Also as discussed on IRC I'd like to see an assert so we can identify NULL format issues.</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 patch does two things:
* It updates a few of the unit tests for some of the API changes. In particular, it focuses on adding some tests for formats with attributes and their expected behaviour. A few other non-format related unit tests were updated as well to handle off nominals detected during testing.
* It adds an 'ast_format_none' format. This format is a dummy format that can be used instead of a NULL pointer to prevent having to put NULL dereference checks into every place in the codebase. Channels are no assigned this format immediately upon creation, and their default capabilities are set to have it. As this format's codec has no translation (nor a representation in the RTP engine), it _shouldn't_ cause harm.
* A few NULL checks were put in anyway into key areas in a few modules. These were ones that were hit hard by the unit tests and prone to crashing if presented a NULL format.</pre>

There is a FRACK on shutdown, but it doesn't appear to be caused by this patch (things didn't run long enough without this patch before)</pre>
