The tests for Bug 1133905 all compare the visibility of scrollbars with
differently-sized css viewports. This patch has some affect on the
viewport sizing that I don't understand, and it causes some of the tests
to start passing and some to start failing.

The test for Bug 12421722 has elements sized to height 100% and checking
for the presence or absence of scrollbars. In this case the patch appears
to increase the css viewport height and decrease the width -- again for
reasons I don't understand -- and this affects the scrollbar sizes.

Testing the initial value of innerWidth and innerHeight is not really viable when
the visual viewport has been set by the opener, but constrained by the device.
The returned value differs between the desktop and mobile browsers because of the
device constraints. The simplest thing to do is to test the CSS viewport and
ensure that the innerWidth values can be set.

The old vector recycler had a few problems:
  1. shrinking to fit would be inevitably followed by re-allocation, since it's unlikely that the consequent sizes are below the immediately followed frames
  2. shrinking before clearing means that the existing contents are copied over, which is a waste

The new code has more complicated logic for recycling, aimed at reducing heap allocations. It's also collecting the statistics.

The unittest/user.js file contained a mix of preferences that ensure tests can run (switching web services to dummy servers to prevent hitting networks, etc) and preferences that enable features that aren't shipping by default (turning on touch events, enabling experimental css features, etc).

In the future, we're going to want to run tests of only the features that are being shipped in release builds (or in beta builds, or in esr builds, etc), so we need to move feature-enabling preferences into a different file to make it possible to run tests with various sets of features enabled.

This commit just moves feature-enabling prefs into a new file and then includes that file everywhere unittest prefs were already being included, so it should have no functional difference in the set of preferences being set in test runs.

When scroll frames are created, and no explicit parent is provided,
the old code used to take the ClipID from the c/s stack. The stack
has been removed on WR side, and this parent assignment got lost.

This change takes the SpatialID from the top of the stack on Gecko
side to replicate the old behavior.

The autoplay checking for media element has 4 different phases,
1. check whether media element itself meets the autoplay condition
2. check whethr the site is in the autoplay whitelist
3. check global autoplay setting and check wether the site is in the autoplay blacklist.
4. check whether media is allowed under current blocking model (click-to-play or user-gesture-activation)

Bug 1509717 removed Gecko's definition of StyleBorderStyle to use the Rust one.

The Rust version was ordered in a different way, and the table code relied on
the order in order to build the mapping for border conflict resolution.

Simplify this mapping now that border constants are ordered in terms of
priority, see the comment on top of `enum BorderStyle`.
