Reason for reland:
The original CL actually didn't break browser_tests; it was
just a coincidence that it started failing.

This needs to happen because in the future, m-lines will be offered
based on the set of RtpSenders/RtpReceivers, rather than the set of
tracks that MediaStreamSignaling knows about.
Besides that, MediaStreamSignaling was a "glue class" without
a clearly defined role, so it going away is good for other
reasons as well.

This will prevent it from blocking network input when it falls behind,
which is happening when running with ThreadSanitizer.
