The current TCP client connect code, blocks and does not handle EINTR
error case.

This patch makes the client socket non-blocking while connecting,
ensures a connect does not immediately fail due to EINTR "errors",
and adds a connect timeout option.

The original client start call sets the new timeout option to
"infinite", thus making sure old, orginal behavior is retained.

A previous patch for ASTERISK_29578 caused a 'leak' of
extension state information across queues, causing the
state of the first member of unrelated queues to be
updated in addition to the correct member. Which queues
and members depended on the order of queues in the
iterator.

Additionally, it is possible to use the same 'hint:' on
multiple queue members, so the update cannot break out
of the update loop early when a match is found.

The ast_rtp_codecs_payloads functions do not preserve the order in which
the payloads were specified on an incoming SDP media line. This leads to
a problem with the codec negotiation functionality, as the format
capabilities of the stream are extracted from the ast_rtp_codecs. This
commit moves the ast_rtp_codec to ast_format conversion to the place
where the order is still known.

Instead of having the test fail when this happens, report the

sip_inv:  Additional multipart support (#2919)

sip_inv.c:inv_check_sdp_in_incoming_msg() deals with multipart
message bodies in rdata correctly. In the case where early media is
involved though, the existing sdp has to be retrieved from the last
tdata sent in this transaction. This, however, always assumes that
the sdp sent is in a non-multipart body. While there's a function
to retrieve the sdp from multipart and non-multpart rdata bodies,
no similar function for tdata exists.  So...

* The existing pjsip_rdata_get_sdp_info2 was refactored to
  find the sdp in any body, multipart or non-multipart, and
  from either an rdata or tdata.  The new function is
  pjsip_get_sdp_info.  This new function detects whether the
  pjsip_msg->body->data is the text representation of the sdp
  from an rdata or an existing pjmedia_sdp_session object
  from a tdata, or whether pjsip_msg->body is a multipart
  body containing either of the two sdp formats.

* The exsting pjsip_rdata_get_sdp_info and pjsip_rdata_get_sdp_info2
  functions are now wrappers that get the body and Content-Type
  header from the rdata and call pjsip_get_sdp_info.

* Two new wrappers named pjsip_tdata_get_sdp_info and
  pjsip_tdata_get_sdp_info2 have been created that get the body
  from the tdata and call pjsip_get_sdp_info.

* inv_offer_answer_test.c was updated to test multipart scenarios.

Previously, it was only possible to have one HTTP server in Asterisk.
With this patch it is now possible to have multiple HTTP servers
listening on different addresses.

Note, this behavior has only been made available through an API call
from within the TEST_FRAMEWORK. Specifically, this feature has been
added in order to allow unit test to create/start and stop servers,
if one has not been enabled through configuration.

Currently, Asterisk doesn't throw warnings if options
are passed into applications that don't accept them.
This can confuse users if they're unaware that they
are doing something wrong.

This adds an additional check to parse_options so that
a warning is thrown anytime an option is parsed that
doesn't exist in the parsing application, so that users
are notified of the invalid usage.

Includes some minor updates to extensions.conf
and iax.conf. In particular, the demonstration
of macros in extensions.conf is removed, as
Macro is deprecated and will be removed soon.
These examples have been replaced with examples
demonstrating the usage of Gosub instead.

The older exten => ...,n syntax is also mostly
replaced with the same keyword to demonstrate the
newer, more concise way of defining extensions.

IAXTEL no longer exists, so this example is replaced
with something more generic.

Some documentation is also added to extensions.conf
and iax.conf to clarify some of the new expanded
encryption capabilities with IAX2.

conjunction with SendText. Currently, there is no

Currently MSet can only parse a maximum of 24 variables.
If more variables are provided to MSet, the 24th variable
will simply contain the remainder of the string and the
remaining variables thereafter will never get set.

This increases the number of variables that can be parsed
in one go from 24 to 99. Additionally, documentation is added
since this limitation is currently undocumented and is
confusing to users who encounter this limitation.

Attempting to access ${CHANNEL(ruri)} in a pre-dial handler before
initiating an outgoing call will cause Asterisk to crash. This is
because a null field is accessed, resulting in an offset from null and
subsequent memory access violation.

Since RURI is not guaranteed to exist, we now check if the base
pointer is non-null before calculating an offset.

Adds the JSON_DECODE function for parsing JSON in the

with CURL for using API responses.

Currently, variable substitution involving dialplan
extensions is quite clunky since it entails obtaining
the current dialplan location, backing it up, storing
the desired variables for substitution on the channel,
performing substitution, then restoring the original
location.

In addition to being clunky, things could also go wrong
if an async goto were to occur and change the dialplan
location during a substitution.

Fundamentally, there's no reason it needs to be done this
way, so new API is added to allow for directly passing in
the dialplan location for the purposes of variable
substitution so we don't need to mess with the channel
information anymore. Existing API is not changed.

In noisy mode, output all possible warnings of Doxygen.
This creates zillion of warnings. Double-check your current module!

Any warnings are in the file './doxygen.log'. Beside that, this change
avoids deprecated parameters because the configuration file for Doxygen
contains only those parameters which differ from the default. This
avoids the need to update the file on each run. Furthermore, it adds
AST_VECTOR to be expanded. Finally, the default name for that file is
