Bobby Holley 91448a9dac Bug 868130 - Remove the lion's share of JSAutoRequests in gecko. r=gabor
There are still a handful that either are used with other runtimes, or that
happen very early/late in cx the lifetime of various things where it doesn't
necessarily make sense to have a cx on the stack. This should definitely ensure
that we're not doing double-duty with the nsCxPusher change, though.
