* Make load_module() cleanup if it failed to setup the module.

* Make unload_module() always return 0.  It is silly to fail unloading if
the hook function we try to unregister was not even registered.

If codec_speex fails to register a translator it would cause Asterisk to
exit instead of continue as a DECLINED module.

* Make unload_module() always return 0.  It is silly to fail unloading if
any translators we try to unregister were not even registered.

Fix redirection to /dev/null of cleanup commands.  The '2' was being
interpreted as part of the command instead of part of the redirect.

I think this module is so screwed up that it doesn't work anymore.  Even
with these attempts to fix things it still won't gracefully shut down.
The module refs will not go to zero to allow unloading the module.

* Fix module ref counting dealing with the SMDI interface object.  There
were several off-nominal paths that unbalanced the module ref count.  Also
the destructor freed the ao2 object itself which is bad.  Made the
smdi_read thread not hold its own ref to the SMDI interface object so when
all refs go away the destructor will stop the listener thread.

* Fixed the smdi_load() return code of 1 concerning the number of
listeners.  The test was inverted.

This module is an optional dependency of a couple of other modules.  If it
declines to load, it then forces other modules that can optionally use
this module to also decline.

* Made use the default configuration if the config file does not exist and
simplified some of the logic.

The test for OBJ_NOLOCK looks wrong but it isn't.  Add comments to
prevent confusion.

Also make the shebang in publishAsteriskDocs.sh the first line.

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.

This module is an optional dependency of many modules.  If it declines to
load it then forces other modules that can optionally use this module to
also decline.

* Made use default configuration if there is a config error or the config
file does not exist.

* ACO options
* Indications
* Module loader ref_debug object
* Media index info and variants
* xmldoc items

These allocation locations were identified using reflocks.py on the
master branch.

When a module reload fails we never set AST_MODULE_RELOAD_ERROR.  This
caused reload failures to incorrectly report 'No module found'.

* 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.

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.
