Most were in comments.  A couple were in warning messages.

5ab94d2a3e taskprocessor: Warn on unused result from pushing task.
Add attribute_warn_unused_result to ast_taskprocessor_push,
ast_taskprocessor_push_local and ast_threadpool_push.  This will help
ensure we perform the necessary cleanup upon failure.

79677ead28 refdebug: Create refstats.py script.
This allows us to process AO2 statistics for total objects, memory
usage, memory overhead and lock usage.

* Install refstats.py and reflocks.py into the Asterisk scripts folder.
* Enable support for reflocks.py without DEBUG_THREADS.

Steal a bit from the ao2 magic to flag when an object lock is used.
Remove 'lockobj' from reflocks.py since we can now record 'used' or
'unused' for those objects.

Add comments to explain thread safety of the 'struct __priv_data'
bitfields.

f06de6900e threadpool: Eliminate pointless AO2 usage.
thread_worker_pair, set_size_data and task_pushed_data structures are
allocated with AO2 objects, passed to a taskprocessor, then released.
They never have multiple owners or use locking so AO2 only adds
overhead.

17f4e6ad4d core/frame: generate correct T.140 payload in ast_sendtext_data()
ast_sendtext_data() would create an incorrect T.140 text frame which
length include the null terminator byte. It causes ultimately RTP
packets to be send with this trailing 0. The proposed fix just set the
correct length to the text frame

c8ee1a183f loader: Flag module as declined in all cases where it fails to load.
This has no effect on startup since AST_MODULE_LOAD_FAILURE aborts
startup, but it's possible for this code to be returned on manual load
of a module after startup.

It is an error for a module to not have a load callback but this is not
a fatal system error.  In this case flag the module as declined, return
AST_MODULE_LOAD_FAILURE only if a required module is broken.

Expand doxygen documentation for AST_MODULE_LOAD_*.

286339aa34 http.c: Reload TLS even if http.conf hasn't changed
There is currently no way to indicate to Asterisk that TLS certificates
and/or keys have been updated other than by modifying http.conf or
restarting Asterisk.

There is already code in main/tcptls.c that determines if a reload is
actually necessary based on the hashes of the certicate and dependent
files, so this change merely gives us a way to request a reload without
explicitly modifying http.conf.

b25a261aa5 loader: Fix result of module reload error.
When a module reload fails we never set AST_MODULE_RELOAD_ERROR.  This

e4cf513f81 loader: Improve error handling.
* Display list of unavailable dependencies when they cause another
  module to fail loading.
* When a module declines to load find all modules which depend on it so
  they can be declined and listed together.
* Prevent retry of declined modules during startup.
* When a module fails to dlopen try loading it with RTLD_LAZY so we can
  attempt to display the list of missing dependencies.

These changes are meant to reduce logger spam that is caused when a
module has many dependencies and declines to load.  This also fixes some
error paths which failed to recognize required modules.

Module load/start errors are delayed until the end of loader startup.

24cece660b core/frame: Fix ast_frdup() and ast_frisolate() for empty text frames
If a channel creates an AST_TEXT_FRAME with datalen == 0, the ast_frdup()
and ast_frisolate() functions could create a clone frame with an invalid
data.ptr which would cause a crash.  The proposed fix is to make sure that
for such empty text frames, ast_frdup() and ast_frisolate() return cloned
text frames with a valid data.ptr.

13df745278 astobj2: Record lock usage to refs log when DEBUG_THREADS is enabled.
When DEBUG_THREADS is enabled we can know if the astobj2 mutex / rwlock
was ever used, so it can be recorded in the REF_DEBUG destructor entry.

Create contrib/scripts/reflocks.py to process locking used by
allocator.  This can be used to identify places where
AO2_ALLOC_OPT_LOCK_NOLOCK should be used to reduce memory usage.

astobj2.c to eliminate storage for tracking fields when DEBUG_THREADS is
not defined.

  avoided as it was not thread safe.
* Use "o?" and "O?" to replace NULL with ast_json_null().  The
  "?" is a new feature of ast_json_pack starting with Asterisk 16.

06c0676da0 app_voicemail: Cleanup mailbox topic and cache
app_voicemail wasn't properly cleaning up the stasis cache or the
mwi topic pool when the module was unloaded or when a user was
deleted as a result of a reload.  This resulted in leaks in both
areas.

* app_voicemail now calls ast_delete_mwi_state_full when it frees
  a user structure and ast_delete_mwi_state_full in turn now calls
  the new stasis_topic_pool_delete_topic function to clear the topic
  from the pool.

31fba4e869 rtp_engine: rtcp_report_to_json can overflow the ssrc integer value
When writing an RTCP report to json the code attempts to pack the "ssrc" and
"source_ssrc" unsigned integer values as a signed int value type. This of course
means if the ssrc's unsigned value is greater than that which can fit into a
signed integer value it gets converted to a negative number. Subsequently, the
negative value goes out in the json report.

This patch now packs the value as a json_int_t, which is the widest integer type
available on a given system. This should make it so the value no longer
overflows.

Note, this was caught by two failing tests hep/rtcp-receiver/ and
hep/rtcp-sender.

d277db4a38 stasis: Add function to delete topic from pool
There's been a long standing leak when using topic pools.  The
topics in the pool get cleaned up when the last pool reference is
released but you can't remove a topic specifically.  If you reloaded
app_voicemail for instance, and mailboxes went away, their topics
were left in the pool.

* Added stasis_topic_pool_delete_topic() so modules can clean up
  topics from pools.
* Registered the topic pool containers so it can be examined from
  the CLI when AO2_DEBUG is enabled.  They'll be named
  "<topic_pool_name>-pool".

c99a9b228b stasis: No need to keep a stasis type ref in a stasis msg or cache object.
Stasis message types are global ao2 objects and we make stasis messages
and cache entries hold references to them.  Since there are currently
situations where cache objects are never deleted, the reference count on
the types can exceed 100000 and generate a FRACK assertion message.  The
stasis message cache could conceivably also have that many messages
legitimately on large systems.

The only down side to not holding the message type ref in the stasis
message is it only makes a crash either at shutdown or when manually
unloading a busy module slightly more likely.  However, this is more
exposing a pre-existing stasis shutdown ordering issue than a problem with
not holding a message type ref in stasis messages.

* Made stasis messages and cache entries no longer hold a ref to the
message type.
