MediaStream API: Changing the device enumeration to be async
When we stared to implement this in chrome we discovered that sometimes
device enumeration could take some time and therefore the API needed
to be adjusted. This has been discussed on the W3C email list without
objections but not yet reached the editors draft.
The old name getSourceInfos got changed to getSources as well.
