Bugs: ASTERISK-24479
    https://issues.asterisk.org/jira/browse/ASTERISK-24479


Repository: Asterisk


Description
-------

This change includes an ABI change with compatibility stubs for 11, 12 and 13.  
The compatibility stubs will not be included in trunk.  The point of this 
change is to have each module create an AO2 object on load, and hopefully 
destroy it on unload.  This allows module reference count errors to be debugged 
through REF_DEBUG.

When REF_DEBUG is enabled:
* adds an empty ao2 object to 'struct ast_module'
* Allocate ao2 when the module is loaded
* Perform an ao2_ref in each place where mod->usecount is manipulated.
* ao2_cleanup on module unload.


The passthrough of file, line and func is needed for the REF_DEBUG to be of any 
use, so without the ABI changes this is not useful.

The change to bridge_builtin_features.c ensures that the module cannot be 
manually unloaded, but is able to be unloaded during ast_module_shutdown.  Note 
ast_module_shutdown only happens during clean shutdown and does not actually 
run dlclose so this is safe.

Testing
-------

Using tests/manager/originate with REF_DEBUG enabled.  When the change to 
bridge_builtin_features.c is omitted the test fails due to that one reference 
leak.


Thanks,

Corey Farrell
