When determining if codecs used by SIP peers allow
the media to be natively bridged, use the jointcapability
instead of the peercapability.
It seems that the intent of using the peercapability was to
expand the choice of codecs for the call to increase the
chances of being able to native bridge the channels. The
problem is that if a codec were settled on for the native
bridge and that wasn't a codec that was configured to be used
by Asterisk for that peer, then Asterisk would send a
REINVITE with no codecs in the SDP which is a bug no matter
how you slice it.

Commit 140417 had a logic flaw in it which
caused port 5060 to always be used when dialing
a peer if no explicit port was specified. This
broke the behavior of implicitly using the port
from which the peer registered if no port is
specified. This commit fixes the logic flaw.
If you find this message overly verbose, relax, it's probably
not meant for you. This message is meant for probably only
two people in the whole world: me, or the poor schnook that
has to maintain this code because I'm either dead or unavailable
at the moment.
This fix solves two reports, both having to do with embedding
a function call in a ${} construct. It was tricky because the
funccall syntax has parenthesis () in it. And up till now,
the 'word' token in the flex stuff didn't allow that, because
it would tend to steal the LP and RP tokens. To be truthful,
the "word" token was the trickiest, most unstable thing in
the whole lexer. I was lucky it made this long without complaints.
I had to choose every character in the pattern with extreme
care, and I knew that someday I'd have to revisit it. Well,
the day has come.
So, my brilliant idea (and I'm being modest), was to use the
surrounding ${} construct to make a state machine and capture
everything in it, no matter what it contains. But, I have to now
treat the word token like I did with comments, in that I turn
the whole thing into a state-machine sort of spec, with new
contexts "curlystate", "wordstate", and "brackstate".
Wait a minute, "brackstate"? Yes, well, it didn't take very many
regression tests to point out if I do this for ${} constructs,
I also have to do it with the $[] constructs, too.
I had to create a separate pcbstack2 and pcbstack3 because
these constructs can occur inside macro argument lists, and
when we have two state machines operating on the same structures
we'd get problems otherwise. I guess I could have stopped at
pcbstack2 and had the brackstate stuff share it, but it doesn't
hurt to be safe. So, the pcbpush and pcbpop routines also now
have versions for "2" and "3".
I had to add the {KEYWORD} construct to the initial pattern for
"word", because previously word would match stuff like "default7",
because it was a longer match than the keyword "default". But,
not any more, because the word pattern only matches only one or
two characters now, and it will always lose. So, I made it the
winner again by making an optional match on any of the keywords
before it's normal pattern.
I added another regression test to make sure we don't
lose this in future edits, and had to fix just one regression,
where it no longer reports a 'cascaded' error, which I guess
is a plus.
I've given some thought as to whether to apply these fixes to
1.4 and the 1.6.x releases, vs trunk; I decided to put it in
1.4 because one of the bug reports was against 1.4; and it
is unexpected that AEL cannot handle this situation. It actually
reduced the amount of useless "cascade" error messages that
appeared in the regressions (by one line, ehhem). There is
a possible side-effect in that it does now do more careful
checking of what's in those ${} constructs, as far as matching
parens, and brackets are concerned. Some users may find a an
insidious problem and correct it this way. This should be
exceedingly rare, I hope.

After working on the ao2_containers branch, I noticed
something a bit strange. In all cases where we provide
a callback function to ao2_container_alloc, the callback
function would only return 0 or CMP_MATCH. After inspecting
the ao2_callback() code carefully, I found that if you're
only looking for one specific item, then you should return
CMP_MATCH | CMP_STOP. Otherwise, astobj2 will continue
traversing the current bucket until the end searching for
more matches.
In cases like chan_iax2 where in 1.4, all the peers are
shoved into a single bucket, this makes for potentially
terrible performance since the entire bucket will be
traversed even if the peer is one of the first ones come
across in the bucket.
All the changes I have made were for cases where the
callback function defined was passed to ao2_container_alloc
so that calls to ao2_find could find a unique instance
of whatever object was being stored in the container.

Remove show_frame_stats_deprecated since it is not
used anywhere and causes build errors if building under
dev-mode with TRACE_FRAMES selected in menuselect.
THis is a bold move for a static release fix, but I wouldn't have
made it if I didn't feel confident (at least a *bit* confident)
that it wouldn't mess everyone up.
The reasoning goes something like this:
1. We simply cannot do anything with CDR's at the current point
(in pbx.c, after the __ast_pbx_run loop). It's way too late to
have any affect on the CDRs. The CDR is already posted and gone,
and the remnants have been cleared.
2. I was very much afraid that moving the running of the 'h'
extension down into the bridge code (where it would be now
practical to do it), would result in a lot more calls to the
'h' exten, so I implemented it as another exten under another
name, but found, to my pleasant surprise, that there was a
1:1 correspondence to the running of the 'h' exten in the
pbx_run loop, and the new spot at the end of the bridge.
So, I ifdef'd out the current 'h' loop, and moved it into
the bridge code. The only difference I can see is the stuff
about the AST_PBX_KEEPALIVE, and hopefully, if this
is still an important decision point, I can replicate it
if there are complaints. To be perfectly honest,
the KEEPALIVE situation is not totally clear to me,
and how it relates to a post-bridge situation is less
clear. I suspect the users will point out everything
in total clarity if this steps on anyone's toes!
3. I temporarily swap the bridge_cdr into the channel
before running the 'h' exten, which makes it possible
for users to edit the cdr before it goes out the door.
And, of course, with the endbeforehexten config var set,
the users can also get at the billsec/duration vals.
After the h exten finishes, the cdr is swapped back
and processing continues as normal.
Please, all who deal with CDR's, please test this version
of Asterisk, and file bug reports as appropriate!

Add a lock and unlock prior to the destruction of the chanspy_ds
lock to ensure that no other threads still have it locked. While
this should not happen under normal circumstances, it appears that
if the spyer and spyee hang up at nearly the same time, the following
may occur.
1. ast_channel_free is called on the spyee's channel.
2. The chanspy datastore is removed from the spyee's channel in
ast_channel_free.
3. In the spyer's thread, the spyer attempts to remove and destroy the datastore
from the spyee channel, but the datastore has already been removed in step 2,
so the spyer continues in the code.
4. The spyee's thread continues and calls the datastore's destroy callback,
chanspy_ds_destroy. This involves locking the chanspy_ds.
5. Now the spyer attempts to destroy the chanspy_ds lock. The problem is that in step 4,
the spyee has locked this lock, meaning that the spyer is attempting to destroy a lock
which is currently locked by another thread.
