Bug 1686494 part 2: When gathering printed canvas elements for PDF.js, skip canvases on pages that aren't in the user's custom print range. r=TYLin

This code currently does a recursive tree-traversal to get a list of all canvas
elements that might be used for PDF.js content, so that we can invoke the
appropriate callbacks on them to let PDF.js prepare for printing.

In this patch, I'm adjusting the outermost level of that traversal to make it
aware of the fact that PrintedSheetFrames may now contain many skipped
nsPageFrames whose content we don't want to render.

Bug 1686494 part 1: Change return type of nsPageSequence::GetCurrentSheetFrame to the actual concrete type, PrintedSheetFrame*, instead of nsIFrame*. r=TYLin

This patch doesn't change behavior; it just adds a static_cast to a
more-specific type that we know the variable has, and updates the signature and
callsites.

(The next patch will make use of the fact that we know this type.)

As is the case with GTK, Android provides an OS override to display times in
AM/PM or 24 hour format. This moves the code for rewriting skeletons from the
GTK specific code to OSPreferences, and calls it from the Android OSPreferences
implementation.

This was tested manually by visiting the file:/// uri. I don't believe this is
feasible to test from automation, as it would require changing Android OS settings
from within our test code.

This patch is a minor cleanup based on prior feedback to make all of IOUtils

RunOnBackgroundThread has been renamed to RunOnBackgroundThreadAndResolve. The
body dealing with calling InvokeAsync for calling a function on the background
event target and returning a MozPromise has been refactored into a new
function, RunOnBackgroundThread.

This allows us to have more complicated IOUtils methods that do not simply
resolve their promises to whatever is returned by the background methods.

This patch adds two tests, one for the mochitest and another for WPT.
Both tests will test the case of loading the about:blank page. And
mochitest tests the case of setting document.domain additionally.

The WPT framework won't support testing the document.domain case, so
there is no such test in the WPT.

Bug 1685807 - Part 1: Not to reset the window.name if it's navigating to an about:blank page from a non-about:blank page. r=smaug

This patch changes the checking condition about the cases that we don't
need to reset the window.name.

Also, we take the domain into account when checking the principals of
the old and new documents. This would make the window.name to be
reset if the document.domain was changed to a cross-origin.
