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.

This takes account of the fact that zones may be added to the waiting set
during an incremental GC, after the set has been cleared in
CycleCollectedJSRuntime::PrepareWaitingZonesForGC. I considered disallowing
zones to be added to the set during a GC but decided it would be better not to
lose track of poked zones in the usual case where they don't end up getting
destoryed by the current GC.

This adds assertions that zone pointers passed in refer to zones we know about
and adds and API that's called when zones are destroyed. It also adds some
standard assertions for other related APIs.

We don't properly implement them in JS, so only allow them for C++.
This patch also makes the only remaining non-builtinclass interface
with a nostdcall method, nsIBinaryOutputStream, builtinclass.
This also changes the isScriptable() method to be consistent,
though I think the change doesn't matter because the only
place that calls it also checks if the interface is builtinclass.

This causes no behavior changes in the current code because existing runnables
passed to NS_DispatchToThreadQueue() are either run on the main thread where
OnDiscard() is not called or they have only a no-op OnDiscard().

Currently, printf_stderr doesn't show up when running with ./mach run.
This is because we run with -attach-console and that redirects stderr
to a different file descriptor using freopen in UseParentConsole.
The change from just using stderr directly happened in bug 340443 and was done
to avoid some linking issues. That problem doesn't seem to apply anymore so we
should be able to go back to the straightforward implemention that works even
if stderr has been redirected. The mozglue implementation was cargo culted from
xpcom, and there wasn't a reason other than that for the fdopen(dup()) there.

Callers can pass an exit code to nsIAppStartup::Quit and it will be returned from the process when
it exits.
Note that I have using uint16_t as the exit code because on Windows the exit code can be a uint and
elsewhere it is an int. A uint16_t will safely convert to either of those and no-one will ever need
more than 64k exit codes!

Classes that inherit from DiscardableRunnable are only promising that it is OK
for Run() to be skipped, rather than promising that Cancel() is effective.

CheckAndCreateBloatView() is infallible, so there's no need to check if it
worked.
I also renamed the function to EnsureBloatView() because that better matches the
common practice, and what the function is actually doing.
Finally, I added a small grammar fix.

This is a workaround for bug 1670737 to avoid spamming a saturated
thread pool with too many events.
Also converts some unused code to a gtest.
