adds the datastore to the session. The header is then created as a pjsip_hdr
and added to the list. An outgoing supplemental session callback then
traverses the list and adds the headers to the outgoing pjsip_msg.

Remove dispatch object allocation from Stasis publishing
While looking for areas for performance improvement, I realized that an
unused feature in Stasis was negatively impacting performance.
When a message is sent to a subscriber, a dispatch object is allocated
for the dispatch, containing the topic the message was published to, the
subscriber the message is being sent to, and the message itself.
The topic is actually unused by any subscriber in Asterisk today. And
the subscriber is associated with the taskprocessor the message is being
dispatched to.
First, this patch removes the unused topic parameter from Stasis
subscription callbacks.
Second, this patch introduces the concept of taskprocessor local data,
data that may be set on a taskprocessor and provided along with the data
pointer when a task is pushed using the ast_taskprocessor_push_local()
call. This allows the task to have both data specific to that
taskprocessor, in addition to data specific to that invocation.
With those two changes, the dispatch object can be removed completely,
and the message is simply refcounted and sent directly to the
taskprocessor.

Optimize how Stasis forwards are dispatched
This patch optimizes how forwards are dispatched in Stasis.
Originally, forwards were dispatched as subscriptions that are invoked
on the publishing thread. This did not account for the vast number of
forwards we would end up having in the system, and the amount of work it
would take to walk though the forward subscriptions.
This patch modifies Stasis so that rather than walking the tree of
forwards on every dispatch, when forwards and subscriptions are changed,
the subscriber list for every topic in the tree is changed.
This has a couple of benefits. First, this reduces the workload of
dispatching messages. It also reduces contention when dispatching to
different topics that happen to forward to the same aggregation topic
(as happens with all of the channel, bridge and endpoint topics).
Since forwards are no longer subscriptions, the bulk of this patch is
simply changing stasis_subscription objects to stasis_forward objects
(which, admittedly, I should have done in the first place.)
Since this required me to yet again put in a growing array, I finally
abstracted that out into a set of ast_vector macros in

The taskprocessor execution was also slightly optimized to reduce the
number of locks taken.
The only observable difference in the taskprocessor implementation is
that when the final reference to the taskprocessor goes away, it will
execute all tasks to completion instead of discarding the unexecuted
tasks.
For systems where unnamed semaphores are not supported, a really
simple semaphore implementation is provided. (Which gives identical
performance as the original taskprocessor implementation).
The way we ended up implementing Stasis caused the threadpool to be a
burden instead of a boost to performance. This was switched to just

res_rtp_asterisk: Correct erroneous lost packet information in RTCP reports
RTCP's calculation of the number of lost packets in an RTP stream is based on
that stream's sequence number count, the number of received packets, and how
many packets we expect to receive. When the SSRC for an RTP stream changes,
there can - and almost always will be - a large jump in the next packet's
timestamp and sequence number. If we don't reset the number of received
packets, sequence number count, and other metrics used by RTCP, the next RR/SR
report will use the previous SSRC's values to calculate the lost packet count
for the new SSRC - resulting in a very large number of lost packets.
This patch modifies res_rtp_asterisk such that, if it detects a SSRC change, it
will reset the various values used by the RTCP calculations. From the

Add check for openSUSE when detecting bfd library
In ASTERISK-17842, some additional library checks were added to the configure
script so that the bfd library could be found on CentOS and Fedora systems.
As it turns out, openSUSE requires an additional library. This patch adds
another check to the configure script for openSUSE that will add that library.

CDR: Improve handling of parking; resolve assertion when originating into park
This patch covers two problems:
1) Currently, when a call is transferred into a parking lot from a bridge
(using either the blind transfer or one touch parking mechanisms), the
application fails to be set to "Park" in the resulting CDR record for
the parked channel. This is due to the ParkedCall message arriving before
the BridgeEnter for the channel entering the parking bridge. The ParkedCall
message isn't handled as the CDR for the channel has already been finalized
(due to the channel having left its two party bridge), and the BridgeEnter -
which creates the new CDR - doesn't have the parking information. This patch
modifies the behavior so that reception of a ParkedCall message will - if
not handled by a CDR chain - cause a new CDR to be created and put into the
Parking state.
2) It fixes a FRACK that occurred when a channel is originated into a parking
space. The DialedPending state - which occurs for both Dialed and Originated
channels - assumed that it couldn't handle the parking transitions due to it
having a Party B; however, Originated channels don't have a Party B. As such,
the existing CDR needs to transition into the parking state - this patch does
that.

app_queue: Make manager events tolerant of Local channel shenanigans
app_queue currently attempts to handle Local channel optimizations in an effort
to provide accurate information in Stasis messages (and their corresponding
AMI events) as well as the Queue log. Sometimes, however, things don't go as
planned.
Consider the following scenario:
SIP/foo <-> L;1 <-> L;2 <-> SIP/agent
SIP/agent answers, triggering a Local channel optimization. app_queue will
normally do the following:
* Listen for the Local optimization events and update our agent accordingly
to SIP/agent in the queue log and messages
* When we get a hangup, publish the AgentComplete event based on our
information (SIP/foo and SIP/agent)
However, as with all things that depend on sanity from something as capricious
as Local channels, things can go wrong:
(1) SIP/agent immediately hangs up upon answering. This triggers a race
condition between termination messages coming from SIP/agent and the
ongoing Local channel optimization messages. (Note that this can also
occur with SIP/foo)
(2) In a race condition, Asterisk can (rarely) deliver the hangup messages
prior to the Local channel optimization.
In that case, the messages *may* arrive to app_queue in the following order:
* Hangup SIP/Agent
* Hangup SIP/foo
* Optimize L;1/L;2
* Hangup L;2
* Hangup L;1
When app_queue receives the hangup of the agent or the caller, it will attempt
to publish the AgentComplete event. However, it now has a problem - it thinks
its agent is the ;1 side of the Local channel, as it never received the
optimization event. At the same time, that channel is already gone. This
results in getting NULL from the Stasis cache. What's more, we can't really
wait for the optimization message, as we are currently handling the hangup
of the channel that the optimization event would tell us to use.
This patch modifies the behavior in app_queue such that, since we still have a
lot of pertinent queue information (interface, queue name, etc.), we now raise
the event with what information we know. The channels involved now may or may
not be present. Users will still at least get the "AgentComplete" event, which
"completes" the known Agent information.

manager: Fix crash when appending a manager channel variable
In r399887, a minor performance improvement was introduced by not allocating
the manager variable struct if it wasn't used. Unfortunately, when directly
accessing an ast_channel struct, manager assumed that the struct was always
allocated. Since this was no longer the case, things got a bit crashy.
This fixes that problem by simply bypassing appending variables if the manager
channel variable struct isn't there.

res_pjsip: crash when using localnet and external_signaling_address options
There was a collision of mod_data use on the transaction between using a nat
hook and an session response callback. During state change it was assumed
what was in the mod_data was nothing or the response callback. However, it
was possible for it to also contain a nat hook thus resulting in a bad cast
and a crash.
Added the ability to store multiple data elements in mod_data via a hash table.
In this instance, mod_data now stores a hash table of the two values that can
be retrieved using an associated string key.

chan_sip: Reject calls on 200 OKs if no SDP has been received
When Asterisk receives a 200 OK in response to an invite, that peer should have
sent an SDP at some point by then. If the channel has never received an SDP,
media won't have been set and the remote address won't be known. Endpoints in
general should not be doing this. This patch makes it so that Asterisk will
simply hang up a call if it sends a 200 OK at this point. So far this odd
behavior for endpoints has only been observed in tests which involved manually
created SIP transactions in SIPp.

astobj2: Remove OBJ_CONTINUE support.
OBJ_CONTINUE was a strange feature that came into the world under
suspicious circumstances to support an abuse of the ao2_container by
chan_iax2. Since chan_iax2 no longer uses OBJ_CONTINUE, it is safe to
remove it.
The simplified code should help performance slightly and make
understanding the code easier.

Fix refleaks of ast_rtp_instance structures.
These refleaks were causing bridged calls not to close their RTP ports. Thus
a call would leave open 4 ports (RTP for party A, RTCP for party A, RTP for party
B, and RTCP for party B). This led to an eventual depletion of available RTP
ports.

Restore usefulness of the CEL Peer field
This change makes the CEL peer field useful again for BRIDGE_ENTER and
BRIDGE_EXIT events and fills the field with a comma-separated list of
all channels in the bridge other than the channel that is entering or
exiting the bridge.
