Bug 979649 - Part 3: Restore Windows clock drift in RTCP timestamp test. r=jib The Windows clock drift allowance was originally added for Windows XP (in bug 979649). I removed it in https://hg.mozilla.org/mozilla-central/rev/a1f769e90937 but it appears Windows 7 has the same clock drift problem that XP had.

Bug 1489301 - Part 6: Remove references to 'System' from WebIDL.py, r=bzbarsky 'Exposed=System' is no longer used in any webidl files, so we can kill it. Differential Revision: https://phabricator.services.mozilla.com/D9401

Bug 1489301 - Part 5: Expose all System-only objects on Window, r=bzbarsky There is a limited number of these, and this allows me to completely remove mention of the 'System' global. In the future System-only exposure could be achieved using a [Func] enabler. Differential Revision: https://phabricator.services.mozilla.com/D9400

Bug 1489301 - Part 4: Remove unnecessary [Exposed=System] annotations, r=bzbarsky We don't need to expose on both Window and System anymore, as Window now implies System. I don't remove unnecessary [Exposed=Window] annotations, as WebIDL upstream has removed PrimaryGlobal. Differential Revision: https://phabricator.services.mozilla.com/D9399

Bug 1489301 - Part 3: Fix test expecting interfaces not exposed on System, r=bzbarsky The `Window` interface is now exposed on system globals, so the check is now invalid. Differential Revision: https://phabricator.services.mozilla.com/D9403

Bug 1489301 - Part 2: Fix broken [Func] condition assuming Window object, r=bzbarsky This condition unwraps the global to a window, and doesn't check before dereferencing. This is no longer valid now that the corresponding interfaces are exposed on BackstagePass. Differential Revision: https://phabricator.services.mozilla.com/D9402

Bug 1489301 - Part 1: Expose Window interfaces on System by default, r=bzbarsky This is done by adding BackstagePass the exposure set of Window. Differential Revision: https://phabricator.services.mozilla.com/D9398

Bug 1500956 part 3. Fix our DOM pre-insertion checks to actually match the spec. r=smaug

Bug 1500956 part 2. Change our EnsurePreInsertionValidity implementation to follow the spec more closely. r=smaug This is basically putting in https://dom.spec.whatwg.org/#concept-node-ensure-pre-insertion-validity step 3 and moving step 4 to the right place in the order of steps. This matters, because step 3 throws a different exception from all the other steps.

Bug 1500956 part 1. Change IsAllowedAsChild to take an ErrorResult instead of returning a boolean. r=smaug The spec algorithms have a step that throws NotFoundError in between steps that throw HierarchyRequestError. We can't really implement that with our current setup. This changeset does not change observable behavior.
