[Bug 25923] isTypeSupported should be asynchronous

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

--- Comment #21 from Mark Watson <watsonm@netflix.com> ---
I don't think we should assume that any user-permission for the CDM is obtained
on creation of the MediaKeys object. UAs should have flexibility to handle
user-permission on whatever basis they deem that appropriate (for example when
the browser is installed / upgraded).

I think we should ensure, though, that if a process is going to take
considerable time (e.g. download) then it should be clear whether it is the UA
or the site that is responsible for progress indications (and probably it
should be the UA).
