Unify background placement code
Merges the implementations for background-image placement
from gradients and images. Add missing parts and fix bugs.
Now supported are the CSS properties:
* background-attachment (except for local value, see #19650)
* background-clip
* background-origin
* background-position-x/y
* background-repeat
* background-size
It should be noted that backgrounds are not clipped to
rounded border corners.
(This was done before but worked only in simple cases)
See: #19649
This solves the following issues:
closes#19626closes#16657closes#19482 (examples from http://lea.verou.me/css3patterns/ are rendered perfectly but the round border is completely ignored now)
closes#19577
- `./mach build -d` does not report any errors
- `./mach test-tidy` does not report any errors
I enabled a few tests with the first commit but I have written about a dozen manual tests I will try to turn into ref tests either before or after this patch lands.

Use background-size, background-position properties to render
CSS gradients.
Some cleanup in display_list_builder.rs related to gradient
calculations.
Adds two wpt tests for tiled gradients.
Note: For now even gradients with background-repeat: no-repeat
are repeated. Sometimes the gradient is not repeated everywhere.
Enable vars-background-shorthand-001.html CSS test.
The selection API only applies to certain <input> types:
https://html.spec.whatwg.org/multipage/#do-not-apply
This commit ensures that we handle that correctly.
Some notes:
1. TextControl::set_dom_selection_direction now calls
set_selection_range(), which means that setting selectionDirection will
now fire a selection event, as it should per the spec.
2. There is a test for the firing of the select event in
tests/wpt/web-platform-tests/html/semantics/forms/textfieldselection/select-event.html,
however the test did not run due to this syntax error:
(pid:26017) "ERROR:script::dom::bindings::error: Error at http://web-platform.test:8000/html/semantics/forms/textfieldselection/select-event.html:50:11 missing = in const declaration"
This happens due to the us of the "for (const foo of ...)" construct.
Per https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of
this should actually work, so it's somewhat unsatisfying to have to
change the test.
4. If an <input>'s type is unset, it defaults to a text, and the
selection API applies. Also, if an <input>'s type is set to an
invalid value, it defaults to a text too. I've expanded the tests
to account for this second case.
I had to change the test a little bit to avoid some failures due to
color and text both having a sanitizedValue which was making the test
use the first assertion instead of the second one in some cases.
The sanitize_value implementation is pretty simple, we iterate over the
content and checks that the content is 7 characters long, that the first
character is a `#` and then that all the following characters are
hexadecimal. If all those requirements are met, we lowercase the
content, otherwise we put `#000000` in it.
Make wdspec tests runnable
This makes it possible to run tests in tests/wpt/web-platform-tests/webdriver/tests and focus on investigating why they fail.

Continue http cache work
<!-- Please describe your changes on the following line: -->
Work in progress, and not quite worth a review yet. (Continuation of https://github.com/servo/servo/pull/4117)
TODO
- [ ] cache metadata (find some subset of`net_traits::Metadata` that can be shared across threads, it seems the problem is mainly stuff inside `hyper::header` in the `headers` field)
- [ ] determine which other fields of a `Response` need to be cached, so a full and valid one can be returned upon a cache hit.
- [ ] determine how to best share the cache across fetch threads (inside HttpState like I tried now?)
- [ ] Spend more time reading the spec and make sure the cache follows it where it matters.
- [ ] Make the current wpt tests pass.
- [ ] More...

Move assertions about the initial value of selection{Start,End} to their
own tests. This ensures that when one of these assertions fails, it
doesn't prevent other tests from being defined. Thus we have a clearer
view of which tests are passing or failing, since all tests get defined
regardless of which assertions fail.
