When asterisk generates the RLMI part of NOTIFY request,
the asterisk uses the local contact uri instead of the URI to which
the SUBSCRIBE request is sent.
Because of this mismatch some IP phones (for example Cisco 5XX) ignore
this list.

According
https://datatracker.ietf.org/doc/html/rfc4662#section-5.2
  The first mandatory <list> attribute is "uri", which contains the uri
  that corresponds to the list. Typically, this is the URI to which
  the SUBSCRIBE request was sent.
https://datatracker.ietf.org/doc/html/rfc4662#section-5.3
  The "uri" attribute identifies the resource to which the <resource>
  element corresponds. Typically, this will be a SIP URI that, if
  subscribed to, would return the state of the resource.

This patch makes asterisk to generate URI using SUBSCRIBE request URI.

This AMI action makes it possible to withdraw a caller from a queue,
in a safe and a generic manner.
This can be useful for retrieving a specific call and

whenever it can. Therefore, it is not guaranteed
that the call will leave the queue.

Moved the xmldoc build logic from the top-level Makefile into
its own script "make_xml_documentation" in the build_tools
directory.

Created a new utility script "get_sourceable_makeopts", also in
the build_tools directory, that dumps the top-level "makeopts"
file in a format that can be "sourced" from shell sscripts.
This allows scripts to easily get the values of common make
build variables such as the location of the GREP, SED, AWK, etc.
utilities as well as the AST* and library *_LIB and *_INCLUDE
variables.

Besides moving logic out of the Makefile, some optimizations
were done like removing "third-party" from the list of
subdirectories to be searched for documentation and changing some
assignments from "=" to ":=" so they're only evaluated once.
The speed increase is noticeable.

The makeopts.in file was updated to include the paths to
REALPATH and DIRNAME.  The ./conifgure script was setting them
but makeopts.in wasn't including them.

So...

With this change, you can now place documentation in any"c"
source file AND you can now place it in a separate XML file
altogether.  The following are examples of valid locations:

res/res_pjsip.c
    Using the existing /*** DOCUMENTATION ***/ fragment.

res/res_pjsip/pjsip_configuration.c
    Using the existing /*** DOCUMENTATION ***/ fragment.

res/res_pjsip/pjsip_doc.xml
    A fully-formed XML file.  The "configInfo", "manager",
    "managerEvent", etc. elements that would be in the "c"
    file DOCUMENTATION fragment should be wrapped in proper
    XML.  Example for "somemodule.xml":

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE docs SYSTEM "appdocsxml.dtd">
    <docs>
        <configInfo>
        ...
        </configInfo>
    </docs>

It's the "appdocsxml.dtd" that tells make_xml_documentation
that this is a documentation XML file and not some other XML file.
It also allows many XML-capable editors to do formatting and
validation.

Other than the ".xml" suffix, the name of the file is not
significant.

As a start... This change also moves the documentation that was
in res_pjsip.c to 2 new XML files in res/res_pjsip:
pjsip_config.xml and pjsip_manager.xml.  This cut the number of
lines in res_pjsip.c in half. :)

Recap from earlier commit:  If you have a development branch for a
major project that will receive gerrit reviews it'll probably be
named something like "development/16/newproject" or a work branch
based on that "development" branch.  That will necessitate
setting "defaultbranch=development/16/newproject" in .gitreview.
The make_version script uses that variable to construct the
asterisk version however, which results in versions
like "GIT-development/16/newproject-ee582a8c7b" which is probably
not what you want.  It also constructs the URLs for downloading
external modules with that version, which will fail.

Fast-forward:

The earlier attempt at adding a "basebranch" variable to
.gitreview didn't work out too well in practice because changes
were made to .gitreview, which is a checked-in file.  So, if
you wanted to rebase your work branch on the base branch, rebase
would attempt to overwrite your .gitreview with the one from
the base branch and complain about a conflict.

This is a slighltly different approach that adds three methods to
determine the mainline branch:

1.  --- MAINLINE_BRANCH from the environment

If MAINLINE_BRANCH is already set in the environment, that will
be used.  This is primarily for the Jenkins jobs.

2.  --- .develvars

Instead of storing the basebranch in .gitreview, it can now be
stored in a non-checked-in ".develvars" file and keyed by the
current branch.  So, if you were working on a branch named
"new-feature-work" based on "development/16/new-feature" and wanted
 to push to that branch in Gerrit but wanted to pull the external
 modules for 16, you'd create the following .develvars file:

[branch "new-feature-work"]
    mainline-branch = 16

The .gitreview file would still look like:

[gerrit]
defaultbranch=development/16/new-feature

...which would cause any reviews pushed from "new-feature-work" to
go to the "development/16/new-feature" branch in Gerrit.

The key is that the .develvars file is NEVER checked in (it's been
added to .gitignore).

3.  --- Well Known Development Branch

If you're actually working in a branch named like
"development/<mainline_branch>/some-feature", the mainline branch
will be parsed from it.

4.  --- .gitreview

If none of the earlier conditions exist, the .gitreview
"defaultbranch" variable will be used just as before.

Although there are 10 debugs levels, over time,
many current debug calls have come to use
inappropriately low debug levels. In particular,
a select few debug calls (currently all debug 1)
can result in thousands of debug messages per minute
for a single call.

This can adds a lot of noise to core debug
which dilutes the value in having different
debug levels in the first place, as these
log messages are from the core internals are
are better suited for higher debug levels.

Some debugs levels are thus adjusted so that
debug level 1 is not inappropriately overloaded
with these extremely high-volume and general
debug messages.

Adds the since tag to the documentation DTD so
that individual applications, functions, etc.
can now specify when they were added to Asterisk.

This tag is added at the individual application,
function, etc. level as opposed to at the module
level because modules can expand over time as new
functionality is added, and granularity only
to the module level would generally not be useful.

This enables the ability to more easily determine
when new functionality was added to Asterisk, down
to minor version as opposed to just by major version.
This makes it easier for users to write more portable
dialplan if desired to not use functionality that may
not be widely available yet.

to prompting the user for the mailbox, as if no arguments were

then no warning at all is emitted.

If Subscription refresh occurred between when the batched notification
was scheduled and the serialized notification was to be sent,
then new schedule notification task would never be added.

There are 2 threads:

thread #1. ast_sip_subscription_notify is called,
if notification_batch_interval then call schedule_notification.
1.1. The schedule_notification checks notify_sched_id > -1
not true, then
send_scheduled_notify = 1
notify_sched_id =
  ast_sched_add(sched, sub_tree->notification_batch_interval, sched_cb....
1.2. The sched_cb pushes task serialized_send_notify to serializer
and returns 0 which means no reschedule.
1.3. The serialized_send_notify checks send_scheduled_notify if it's false
the just returns. BUT notify_sched_id is still set, so no more ast_sched_add.

thread #2. pubsub_on_rx_refresh is called
2.1 it pushes serialized_pubsub_on_refresh_timeout to serializer
2.2. The serialized_pubsub_on_refresh_timeout calls pubsub_on_refresh_timeout
which calls send_notify
2.3. The send_notify set send_scheduled_notify = 0;

The serialized_send_notify should always unset notify_sched_id.

Adds an option to the ReceiveMF application to allow specifying a
maximum number of digits.

Originally, this capability was not added to ReceiveMF as it was
with ReceiveSF because typically a ST digit is used to denote that
sending of digits is complete. However, there are certain signaling
protocols which simply transmit a digit (such as Expanded In-Band
Signaling) and for these, it's necessary to be able to read a
certain number of digits, as opposed to until receiving a ST digit.

This capability is added as an option, as opposed to as a parameter,
to remain compatible with existing usage (and not shift the
parameters).
