4715c1b11c Revert "core & res_pjsip: Improve topology change handling."
This reverts commit 315eb551db.

Over the past year, we've had several reports of "topology storms"
occurring where 2 external facing channels connected by one or more
local channels and bridges will get themselves in a state where
they continually send each other topology change requests.  This
usually manifests itself in no-audio calls and a flood of
"Exceptionally long queue length" messages.  It appears that this
commit is the cause so we're reverting it for now until we can
determine a more appropriate solution.

b074c97f00 res_rtp_asterisk: Fix regression issues with DTLS client check
* Since ICE candidates are used for the check and pjproject is
  required to use ICE, res_rtp_asterisk was failing to compile
  when pjproject wasn't available.  The check is now wrapped
  with an #ifdef HAVE_PJPROJECT.

* The rtp->ice_active_remote_candidates container was being
  used to check the address on incoming packets but that
  container doesn't contain peer reflexive candidates discovered
  during negotiation. This was causing the check to fail
  where it shouldn't.  We now check against pjproject's
  real_ice->rcand array which will contain those candidates.

* Also fixed a bug in ast_sockaddr_from_pj_sockaddr() where
  we weren't zeroing out sin->sin_zero before returning.  This
  was causing ast_sockaddr_cmp() to always return false when
  one of the inputs was converted from a pj_sockaddr, even
  if both inputs had the same address and port.

5e168ebcd8 res_pjsip_header_funcs: Duplicate new header value, don't copy.
When updating an existing header the 'update' code incorrectly
just copied the new value into the existing buffer. If the
new value exceeded the available buffer size memory outside
of the buffer would be written into, potentially causing
a crash.

This change makes it so that the 'update' now duplicates
the new header value instead of copying it into the existing
buffer.

bfac3945f6 res_odbc.c: Allow concurrent access to request odbc connections
There are valid scenarios where res_odbc's connection pool might have some dead
or stuck connections while others are healthy (imagine network
elements/firewalls/routers silently timing out connections to a single DB and a
single IP address, or a heterogeneous connection pool connected to potentially
multiple IPs/instances of a replicated DB using a DNS front end for load
balancing and one replica fails).

In order to time out those unhealthy connections without blocking access to
other parts of Asterisk that may attempt access to the connection pool, it would
be beneficial to not lock/block access around the entire pool in
_ast_odbc_request_obj2 while doing potentially blocking operations on connection
pool objects such as the connection_dead() test, odbc_obj_connect(), or by
dereferencing a struct odbc_obj for the last time and triggering a
odbc_obj_disconnect().

This would facilitate much quicker and concurrent timeout of dead connections
via the connection_dead() test, which could block potentially for a long period
of time depending on odbc.ini or other odbc connector specific timeout settings.

This also would make rapid failover (in the clustered DB scenario) much quicker.

This patch changes the locking in _ast_odbc_request_obj2() to not lock around
odbc_obj_connect(), _disconnect(), and connection_dead(), while continuing to
lock around truly shared, non-immutable state like the connection_cnt member and
the connections list on struct odbc_class.

cd77953172 chan_pjsip: Add PJSIPHangup dialplan app and manager action
See UserNote below.

Exposed the existing Hangup AMI action in manager.c so we can use
all of it's channel search and AMI protocol handling without
duplicating that code in dialplan_functions.c.

Added a lookup function to res_pjsip.c that takes in the
string represenation of the pjsip_status_code enum and returns
the actual status code.  I.E.  ast_sip_str2rc("DECLINE") returns
603.  This allows the caller to specify PJSIPHangup(decline) in
the dialplan, just like Hangup(call_rejected).

Also extracted the XML documentation to its own file since it was
almost as large as the code itself.

UserNote: A new dialplan app PJSIPHangup and AMI action allows you
to hang up an unanswered incoming PJSIP call with a specific SIP
response code in the 400 -> 699 range.

9efc4bdfbc res_pjsip_exten_state,res_pjsip_mwi: Allow unload on shutdown
Commit f66f77f last year prevents the res_pjsip_exten_state and
res_pjsip_mwi modules from unloading due to possible pjproject
asserts if the modules are reloaded. A side effect of the
implementation is that the taskprocessors these modules use aren't
being released. When asterisk is doing a graceful shutdown, it
waits AST_TASKPROCESSOR_SHUTDOWN_MAX_WAIT seconds for all
taskprocessors to stop but since those 2 modules don't release
theirs, the shutdown hangs for that amount of time.

This change allows the modules to be unloaded and their resources to
be released when ast_shutdown_final is true.

f89e56c178 res_pjsip: Expanding PJSIP endpoint ID and relevant resource length to 255 characters
This commit introduces an extension to the endpoint and relevant
resource sizes for PJSIP, transitioning from its current 40-character
constraint to a more versatile 255-character capacity. This enhancement
significantly overcomes limitations related to domain qualification and
practical usage, ultimately delivering improved functionality. In
addition, it includes adjustments to accommodate the expanded realm size
within the ARI, specifically enhancing the maximum realm length.

Resolves: #345

UserNote: With this update, the PJSIP realm lengths have been extended
to support up to 255 characters.

UpgradeNote: As part of this update, the maximum allowable length
for PJSIP endpoints and relevant resources has been increased from
40 to 255 characters. To take advantage of this enhancement, it is
recommended to run the necessary procedures (e.g., Alembic) to
update your schemas.

79220e3f0c res_stasis: signal when new command is queued
res_statsis's app loop sleeps for up to .2s waiting on input
to a channel before re-checking the command queue. This can
cause delays between channel setup and bridge.

This change is to send a SIGURG on the sleeping thread when
a new command is enqueued. This exits the sleeping thread out
of the ast_waitfor() call triggering the new command being
processed on the channel immediately.

Resolves: #362

UserNote: Call setup times should be significantly improved
when using ARI.

edc674a6ca res_pjsip_transport_websocket: Prevent transport from being destroyed before message finishes.
From the gdb information, ast_websocket_read reads a message successfully,
then transport_read is called in the serializer. During execution of pjsip_transport_down,
ws_session->stream->fd is closed; ast_websocket_read encounters an error and exits the while loop.
After executing transport_shutdown, the transport's reference count becomes 0, causing a crash when sending SIP messages.
This was due to pjsip_transport_dec_ref executing earlier than pjsip_rx_data_clone, leading to this issue.
In websocket_cb executeing pjsip_transport_add_ref, this we now ensure the transport is not destroyed while in the loop.

8be503b663 res_pjsip_header_funcs: Make prefix argument optional.
The documentation for PJSIP_HEADERS claims that
prefix is optional, but in the code it is actually not.
However, there is no inherent reason for this, as users
may want to retrieve all header names, not just those
beginning with a certain prefix.

This makes the prefix optional for this function,
simply fetching all header names if not specified.
As a result, the documentation is now correct.

Resolves: #230

UserNote: The prefix argument to PJSIP_HEADERS is now
optional. If not specified, all header names will be
returned.

25a766f49d res_rtp_asterisk: Move ast_rtp_rtcp_report_alloc using rtp->themssrc_valid into the scope of the rtp_instance lock.
From the gdb information, it was found that when calling __ast_free, the size of the
allocated space pointed to by the pointer matches the size created when rtp->themssrc_valid
is equal to 0. However, in reality, when reading the value of rtp->themssrc_valid in gdb,
it is found to be 1.

Within ast_rtcp_write(), the call to ast_rtp_rtcp_report_alloc() uses rtp->themssrc_valid,
which is outside the protection of the rtp_instance lock. However,
ast_rtcp_generate_report(), which is called by ast_rtcp_generate_compound_prefix(), uses
rtp->themssrc_valid within the protection of the rtp_instance lock.

This can lead to the possibility that the value of rtp->themssrc_valid used in the call to
ast_rtp_rtcp_report_alloc() may be different from the value of rtp->themssrc_valid used
within ast_rtcp_generate_report().
