[Bug 25923] isTypeSupported should be asynchronous

https://www.w3.org/Bugs/Public/show_bug.cgi?id=25923

--- Comment #13 from David Dorwin <ddorwin@google.com> ---
I agree with comment #12.

On Topic #2:
We should work through and standardize the expected flow, including any
possible prompts. In particular, how should isTypeSupported() respond in the no
permissions case and should prompts always occur in MediaKeys.create()?

On Topic #1: 
If we do not need to worry about user interaction, we can simply look at the
appropriate design for this simple query. While asynchronous APIs are generally
preferred and isTypeSupported() may need to query the platform or make other
IPCs (the first time it is called), it is probably better for authors,
implementors, and possibly even the user experience to make a few synchronous
calls instead of potentially 10s of asynchronous calls.
