Bug 1385003 - Mark counter-style-rule-clone as failing from WR cset 921bde2. r?jrmuizel This was already marked fuzzy but now the difference between the test and reference images is even more pronounced. Technically this might still be fuzzable because the thickness of the text (which is what is different) is not what the test is testing for. But if we fuzz it the fuzz numbers would be so high that legitimate failures might get fuzzed as well, so it's better to just mark it failing for now and deal with it later.

Bug 1385003 - Autogenerated changes to go with webrender update. r?jrmuizel This regenerates the cargo lockfiles and FFI bindings header. It also revendors the third_party/rust libraries. MozReview-Commit-ID: FHNqyAcl5Em

Bug 1385003 - Use a different WebRenderAPI instance for each WebRenderBridgeParent. r=kats Previously, the WebRenderBridgeParent for each content layer tree would use the same WebRenderAPI instance as the top-level WebRenderBridgeParent for that window. However, in order to make the namespacing changes work we now need to use a separate WebRenderAPI instance for each WebRenderBridgeParent. The content WebRenderAPIs are cloned from the parent one, so that they all share the same backend, but can allocate resource IDs in distinct namespaces. MozReview-Commit-ID: 7VTFL8F09n7

Bug 1385003 - Update webrender bindings for API changes in WR cset f6d81d9. r?kvark In theory the upstream API change should allow us to share the same WR renderer instance across multiple WebRenderAPI instances. For now however I retain the existing behaviour of one WR instance for each WebRenderAPI instance, but keep track of the document id in a new DocumentHandle struct. The C++ side keeps a pointer to this DocumentHandle struct instead of the raw RenderApi. MozReview-Commit-ID: I9pCKOY1OYx
