[apis] Media API TF report

tracker: ACTION-178

Bin, all,
I had an action point to draft the TF report. See attached. As agreed
during last call, I'm only pointing to the wiki, so the document is quite
slim. Let me know if you think it should contain more content.

The "gaps" section is of course still empty as there was an action on you
(Bin) to provide a straw-man for it. Once you have it I can incorporate it.

I have one question about the cross-reference table that we have produced.
As this is a google doc, I was wondering if it would be more appropriate to
save it in some format and upload it to the wiki (or someone else) and link
it that way. Or do people think is ok to keep a link to a google doc?
