This commit merges in the rest of the code needed to support distributed device
state. There are two main parts to this commit.
Core changes:
- The device state handling in the core has been updated to understand device
state across a cluster of Asterisk servers. Every time the state of a device
changes, it looks at all of the device states on each node, and determines the
aggregate device state. That resulting device state is what is provided to
modules in Asterisk that take actions based on the state of a device.
New module, res_ais:
- A module has been written to facilitate the communication of events between
nodes in a cluster of Asterisk servers. This module uses the SAForum AIS
(Service Availability Forum Application Interface Specification) CLM and EVT
services (Cluster Management and Event) to handle this task. This module
currently supports sharing Voicemail MWI (Message Waiting Indication) and
device state events between servers. It has been tested with openais, though
other implementations of the spec do exist.
For more information on testing distributed device state, see the following doc:
- doc/distributed_devstate.txt

This commit pulls in a batch of improvements and additions to the event API.
Changes include:
- the ability to dynamically build a subscription. This is useful if you're
building a subscription based on something you receive from the network,
or from options in a configuration file.
- Add tables of event types and IE types and the corresponding string
representation for implementing text based protocols that use these
events, for showing events on the CLI, reading configuration that
references event information, among other things.
- Add a table that maps IE types and the corresponding payload type.
- an API call to get the total size of an event
- an API call to get all events from the cache that match a subscription
- a new IE payload type, raw, which I used for transporting the Entity ID in
my code for handling distributed device state.
- Code improvements to reduce code duplication
- Include the Entity ID of the server that originated the event in every event
- an additional event type, DEVICE_STATE_CHANGE, to help facilitate distributed
device state. DEVICE_STATE is a state change on one server, DEVICE_STATE_CHANGE
is the aggregate device state change across all servers.

This commit breaks out some logic from pbx.c into a simple API. The hint
processing code had logic for taking the state from multiple devices and
turning that into the state for a single extension. So, I broke this out
and made an API that lets you take multiple device states and determine
the aggregate device state. I needed this for some core device state changes
to support distributed device state.

DUNDi uses a concept called the Entity ID for unique server identifiers. I have
pulled out the handling of EIDs and made it something available to all of Asterisk.
There is now a global Entity ID that can be used for other purposes as well, such
as code providing distributed device state, which is why I did this. The global
Entity ID is set automatically, just like it was done in DUNDi, but it can also be
set in asterisk.conf. DUNDi will now use this global EID unless one is specified
in dundi.conf.
The current EID for the system can be seen in the "core show settings" CLI command.
It is also available in the dialplan via the ENTITYID variable.

Reported by: arkadia

These changes:
1. revert the changes made via bug 10668;
I should have known that such changes,
even tho they made sense at the time,
seemed like an omission, etc, were actually
integral to the CDR system via forkCDR.
It makes sense to me now that forkCDR didn't
natively end any CDR's, but rather depended
on natively closing them all at hangup time
via traversing and closing them all, whether
locked or not. I still don't completely
understand the benefits of setvar and answer
operating on locked cdrs, but I've seen
enough to revert those changes also, and
stop messing up users who depended on that
behavior. bug 12726 found reverting the changes
fixed his changes, and after a long review
and working on forkCDR, I can see why.
2. Apply the suggested enhancements proposed
in 10668, but in a completely compatible
way. ForkCDR will behave exactly as before,
but now has new options that will allow some
actions to be taken that will slightly
modify the outcome and side-effects of
forkCDR. Based on conversations I've had
with various people, these small tweaks
will allow some users to get the behavior
they need. For instance, users executing
forkCDR in an AGI script will find the
answer time set, and DISPOSITION set,
a situation not covered when the routines
were first written.
3. A small problem in the cdr serializer
would output answer and end times even
when they were not set. This is now
fixed.

If a deadlock is detected, then the typical lock information will be
printed along with a backtrace of the stack for the offending threads.
Use of this requires compiling with DETECT_DEADLOCKS and having glibc
installed.
Furthermore, issuing the "core show locks" CLI command will print the
normal lock information as well as a backtraces for each lock. This
requires that DEBUG_THREADS is enabled and that glibc is installed.
All the backtrace features may be disabled by running the configure
script with --without-execinfo as an argument

- make data member of the ast_frame struct a named union instead of a void
Recently the ast_queue_hangup function got a new parameter, the hangupcause
Feedback came in that this is no good and that instead a new function should be created.
This I did.
The hangupcause was stored in the seqno member of the ast_frame struct. This is not very
elegant, and since there's already a data member that one should be used.
Problem is, this member was a void *.
Now it's a named union so it can hold a pointer, an uint32 and there's a padding in case someone
wants to store another type in there in the future.
This commit is so massive, because all ast_frame.data uses have to be
altered to ast_frame.data.data
Thanks russellb and kpfleming for the feedback.

a problem if the included file was changed (but not the configuration
file which includes it) and the second source file attempted to reload
the configuration. It would not see that the included file had changed.
In this particular example, res_phoneprov and chan_sip both loaded
sip.conf, which included a file call sip.peers.conf. Since res_phoneprov
was the first to load sip.conf, only it cached the fact that sip.conf
included sip.peers.conf. If sip.peers.conf were changed and sip.conf were
not and a sip reload were issued (meaning that chan_sip attempts to
reload sip.conf only if it and its included files have changed) the changes
made to sip.peers.conf would not be seen and therefore no action would be
taken.
