George Joseph 09052bfa51 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.

Naveen Albert fa3922a4d2 manager.c: Fix regression due to using wrong free function.
Commit 424be34563 introduced
a regression by calling ast_free on memory allocated by
realpath. This causes Asterisk to abort when executing this
function. Since the memory is allocated by glibc, it should
be freed using ast_std_free.

George Joseph 8c3ececb12 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.

Gitea a1ca026825 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.

Ben Ford 424be34563 manager.c: Prevent path traversal with GetConfig.
When using AMI GetConfig, it was possible to access files outside of the
Asterisk configuration directory by using filenames with ".." and "./"
even while live_dangerously was not enabled. This change resolves the
full path and ensures we are still in the configuration directory before
attempting to access the file.

Sean Bright 1920639eab pbx_config.c: Don't crash when unloading module.
`pbx_config` subscribes to manager events to capture the `FullyBooted`
event but fails to unsubscribe if the module is loaded after that
event fires. If the module is unloaded, a crash occurs the next time a
manager event is raised.

We now unsubscribe when the module is unloaded if we haven't already
unsubscribed.

George Joseph 1a0acabb8a ast_coredumper: Increase reliability
Instead of searching for the asterisk binary and the modules in the
filesystem, we now get their locations, along with libdir, from
the coredump itself...

For the binary, we can use `gdb -c <coredump> ... "info proc exe"`.
gdb can print this even without having the executable and symbols.

Once we have the binary, we can get the location of the modules with
`gdb ... "print ast_config_AST_MODULE_DIR`

If there was no result then either it's not an asterisk coredump
or there were no symbols loaded.  Either way, it's not usable.

For libdir, we now run "strings" on the note0 section of the
coredump (which has the shared library -> memory address xref) and
search for "libasteriskssl|libasteriskpj", then take the dirname.

Since we're now getting everything from the coredump, it has to be
correct as long as we're not crossing namespace boundaries like
running asterisk in a docker container but trying to run
ast_coredumper from the host using a shared file system (which you
shouldn't be doing).

There is still a case for using --asterisk-bin and/or --libdir: If
you've updated asterisk since the coredump was taken, the binary,
libraries and modules won't match the coredump which will render it
useless.  If you can restore or rebuild the original files that
match the coredump and place them in a temporary directory, you can
use --asterisk-bin, --libdir, and a new --moddir option to point to
them and they'll be correctly captured in a tarball created
with --tarball-coredumps.  If you also use --tarball-config, you can
use a new --etcdir option to point to what normally would be the
/etc/asterisk directory.

Also addressed many "shellcheck" findings.

Sean Bright 008731b0a4 logger.c: Move LOG_GROUP documentation to dedicated XML file.
The `get_documentation` awk script will only extract the first
DOCUMENTATION block that it finds in a given file. This is by design
(9bc2127) to prevent AMI event documentation from being pulled in to
the core.xml documentation file.

Because of this, the `LOG_GROUP` documentation added in 89709e2 was
not being properly extracted and was missing fom the resulting XML
documentation file. This commit moves the `LOG_GROUP` documentation to
a separate `logger.xml` file.

Matthew Fredrickson 45da3ff9fa 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.

Sean Bright 3026ac08ab app_voicemail.c: Completely resequence mailbox folders.
Resequencing is a process that occurs when we open a voicemail folder
and discover that there are gaps between messages (e.g. `msg0000.txt`
is missing but `msg0001.txt` exists). Resequencing involves shifting
the existing messages down so we end up with a sequential list of
messages.

Currently, this process stops after reaching a threshold based on the
message limit (`maxmsg`) configured on the current folder. However, if
`maxmsg` is lowered when a voicemail folder contains more than
`maxmsg + 10` messages, resequencing will not run completely leaving
the mailbox in an inconsistent state.

We now resequence up to the maximum number of messages permitted by
`app_voicemail` (currently hard-coded at 9999 messages).

Naveen Albert 1ce9e1fa8f sig_analog: Fix channel leak when mwimonitor is enabled.
When mwimonitor=yes is enabled for an FXO port,
the do_monitor thread will launch mwi_thread if it thinks
there could be MWI on an FXO channel, due to the noise
threshold being satisfied. This, in turns, calls
analog_ss_thread_start in sig_analog. However, unlike
all other instances where __analog_ss_thread is called
in sig_analog, this call path does not properly set
pvt->ss_astchan to the Asterisk channel, which means
that the Asterisk channel is NULL when __analog_ss_thread
starts executing. As a result, the thread exits and the
channel is never properly cleaned up by calling ast_hangup.

This caused issues with do_monitor on incoming calls,
as it would think the channel was still owned even while
receiving events, leading to an infinite barrage of
warning messages; additionally, the channel would persist
improperly.

To fix this, the assignment is added to the call path
where it is missing (which is only used for mwi_thread).
A warning message is also added since previously there
was no indication that __analog_ss_thread was exiting
abnormally. This resolves both the channel leak and the
condition that led to the warning messages.

Sean Bright ca931c9436 app.c: Allow ampersands in playback lists to be escaped.
Any function or application that accepts a `&`-separated list of

single quoting the filename. Additionally, this is also possible when
using the `CONFBRIDGE` dialplan function, or configuring various
features in `confbridge.conf` and `queues.conf`.

George Joseph f309ffad3d 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
