All,

The previous pull request has become very large. I will break it up into a
sequence of smaller ones. To facilitate this, I need to merge one PR that
establishes the latest framework. The other PRs can then be reviewed in
parallel.

So, the first of this sequence is
https://github.com/w3c/web-platform-tests/pull/3355/files

I URGENTLY need review of this PR. If we are to meet our deadline of August
2, I presume we need the tests running this week and I will have limited
time to work on this tomorrow and Friday. I don't think there is much point
in attempting to meet the August 2 deadline if noone is able to review the
test PRs.

...Mark
