This commit introduces a new preference option
mathml.nonzero_unitless_lengths.disabled to disable MathML nonzero unitless
values like "5" for 500%. MathML nonzero unitless are now disabled by default
but it could be easily enabled again later if we decide otherwise.
* test_bug553917.html is updated to check that these values now cause an error
message to be logged into the console rather than a deprecated warning
when nonzero unitless lengths are disabled.
Additionally, the test checking invalid double dots "2..0" is updated not
to use unitless syntax.
* The old test 355548-3.xml checks support for mathsize names and also uses
several features that are going to be deprecated. So it is just run with
the proper preference adjustment.
* mfrac-linethickness-2.xhtml and number-size-1.xhtml check support for
unitless lengths so they are now run with that support enabled.
* WPT tests frac-linethickness-001.html and lengths-1.html are executed with
the some MathML features disabled in order to make them pass.
We get more assertion passing for the "Legacy numbers" test of
lengths-2.html ; however there are still some issues to address
(see bug 1574751).

This commit introduces a new preference option
mathml.mathsize_names.disabled to disable mathsize keyword values. For
now, these are only disabled in Nightly builds.
* test_bug553917.html is updated to check that these values now cause an
error message to be logged into the console when mathsize names are used
and the feature disabled.
* The old test 355548-3.xml checks support for mathsize names and also uses
several features that are going to be deprecated. So it is just run with
the proper preference adjustment.
* mathml/relations/css-styling/mathsize-attribute-legacy-values.html passes
after this change so the test is run with the mathsize names disabled too
and the failure expectation is removed.
* mathml/relations/css-styling/mathsize-attribute-css-keywords.html is added
to check that CSS keywords won't be supported when we switch to using the
CSS parser in the future. This test passes now when the "small" keyword
is not accepted so it is run with the mathsize names disabled too.

This commit introduces a new preference option
mathml.mfrac_linethickness_names.disabled to disable linethickness names. For
now, these names are only disabled in Nightly builds. Announcements and actual
disabling of this and other MathML features will be considered later.
* test_bug553917.html is updated to check that these values now cause an error
message to be logged into the console.
* mstyle-1.xhtml is updated to use a numeric linethickness since the point of
the test is just to check that the attribute is not supported on mstyle, not
about the actual attribute value.
* Other fractions tests relying on linethickness names are executed with the
proper preference adjustment.
* mathml/presentation-markup/fractions/frac-linethickness-001.html is now
closer to its expectation ; however the test still fails because nonzero
unitless values are not removed yet. See

It was remaining from an earlier iteration of bug 1418425 that uses
zlib's crc32 function, but ended up unused because in the end it was
done differently.
Interestingly, the corresponding host objects are not built currently,
and actually fail to build when built manually (or with build system
changes that make them built).

The main part of the change is the change to ChildSHistory - make it possible to have Go() to be called asynchronously
and also let one to cancel pending history navigations. History object (window.history) can then use either the sync or
async Go(), depending on the dom.window.history.async pref.
LoadDelegate, which is used by GeckoView, needs special handling, since
it spins event loop nestedly. With session history loads and same-document loads we can just
bypass it.
To deal with same-document case, MaybeHandleSameDocumentNavigation is split to IsSameDocumentNavigation,
which collects relevant information about the request and returns true if same-document navigation should happen,
and then later HandleSameDocumentNavigation uses that information to trigger the navigation.
SameDocumentNavigationState is used to pass the information around.
referrer-policy-test-case.sub.js is buggy causing tests to pass only on Firefox with sync history API.
nested-context-navigations-iframe.html.ini is added because of https://bugzilla.mozilla.org/show_bug.cgi?id=1572932

As a result of the expansion, position:fixed elements are attached to the
expanded layout viewport.
The expanded value is used behind a pref which is enabled by default on nightly
initially, and the pref will be fliped in bug 1571599 on other channels.
scrollbars-in-landscape-content.html still fails since the vertical overlay
scrollbar doesn't appear since we are not yet using the expanded value during
reflow to tell whether we need overlay scrollbars or not. This will be fixed
by the next commit.
