Attachment: Bug 1281932 - Fix intermittent u2f tests

This is reworking the U2F tests to do two things:

1) Don't run all the tests in one big frame; that makes it hard to tell
   what test is actually dying in Treeherder.
2) Fix the obvious possible test races with the async functions which could be
   causing the intermittent

Ok - lgtm.

My assumption would be that support-files should be sorted, but it's probably not a big deal

nit: this comment appears to be a bit outdated at this point (same in all of the changed test_* files)

Seems like completed could be defined in u2futil.js.

It might be good to note a test failure if ever countCompletions > expectedCompletions.

else indicate a test failure?

console.log might be more helpful ultimately (or maybe in addition?)

Yeah, I was lazy. :) Added `local_addTest` and `local_completeTest` to `u2futil.js` in patch 2.

> nit: s/var/let/ here

Thanks. I fixed this throughout `u2futil.js`.

> else indicate a test failure?

Good idea.

> console.log might be more helpful ultimately (or maybe in addition?)

Tossed it in there.

Second try run looks quite good. Marking checkin-needed.
