d73e139013 bridge_channel: don't set cause code on channel during bridge delete if already set
Due to a potential race condition via ARI when hanging up a channel hangup with cause
while also deleting a bridge containing that channel, the bridge delete can over-write
the hangup cause code resulting in Normal Call Clearing instead of the set value.

With this change, bridge deletion will only set the hangup code if it hasn't been
previously set.

5b8dcba9c4 .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.

  * Changed to simply call reusable workflows in asterisk-ci-actions.
  * Changed to use better concurrency groups.

787ffd5f47 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.

da9b7f5f89 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.

6f17f61394 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.

d402b59ec2 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.

8afca5306a 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.

3488093159 alembic: Database updates required.

'Add SHA-256 and SHA-512-256 as authentication digest algorithms'
'res_pjsip: Add new AOR option "qualify_2xx_only"'

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

7d615466ee 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.

c83a6fb64a 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().

* 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.

ded24e3375 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.

0599f3a869 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.

7c5efec2fc 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}",
    "requiresModules": [
        "res_stasis_answer",
        "res_stasis_playback",

10664757d2 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.

b2e81346bb 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 ";".
