<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Just a thought, what if this used the ACO model of creating an ao2_container *attr_offset to lookup the field offset's? Not sure if that would be more or less efficient, but would look cleaner / easier to maintain.
This idea applies to all format_attribute_set callbacks.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">These modules haven't changed since they were implemented really, I think going forward any future modules should evaluate whether that is a good idea or not.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This change does a few things:
1. Fixes an issue where direct format interfaces were treated as AO2 objects when they were not.
2. Added an ast_format_clone API call which clones and deep copies a format, returning one which can be safely modified.
3. Changed the format interface API so anything which manipulates the format returns a new format.
4. Added get/set functions for format attribute data.
5. Added an API call to replace the format in an RTP engine codecs structure.
6. Updated the res_format_attr_* modules to work with the new media formats work.
7. Added support for loading an interface module after a format has been created.</pre>
