Make sorcery details opaque and add extended fields.
Sorcery specific object information is now opaque and allocated with the object.
This means that modules do not need to be recompiled if the sorcery specific part
is changed. It also means that sorcery can store additional information on objects
and ensure it is freed or the reference count decreased when the object goes away.
To facilitate the above a generic sorcery allocator function has been added which
also ensures that allocated objects do not have a lock.
Extended fields have been added thanks to all of the above which allows specific fields
to be marked as extended, and thus simply stored as-is within the object. Type safety
is *NOT* enforced on these fields. A consumer of them has to query and ultimately perform
their own safety check. What does this mean? Extra modules can extend already defined
structures without having to modify them.

Fix a deadlock and possible crash in res_fax
This patch fixes two bugs.
(1) It unlocks the channel in the framehook handlers before attempting to grab
the peer from the bridge. The locking order for the bridging framework is
bridge first, then channel - having the channel locked while attempting to
obtain the bridge lock causes a locking inversion and a deadlock. This
patch bumps the channel ref count prior to releasing the lock in the
framehook to avoid lifetime issues.
Note that this does expose a subtle problem in framehooks; that is,
something could modify the framehook list while we are executing, causing
issues in the framehook list traversal that the callback executes in.
Fixing this is a much larger problem that is beyond the scope of this
patch - (a) we already unlock the channel in this particular framehook
and we haven't run into a problem yet (as modifying the framehook list
when a channel is about to perform a fax gateway would be a very odd
operation) and (b) migrating to an ao2 container of framehooks would be
more invasive at this point. See the referenced ASTERISK issue for more
information.
(2) Directly packing channel variables into a JSON object turned out to be
unsafe. A condition existed where the strings in the JSON blob were no
longer safe to be accessed if the channel object itself was disposed of.

When a threadpool is set to autoincrement its threadcount, an issue

Prevent sending a NewExten event after a Hangup during a stack restore
When a channel is originated, its application is typically set to AppDial2,
indicating that it was a dialed channel through the Dial API. Asterisk during
an originate will perform a stack execute to direct the outgoing channel to
a particular place in the dialplan or application. When the stack returns, the
previous application (AppDial2) is restored.
Unfortunately, in the case of an originated channel, the stack restore happens
after hangup. A stasis message is sent notifying everyone that the application
was restored, and this causes a NewExten event to go out after the Hangup event,
violating the basic contract consumers have of the channel lifetime. While we
could preclude the message from going out, restoring the channel's state before
it executed the next higher frame in the stack has to occur, and other places
in the code depend on this behavior.

to see if the channel has been zombified before sending a NewExten event.

Update Asterisk's CDRs for the new bridging framework
This patch is the initial push to update Asterisk's CDR engine for the new
bridging framework. This patch guts the existing CDR engine and builds the new
on top of messages coming across Stasis. As changes in channel state and bridge
state are detected, CDRs are built and dispatched accordingly. This
fundamentally changes CDRs in a few ways.
(1) CDRs are now *very* reflective of the actual state of channels and bridges.
This means CDRs track well with what an actual channel is doing - which
is useful in transfer scenarios (which were previously difficult to pin
down). It does, however, mean that CDRs cannot be 'fooled'. Previous
behavior in Asterisk allowed for CDR applications, channels, and other
properties to be spoofed in parts of the code - this no longer works.
(2) CDRs have defined behavior in multi-party scenarios. This behavior will not
be what everyone wants, but it is a defined behavior and as such, it is
predictable.
(3) The CDR manipulation functions and applications have been overhauled. Major
changes have been made to ResetCDR and ForkCDR in particular. Many of the
options for these two applications no longer made any sense with the new
framework and the (slightly) more immutable nature of CDRs.
There are a plethora of other changes. For a full description of CDR behavior,

Reimplement bridging and DTMF features related channel variables in the bridging core.
* The channel variable ATTENDED_TRANSFER_COMPLETE_SOUND is no longer
channel driver specific. If the channel variable is set on the
transferrer channel, the sound will be played to the target of an attended
transfer.
* The channel variable BRIDGEPEER becomes a comma separated list of peers
in a multi-party bridge. The BRIDGEPEER value can have a maximum of 10
peers listed. Any more peers in the bridge will not be included in the
list. BRIDGEPEER is not valid in holding bridges like parking since those
channels do not talk to each other even though they are in a bridge.
* The channel variable BRIDGEPVTCALLID is only valid for two party bridges
and will contain a value if the BRIDGEPEER's channel driver supports it.
* The channel variable DYNAMIC_PEERNAME is redundant with BRIDGEPEER and
is removed. The more useful DYNAMIC_WHO_ACTIVATED gives the channel name
that activated the dynamic feature.
* The channel variables DYNAMIC_FEATURENAME and DYNAMIC_WHO_ACTIVATED are
set only on the channel executing the dynamic feature. Executing a
dynamic feature on the bridge peer in a multi-party bridge will execute it
on all peers of the activating channel.

Refactor the features configuration scheme.
Features configuration is handled in its own API in
features_config.h and features_config.c. This way, features
configuration is accessible to anything that needs it.
In addition, features configuration has been altered to
be more channel-oriented. Most callers of features API
code will be supplying a channel so that the individual
channel's settings will be acquired rather than the global
setting.
Missing from this commit is XML documentation for the
features configuration. That will be handled in a separate
commit.
