This moves netsock.c / netsock.h to the chan_iax2 module.  netsock.h has
been marked deprecated since 13.0.0, chan_iax2 is the only remaining
user.

The completion generator is missing a return so typing "core set debug
all off <tab>" causes the command to actually execute.

The Local channel has never supported app_transfer

Attempting to dial PJSIP/endpoint when the endpoint doesn't exist and
disable_multi_domain=no results in a misleading empty endpoint name
message.  The message should say the endpoint was not found.

* Added missing endpoint not found message.

* Added more information to the empty endpoint name msgs if available.

* Eliminated RAII_VAR in request().

Remove nearly all use of regex from ACO users.  Still remaining:
* app_confbridge has a legitamate use of option name regex.
* ast_sorcery_object_fields_register is implemented with regex, all
  callers use simple prefix based regex.  I haven't decided the best
  way to fix this in both 13/15 and master.

ACO uses regex in many situations where it is completely unneeded.  In
some cases this doubles the total processing performed by
aco_process_config.

* Create ACO_IGNORE category type for use in place of skip_category
  regex source string.
* Create additional aco_category_op values to allow specifying category
  filter using either a single plain string or a NULL terminated array
  of plain strings.
* Create ACO_PREFIX to allow matching option names to case insensitive
  prefixes.

When adding shutdown refs for OPTIONAL_API components I accidentally
added it to the unload_module function in res_smdi.  Move it to
load_module.

res_hep_pjsip.so and res_hep_rtcp.so will still load and do a lot of

* Split off load_dlopen to perform actual dlopen, check results and log
  warnings when needed.
* Always use RTLD_NOW.
* Use flags which minimize number of calls to dlopen required.  First
  attempt always uses RTLD_GLOBAL when global_symbols_only is enabled,
  RTLD_LOCAL when it is not.

This patch significantly reduces the number of dlopen's performed.  With
299 modules my system ran dlopen 857 times before this patch, 655 times
after this patch.

This protects the module loader itself against crashing if dlopen is
called on a module from outside loader.c.

* Expand scope of lock inside ast_module_register to include reading of
  resource_being_loaded.
* NULL check resource_being_loaded.
* Set resource_being_loaded NULL as soon as dlopen returns.  This fixes
  some error paths where it was not NULL'ed.
* Create module_destroy function to deduplicate code from
  ast_module_unregister and modules_shutdown.
* Resolve leak that occured if a module did not successfully register.
* Simplify checking for successful registration.

We should not do flood detection on video RTP streams.  Video RTP streams
are very bursty by nature.  They send out a burst of packets to update the
video frame then wait for the next video frame update.  Really only audio
streams can be checked for flooding.  The others are either bursty or
don't have a set rate.

* Added code to selectively disable packet flood detection for video RTP
streams.
