Bug 1382341 - removed `this._remove()` from `onWindowReady`; r=pbro This basically revert the changes made in bug 1341756; but it doesn't seems to bring the same issue as before since `pagehide` event is emitted properly when entering in RDM. Added unit test to catch future regression. The removal of duplicated hidden markup in anonymous content will be handled by Bug 1396690. MozReview-Commit-ID: 92qC9CHYL1a

Bug 1370412 - Part 10. Add SurfaceCache gtests for factor of 2 mode. r=tnikkel

Bug 1370412 - Part 9. Add factor of 2 state to the SurfaceCache memory reports. r=tnikkel

Bug 1370412 - Part 8b. Add ImageSurfaceCache::Prune to discard surfaces which are not needed in factor of 2 mode. r=tnikkel

Bug 1370412 - Part 8a. Add "substitutable" flag to ISurfaceProvider state to indicate when the caller won't accept substitutes. r=tnikkel When SurfaceCache::Lookup is called to access surface data, it indicates that the caller will not accept substitutes as in the case of SurfaceCache::LookupBestMatch. As such, we need to be careful not to remove those surfaces from our cache when pruning (in part 8b). This is the marker used to track that, at some point, there was a caller which got this surface that would accept no other (e.g. factor of 2 mode must make an accept for this particular surface).

Bug 1370412 - Part 7. ImageSurfaceCache::Lookup should enter factor of 2 mode on cache misses. r=tnikkel

Bug 1370412 - Part 6. ImageSurfaceCache::LookupBestMatch should enter factor of 2 mode on cache misses. r=tnikkel

Bug 1370412 - Part 5. Add ImageSurfaceCache factor of 2 mode size calculations. r=tnikkel

Bug 1370412 - Part 4. Add ImageSurfaceCache::MaybeSetFactor2Mode and state. r=tnikkel

Bug 1370412 - Part 3. Break out ImageSurfaceCache::CompareArea from LookupBestMatch for reuse. r=tnikkel

Bug 1370412 - Part 2. Give image::LookupResult an optional preferred size to decode at when the surface is not found. r=tnikkel

Bug 1370412 - Part 1. Add preference to control "factor of 2" mode for ImageSurfaceCache. r=tnikkel

Bug 1370412 - Part 0. Add imgIContainer::GetNativeSizesLength to determine a ceiling on the maximum number of expected, unique surfaces. r=tnikkel

Bug 1395828 (part 3) - Remove AssertParserServiceIsCorrect(). r=mrbkap. It's a bit strange for the editor to distrust the parser service in this way. The double-checking seems unnecessary, especially given that it is *buggy*: it incorrectly includes `col`, `colgroup`, and `legend` as block elements, but excludes `pre`. (It must only be called in situations where these incorrectly-classified elements are not passed in, otherwise it would have triggered by now.) So this patch removes it. The patch also removes `li` and `pre` from the IsAnyOfHTMLElements() test in HTMLEditor::NodeIsBlockStatic. Contrary to what the comment in NodeIsBlockStatic() says, they *are* identified as block elements by the parser service.

Bug 1395828 (part 2) - Rename nsHTMLTags methods. r=mrbkap. The patch uses the nsParserService method names (minus the "HTML" prefix) because they are more descriptive. This will make it easier to replace nsParserService method calls with nsHTMLTags method calls. The patch also adds nsHTMLTags::AtomTagToId(), to match up with nsParserService::HTMLAtomTagToId().
