There are two issues in our current setup
1) Input events which are occurring in the same tab are going to be lost
because sync XHR. We have event handling suppression for synx XHR, so input
events are going to be discarded.
2) Input events that are happening in another tab (same process as the
synx XHR tab) are not going to be delayed. This is not correct since
sync XHR should block the Javascript execution.
This patches fixes the above cases for when both TaskController and e10s are
enabled by suspending the InputTaskManager during sync XHR, which
delays the input event handling and keeps the events around.

In many cases with wpt, most of the tests in the file pass, but it is rather time consuming to annotate
.ini files case by case.

ContentTask tasks have a different lifetime than SpecialPowers tasks, with the
former being tied to the lifetime of a message manager and the latter tied to
the lifetime of a window global. That means that existing ContentTask callers
which expect to be able to register load listeners before the creation of a
window global, or which expect to persist after a page has navigated, won't
work as SpecialPowers tasks.
Since those sorts of tasks are not really resilient in the face of Fission,
they should really be written to work differently, but this patch mostly just
reverts them to using ContentTask for the time being.

This is generally pretty straightforward, and rewrites nearly all calls. It
skips the ones that it can detect using frame script globals like
`sendAsyncMessage`, though.

The way this test works is, it loads a page, then it navigates to
another page and exits. The mochitest browser-chrome leak detector
will report a leak if the first page isn't freed by the end of the
test.
To make this Fission-compatible, I first changed the page we navigate
to to be same-origin. This means that we won't tear down the original
process immediately when we navigate, which will break the various
test harness stuff.
Secondly, I enable the dom.ipc.keepProcessesAlive.webIsolated
preference, which means that the content process won't be torn down
immediately. If this pref is not set, then the usual process reuse
ends up destroying the window before the test ends, whether or not it
leaks.
I verified that this test fails when the patch from bug 1336811 is
backed out, both with and without Fission.

Most of these tests have been disabled for a long time; they run well
in the current test environment.
With the additional tests running, task times increase; I have added one
more test chunk for android mochitest-plain.
These tests were identified from a random sampling of mochitest manifests;
I intend to enable more mochitests in future patches.
