Frame locks counted instead of boolean
As part of bug 486918, I want to make it possible to have multiple downscaled images, but doing that makes necessary to lock an imgFrame multiple times. So, instead of trying to only lock when it's not locked, I'm just going to make imgFrame locks counted, like RasterImage already is. First, I need to make our locking correct - always lock when you're going to GetImageData/GetPaletteData. To do that, I'm introducing an RAII class, which I'm sure will make jrmuizel *ecstatic*.

Note that I intentionally made the lock count a signed integer so we can catch logic errors.

Oh, I thought I did. That's actually how I caught those bugs.
Oh, the assertions are in the second patch! Duh.

Target Milestone: --- → mozilla18
Push backed out on suspicion of causing intermittent Android reftest failures like: https://tbpl.mozilla.org/php/getParsedLog.php?id=15640210&tree=Mozilla-Inbound https://tbpl.mozilla.org/php/getParsedLog.php?id=15638930&tree=Mozilla-Inbound https://tbpl.mozilla.org/php/getParsedLog.php?id=15639608&tree=Mozilla-Inbound Retriggers are pending and I believe will confirm one of the bugs in the push to be the cause, but we can't afford to keep the tree closed any longer, so backing this out for now. Retrigger results will be at: https://tbpl.mozilla.org/?tree=Mozilla-Inbound&jobname=%20reftest&rev=92530b29ac24 Backout: https://hg.mozilla.org/integration/mozilla-inbound/rev/28e5dc437921
