Status of bikeshed

The conversion of the spec to bikeshed is, essentially, done with much help
from Tab Atkins.  There are currently 6 errors generated by bikeshed.  Of
these, one is a bad link on our part (cors-cross-origin no longer links to
anything useful). The rest are small issues with bikeshed such tat inks to
MediaStream, MediaStreamTrack, and DOMHighResTimestamp don't link to
anything in the IDL sections like other things normally would (like
HTMLMediaElement, and so on.)

AFAICT, everything else works and the spec looks good. (Preview at
https://rawgit.com/tabatkins/web-audio-api/gh-pages/index.html)

So, barring any last minute issues, I'd really like to import the bikeshed
version in the next week or two so that I don't have to merge changes
manually between the two versions anymore.

Until the bikeshed errors are fixed, we won't easily be able to have CI
check for mistakes.  Hopefully that will get remedied soon.
