Bug 1411627 - Add reftests. r=mstange MozReview-Commit-ID: apbFCe2uzF

Bug 1411627 - Send the applied offset for sticky frames to WR. r=mstange There are cases where we do a main-thread paint at a scroll position where sticky offsets have been applied in order to keep sticky items visually unmoving. From that paint, it's possible to do an async-scroll in the direction that reduces the sticky offset. In order for WR to handle this case properly we need to tell WR how much of a sticky offset was already applied on the main thread. MozReview-Commit-ID: 79DsfPpsIfA

Bug 1411627 - Stop sending sticky clips to WR for scrollframes with no ASR. r=mstange If the scrollframe has no ASR and is not async scrollable, WR will never need to adjust the position of the sticky item. So we don't actually need to send this data to WR. In theory this would be harmless but the later patches in this bug actually expose another coordinate space mismatch between the gecko and WR sticky-position code, so this patch is needed to avoid the latent problem from manifesting to the user.

Bug 1414096 - Remove support for nsISupportsString values in nsPrefBranch::{get,set}ComplexValue(). r=florian. Bug 1345294 introduced nsPrefBranch::{get,set}StringPref(), which allowed the getting of utf8 strings from prefs, which previously required using nsISupportsString with {get,set}ComplexValue. That bug also converted most uses. This patch finishes the job. - It removes the nsISupportsString support. - It converts existing code that relied on the nsISupportsString. - It removes the lint that was set up to detect such uses of nsISupportsString.
