a96e42c326 .github: Refactor to use pull_request_target trigger.
After careful review, we believe we can now use the "pull_request_target"
workflow trigger instead of "pull_request" which required a separate
privliged workflow to add labels and comments to PRs when they are submitted
or updated.  This allows us to greatly streamline our workflows and remove
unneeded ones.

* The OnPRChanged workflow was...
  * Renamed to OnPRCheck
  * Changed to trigger on pull_request_target and the "recheckpr" label.
  * Changed to simply call reusable workflows in asterisk-ci-actions.
  * Changed to use better concurrency groups.
* The OnPRCPCheck and OnPRMergeApproved workflows were also...
  * Changed to simply call reusable workflows in asterisk-ci-actions.
  * Changed to use better concurrency groups.
* The NightlyTest and CreateDocs were also tweaked

a5b92988f2 res_stir_shaken: Allow missing or anonymous CID to continue to the dialplan.
The verification check for missing or anonymous callerid was happening before
the endpoint's profile was retrieved which meant that the failure_action
parameter wasn't available.  Therefore, if verification was enabled and there
was no callerid or it was "anonymous", the call was immediately terminated
instead of giving the dialplan the ability to decide what to do with the call.

* The callerid check now happens after the verification context is created and
  the endpoint's stir_shaken_profile is available.

* The check now processes the callerid failure just as it does for other
  verification failures and respects the failure_action parameter.  If set
  to "continue" or "continue_return_reason", `STIR_SHAKEN(0,verify_result)`
  in the dialplan will return "invalid_or_no_callerid".

* If the endpoint's failure_action is "reject_request", the call will be
  rejected with `433 "Anonymity Disallowed"`.

* If the endpoint's failure_action is "continue_return_reason", the call will
  continue but a `Reason: STIR; cause=433; text="Anonymity Disallowed"`
  header will be added to the next provisional or final response.

762c0187e1 resource_channels.c: Fix memory leak in ast_ari_channels_external_media.
Between ast_ari_channels_external_media(), external_media_rtp_udp(),
and external_media_audiosocket_tcp(), the `variables` structure being passed
around wasn't being cleaned up properly when there was a failure.

* In ast_ari_channels_external_media(), the `variables` structure is now
  defined with RAII_VAR to ensure it always gets cleaned up.

* The ast_variables_destroy() call was removed from external_media_rtp_udp().

* The ast_variables_destroy() call was removed from
  external_media_audiosocket_tcp(), its `endpoint` allocation was changed to
  to use ast_asprintf() as external_media_rtp_udp() does, and it now
  returns an error on failure.

* ast_ari_channels_external_media() now checks the new return code from
  external_media_audiosocket_tcp() and sets the appropriate error response.

0e8bde6bde ari/pjsip: Make it possible to control transfers through ARI
Introduce a ChannelTransfer event and the ability to notify progress to
ARI. Implement emitting this event from the PJSIP channel instead of
handling the transfer in Asterisk when configured.

Introduce a dialplan function to the PJSIP channel to switch between the
"core" and "ari-only" behavior.

UserNote: Call transfers on the PJSIP channel can now be controlled by
ARI. This can be enabled by using the PJSIP_TRANSFER_HANDLING(ari-only)
dialplan function.

2ab3117e0c channel.c: Remove dead AST_GENERATOR_FD code.
Nothing ever sets the `AST_GENERATOR_FD`, so this block of code will
never execute. It also is the only place where the `generate` callback
is called with the channel lock held which made it difficult to reason
about the thread safety of `ast_generator`s.

In passing, also note that `AST_AGENT_FD` isn't used either.

When in single-argument mode (very rarely used), a malformation of a column

16480d6e73 docs: Add version information to AGI command XML elements.
This process was a bit different than the others because everything
is in the same file, there's an array that contains the command
names and their handler functions, and the last command was created
over 15 years ago.

* Dump a `git blame` of res/res_agi.c from BEFORE the handle_* prototypes
  were changed.
* Create a command <> handler function xref by parsing the the agi_command
  array.
* For each entry, grep the function definition line "static int handle_*"
  from the git blame output and capture the commit.  This will be the
  commit the command was created in.
* Do a `git tag --contains <commit> | sort -V | head -1` to get the
  tag the function was created in.
* Add a single since/version element to the command XML.  Multiple versions
  aren't supported here because the branching and tagging scheme changed
  several times in the 2000's.

efd813165c res_pjsip_authenticator_digest: Make correct error messages appear again.
When an incoming request can't be matched to an endpoint, the "artificial"
auth object is used to create a challenge to return in a 401 response and we
emit a "No matching endpoint found" log message. If the client then responds
with an Authorization header but the request still can't be matched to an
endpoint, the verification will fail and, as before, we'll create a challenge
to return in a 401 response and we emit a "No matching endpoint found" log
message.  HOWEVER, because there WAS an Authorization header and it failed
verification, we should have also been emitting a "Failed to authenticate"
log message but weren't because there was a check that short-circuited that
it if the artificial auth was used.  Since many admins use the "Failed to
authenticate" message with log parsers like fail2ban, those attempts were not
being recognized as suspicious.

Changes:

* digest_check_auth() now always emits the "Failed to authenticate" log
  message if verification of an Authorization header failed even if the
  artificial auth was used.

* The verification logic was refactored to be clearer about the handling
  of the return codes from verify().

* Comments were added clarify what return codes digest_check_auth() should
  return to the distributor and the implications of changing them.

'Add SHA-256 and SHA-512-256 as authentication digest algorithms'
'res_pjsip: Add new AOR option "qualify_2xx_only"'
...have modified alembic scripts for the following database tables: ps_aors,
ps_contacts, ps_auths, ps_globals. If you don't use the scripts to update
your database, reads from those tables will succeeed but inserts into the
ps_contacts table by res_pjsip_registrar will fail.

b0764ad492 res_pjsip: Fix startup/reload memory leak in config_auth.
An issue in config_auth.c:ast_sip_auth_digest_algorithms_vector_init() was
causing double allocations for the two supported_algorithms vectors to the
tune of 915 bytes.  The leak only happens on startup and when a reload is done
and doesn't get bigger with the number of auth objects defined.

* Pre-initialized the two vectors in config_auth:auth_alloc().
* Removed the allocations in ast_sip_auth_digest_algorithms_vector_init().
* Added a note to the doc for ast_sip_auth_digest_algorithms_vector_init()
  noting that the vector passed in should be initialized and empty.
* Simplified the create_artificial_auth() function in pjsip_distributor.
* Set the vector initialization count to 0 in config_global:global_apply().

* Sort and discard any .0.0 and following tags where the commit
  appeared in an earlier branch.

* The result is a single tag for each branch where the application or function
  was defined.

The events defined in res/res_pjsip/pjsip_manager.xml were done by hand
because the XML was extracted from the C source file relatively recently.

Two bugs were fixed along the way...

* The get_documentation awk script was exiting after it processed the first
  DOCUMENTATION block it found in a file.  We have at least 1 source file
  with multiple DOCUMENTATION blocks so only the first one in them was being
  processed.  The awk script was changed to continue searching rather
  than exiting after the first block.

* Fixing the awk script revealed an issue in logger.c where the third
  DOCUMENTATION block contained a XML fragment that consisted only of
  a managerEventInstance element that wasn't wrapped in a managerEvent
  element.  Since logger_doc.xml already existed, the remaining fragments
  in logger.c were moved to it and properly organized.

1ccf0ae7e8 docs: Add version information to configObject and configOption XML elements
Most of the configObjects and configOptions that are implemented with
ACO or Sorcery now have `<since>/<version>` elements added.  There are
probably some that the script I used didn't catch.  The version tags were
determined by the following...
 * Do a git blame on the API call that created the object or option.
 * From the commit hash, grab the summary line.
 * Do a `git log --grep <summary>` to find the cherry-pick commits in all
   branches that match.
 * Do a `git patch-id` to ensure the commits are all related and didn't get
   a false match on the summary.
 * Do a `git tag --contains <commit>` to find the tags that contain each
   commit.
 * Weed out all tags not <major>.<minor>.0.
 * Sort and discard any <major>.0.0 and following tags where the commit
   appeared in an earlier branch.
 * The result is a single tag for each branch where the API was last touched.

configObjects and configOptions elements implemented with the base
ast_config APIs were just not possible to find due to the non-deterministic
way they are accessed.

Also note that if the API call was on modified after it was added, the
version will be the one it was last modified in.

Final note:  The configObject and configOption elements were introduced in
12.0.0 so options created before then may not have any XML documentation.

e7801702c6 res_pjsip_authenticator_digest: Fix issue with missing auth and DONT_OPTIMIZE
The return code fom digest_check_auth wasn't explicitly being initialized.
The return code also wasn't explicitly set to CHALLENGE when challenges
were sent.  When optimization was turned off (DONT_OPTIMIZE), the compiler
was setting it to "0"(CHALLENGE) which worked fine.  However, with
optimization turned on, it was setting it to "1" (SUCCESS) so if there was
no incoming Authorization header, the function was returning SUCCESS to the
distributor allowing the request to incorrectly succeed.

The return code is now initialized correctly and is now explicitly set
to CHALLENGE when we send challenges.

2253fa052d chan_iax2: Avoid unnecessarily backlogging non-voice frames.
Currently, when receiving an unauthenticated call, we keep track
of the negotiated format in the chosenformat, which allows us
to later create the channel using the right format. However,
this was not done for authenticated calls. This meant that in
certain circumstances, if we had not yet received a voice frame
from the peer, only certain other types of frames (e.g. text),
there were no variables containing the appropriate frame.
This led to problems in the jitterbuffer callback where we
unnecessarily bailed out of retrieving a frame from the jitterbuffer.
This was logic intentionally added in commit 73103bdcd5
in response to an earlier regression, and while this prevents
crashes, it also backlogs legitimate frames unnecessarily.

The abort logic was initially added because at this point in the
code, we did not have the negotiated format available to us.
However, it should always be available to us as a last resort
in chosenformat, so we now pull it from there if needed. This
allows us to process frames the jitterbuffer even if voicefmt
and peerfmt aren't set and still avoid the crash. The failsafe
logic is retained, but now it shouldn't be triggered anymore.

  ```
  config show help <module> <object>
  config show help <module> <object> <option>
  core show application <app>
  core show function <func>
  manager show command <command>
  manager show event <event>
  agi show commands topic <topic>
  ```

* Refactored the commands above to output their sections in the same order:
  Synopsis, Since, Description, Syntax, Arguments, SeeAlso

* Refactored the commands above so they all use the same pattern for writing
  the output to the CLI.

* Fixed several memory leaks caused by failure to free temporary output
  buffers.

* Added a "since" array to the mustache template for the top-level resources
  (Channel, Endpoint, etc.) and to the paths/methods underneath them. These
  will be added to the generated markdown if present.
  Example:
  ```
    "resourcePath": "/api-docs/channels.{format}",

        "res_stasis_answer",
        "res_stasis_playback",

fd52a4411d Add SHA-256 and SHA-512-256 as authentication digest algorithms
* Refactored pjproject code to support the new algorithms and
added a patch file to third-party/pjproject/patches

* Added new parameters to the pjsip auth object:
  * password_digest = <algorithm>:<digest>
  * supported_algorithms_uac = List of algorithms to support
    when acting as a UAC.
  * supported_algorithms_uas = List of algorithms to support
    when acting as a UAS.
  See the auth object in pjsip.conf.sample for detailed info.

* Updated both res_pjsip_authenticator_digest.c (for UAS) and
res_pjsip_outbound_authentocator_digest.c (UAC) to suport the
new algorithms.

The new algorithms are only available with the bundled version
of pjproject, or an external version > 2.14.1.  OpenSSL version
1.1.1 or greater is required to support SHA-512-256.

Resolves: #948

UserNote: The SHA-256 and SHA-512-256 algorithms are now available
for authentication as both a UAS and a UAC.

6e114c7869 config.c: retain leading whitespace before comments
Configurations loaded with the ast_config_load2() API and later written
out with ast_config_text_file_save2() will have any leading whitespace
stripped away.  The APIs should make reasonable efforts to maintain the
content and formatting of the configuration files.

This change retains any leading whitespace from comment lines that start
with a ";".

32bf6bbf13 config.c: Fix off-nominal reference leak.
This was identified and fixed by @Allan-N in #918 but it is an
important fix in its own right.

The fix here is slightly different than Allan's in that we just move
the initialization of the problematic AO2 container to where it is
first used.

Fixes #1046

3f59c40b5e Add C++ Standard detection to configure and fix a new C++20 compile issue
* The autoconf-archive package contains macros useful for detecting C++
  standard and testing other C++ capabilities but that package was never
  included in the install_prereq script so many existing build environments
  won't have it.  Even if it is installed, older versions won't newer C++
  standards and will actually cause an error if you try to test for that
  version. To make it available for those environments, the
  ax_cxx_compile_stdcxx.m4 macro has copied from the latest release of
  autoconf-archive into the autoconf directory.

* A convenience wrapper(ast_cxx_check_std) around ax_cxx_compile_stdcxx was
  also added so checking the standard version and setting the
  asterisk-specific PBX_ variables becomes a one-liner:
  `AST_CXX_CHECK_STD([std], [force_latest_std])`.
  Calling that with a version of `17` for instance, will set PBX_CXX17
  to 0 or 1 depending on whether the current c++ compiler supports stdc++17.
  HAVE_CXX17 will also be 'defined" or not depending on the result.

* C++ compilers hardly ever default to the latest standard they support.  g++
  version 14 for instance supports up to C++23 but only uses C++17 by default.
  If you want to use C++23, you have to add `-std=gnu++=23` to the g++
  command line.  If you set the second argument of AST_CXX_CHECK_STD to "yes",
  the macro will automatically keep the highest `-std=gnu++` value that
  worked and pass that to the Makefiles.

* The autoconf-archive package was added to install_prereq for future use.

* Updated configure.ac to use AST_CXX_CHECK_STD() to check for C++
  versions 11, 14, 17, 20 and 23.

* Updated configure.ac to accept the `--enable-latest-cxx-std` option which
  will set the second option to AST_CXX_CHECK_STD() to "yes".  The default
  is "no".

* ast_copy_string() in strings.h declares the 'sz' variable as volatile and
  does an `sz--` on it later.  C++20 no longer allows the `++` and `--`
  increment and decrement operators to be used on variables declared as
  volatile however so that was changed to `sz -= 1`.
