switch gecko_bindings over to the gecko_debug feature [DO NOT MERGE]
...so that they use the correct Gecko structs regardless of whether Rust
code is being compiled with debug assertions or not.
This is the second part of the Servo-side changes for https://bugzilla.mozilla.org/show_bug.cgi?id=1357556
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes do not require tests because building is a sufficient test.

debug_assertions is not a reliable guide to whether Gecko C++ code is
being compiled with debugging assertions, since we can now compile Gecko
with --enable-optimize --disable-debug --enable-rust-debug: Gecko will
be compiled without debugging assertions (and debugging struct layouts)
and Rust code will be compiled with debug_assertions. The struct
mismatches in the binding layer lead to startup crashes.
This feature is not presently used, but will be set by some Gecko-side
changes and then used by some Servo-side changes. These changes need to
be made first so that CI on both sides works correctly at all
intermediate stages along the way.
stylo: Centralize stylesheet handling.
This is needed for both bug 1357461 and bug 1273303, where I plan to add smarter
invalidations than what we have now.
Also, it's cleaner.
Ideally I'll move this onto stylist, though that may require extra work to make
it work fine for Servo, so for now let's just do the obvious thing.

Upgrade to rustc 1.18.0-nightly (5f13a3b54 2017-04-15)
This version enables [struct field reordering][1] which brings the size of the types for specified values of some CSS properties under the threshold such that they shouldn’t be boxed anymore, making unit tests fail.
Simply unboxing them moves the test failure to Stylo’s unit tests, since the stable compiler used in that case does not do field re-ordering. Therefore, we manually reorder a couple fields to effectively bring this optimization to older compilers for a few specific types.

In particular, you can insertRule("@import url(\"already-loaded.css\");") and we
would try to clone the stylesheet, which without this change would borrow the
lock for reading.

Fix windows glutin keydown
<!-- Please describe your changes on the following line: -->
This fixes#12937 where keypresses arrive in a one-off fashion, effectively delaying each keystroke. This PR is based heavily on @codec-abc's https://github.com/servo/servo/pull/16193 PR, with some further fixes and cleanup. From the original PR comments:
> There are 2 types of events associated with keyboard: Key event (up or down) and Character Input.
>
> * A character is not necessary created one a key is pressed (like the home key).
> * A character may be created only using a combination of several key. For example, using a Qwerty International layout you have to type ` then e to get é. The first key press on ` will create no character.
> * In servo, we currently merge the 2 events together, meaning that we store a Character Input event in a field to fire a single event later on when we get a Key event.
>
> The order of events seems to be system dependent. For example, let's say that we type the A key on a Qwerty Layout. In Linux and MacOs we will get this:
>
> * Character Input for character A
> * Key down event with virtual key code of the key A
> * Key up event with virtual key code of the key A
>
> while in Windows we get:
>
> * Key down event with virtual key code of the key A
> * Character Input for character A
> * Key up event with virtual key code of the key A
>
> It seems that glutin make no attempt to reorder the event to make the order independent of the Operating System. I think it would be easier for Servo if it were handled by the library.
This fix is a stopgap for the current state of glutin. We may want to look into a deeper fix in the future. For now, this is hopefully adequate solution until a more permanent one can be found.
This is the last remaining issue for the Windows nightly blockers meta-issue https://github.com/servo/servo/issues/12125

stylo: Bug 1343753 - Use ComputedValues while updating transitions in Gecko
These are interdependent patches of Bug 1343753. We want to use ComputedValues and AnimationValues to start/update/stop the transitions.
