Replace "information in the AV" with "information in the MAD".

And now for a coherent version...  The mad elements provide fields for
addressing information that can be used instead of providing a valid AV handle.
This is especially useful if replying to a MAD, where the received MAD already
has all the information filled in by the MAD layer.  This allows a received mad
to be reused and sent back to the sender without having to do any AV management
in the recipient's code - the MAD service will create an AV for the send, and
destroy it when the send completes.

I have plans to add AV caching in the kernel, as well as adding redirection
support.  Rather than duplicate caching in clients and expose redirection APIs I
would rather just keep that internal to the access layer and have clients just
fill in the addressing information in the MAD element and leave the AV handle
NULL.

Hopefully that makes a little more sense than what I wrote above.
