_dl_indication() into
q931_dl_event() to allow the DL-ESTABLISH confirm/indication and
DL-RELEASE confirm/indication events to be passed to Q.931.
