If we're going to change the meaning of an enum, we should change its name, too,
just to avoid confusion.  Otherwise we'll have to go digging through commit logs
to figure out what "OFFLINE_UNUSABLE" actually means for a given revision number
every time that status shows up on crbug.

Regardless, I don't think we should be making this change in a commit that is
meant to fix a different bug and is headed for M18.
