Prevent crashing when a link tag has two or more in-flight requests (fix for issue #15101)
<!-- Please describe your changes on the following line: -->
The `HTMLLinkElement::set_stylesheet` function now checks whether there already is a stylesheet, and if there is, calls `Document::invalidate_stylesheets` after modifying `self.stylesheet`.
This PR also includes a minimal WPT that causes the panic.
This is fundamentally a timing issue, so while this fix prevents the crash, it does not fix the underlying issue. Making a <link> element send a second request before the first can finish and then getting the two stylesheet responses out-of-order will apply the wrong stylesheet, as demonstrated with https://gist.github.com/SwagColoredKitteh/2c24c7fac635445042eda4a30e10420e.

@jdm I thought it would be better to make a PR for my local changes anyway, since you wanted it :)

We try to get the servo animation rule and declarations during elements
matching, and put the rule to the right priority.
Note: According to CSS Cascade Level spec, Animations is between
Important author declarations and Normal override declarations.
We use TElement::get_animation_rule to get the animation rules from
Gecko side, which contain the interpolated values of the specific
element and the pseudo type.
This way we'll be able to take different paths for the sequential and parallel
traversals in some concrete cases.
This is a preliminar patch to fix bug 1332525.
Ideally this would be lazy, but eventually we're going to need to restyle in
RebuildAllStyleData anyway, which would require us to have the style up to date,
so no need to complicate our lives.

Fix margin size calculation for TableWrapper
<!-- Please describe your changes on the following line: -->
Fixes inline size calculation for TableWrapper. The table's width was always reaching the inline size equation solver as a specified variable, which was causing the system to be overdetermined when there was a margin specified for the table, and this caused the overflow reported in #12748. The fix consists in handling three cases when the table's width is not specified: if the preferred size of all columns fits, it is returned; if the minimum size does not fit, it is returned instead (it will overflow), otherwise, it is returned as a free variable (that should be solved together with the margin to some value above the minimum width and below the preferred width).

Implement home end key scrolling
<!-- Please describe your changes on the following line: -->
* Refactor all scroll related code to use a new `ScrollLocation` struct which can either be a `delta` (as before) or a `Start` or `End` request, to represent the desire to scroll to the start and end of the page.
Effectively, everywhere a delta was used, there is now a `ScrollLocation` struct instead.
* Add key press listeners for HOME and END keys so as to cause a scroll to be queued with `ScrollLocation::Start` (in HOME case) or `ScrollLocation::End` (in END case).
* These changes depend on added support for the new `ScrollLocation` in webrender and webrender_traits. See https://github.com/servo/webrender/pull/540.

Added compiletest to verify TrustedPromise does not implement Clone
As per issue: https://github.com/servo/servo/issues/14500
I have added a test to ensure that TrustedPromise does not implement Clone.
This is my first PR to the project, so feedback in terms of both code and the actual PR would be very welcome.
Thanks,
Verlet64
