Bug 934640 - Let 'Ensure that databases() returns a promise' test case accept a rejected Promise to match its description. r=dom-workers-and-storage-reviewers,ytausky

Before the patch, the test failed if indexedDB.databases() returns a promise, but the promise was rejected. This was not what "Ensure that databases() returns a promise." describes. Therefore, either the description should be changed, or the test. But there are other tests that check if the promise is resolved, I changed the test.

Overall, the new RDM is using dark theme styling as before. The only exception is the text in the actual toolbar React component, which seems to default to using light theme colors. This revision applies a CSS variable `theme-body-color` to the toolbar's document body to toggle between dark/light theme colors for text.

Bug 1600488 - Allow FinalizationGroup targets to be unregistered after they have been queued for cleanup, in accordance with the spec r=sfink

The fix is to queue pointers to finalization records rather than just holdings when the target dies.  These are still in the resgistration map and so can be cleared by unregister().  We detect this in the iterator's next() method and skip any such records.

This patch adds a new context for the performance-new components. It's
eventually the only place where the settings will live, but for now
the components share the settings between the popup, the devtools panel,
and the about:profiling page.

This page uses the base styling that the preferences page uses. The styles
should obey the theming for the browser, and ignore the devtools theming
colors.

This is probably the biggest change to the existing components, as it makes the
summary dropdowns conditional based on the page context. This keeps the old
workflow working, but allows for the new about:profiling page's design. Most
of the diff here is creating the new _renderSection method which consolidates
this logic, and also handles the summary div structure.

The new about:profiling page creates some more complexity around what
the page context is. It is simpler to handle the different cases with
a union, rather than booleans.

SABs become foreground-finalizable so that we can access the runtime
during finalization.  Then a simple counter on the runtime will track
live SABs for the runtime, and the predicate on the context can get
its information from the runtime.

Fallout: SABs are now enabled on the globals used for jsapi-tests.

Some OpenGL ES implementations do not like how we overflow a signed
32-bit integer when masking what are otherwise really unsigned 32-bit
integers. This patch avoids the problematic mask and instead just
does an equivalent shift.

Historically there were kludges in how we chose to snap layers and
transforms, nominally for performance reasons (see bug 602200 comment
36). WebRender appears to render what was considered at the time the
ideal outcome, which also makes the most sense as a content author.
Given we are otherwise lacking a reason to continue with the old
behaviour, this patch adds a new test case to confirm WebRender snaps in
the ideal fashion, and non-WebRender does not.

Bug 1601219 - Use the right PageStyleFront instance when querying computed styles from the color picker; r=rcaliman

It looks like we left out some places in the inspector when we made it fission-compatible.
The color-picker, in particular, needs access to the selected node's computed style for its
color contrast logic.
We used to access this on the top-level target PageStyleFront. We just need to change this so
it uses the one contextual to the selected node.
