So for everything but <length> and <length-percentage>, which have more complex
mechanics.
The pref is off for now of course.

So that extending it to support other math functions like min / max / etc is
simpler.
There should be no behavior change with this patch, though I added a comment to
some places where we don't do calc() clamping correctly (though other browsers
don't either so...).

Instead, subclass nsTextControlFrame. This simplifies the code and avoids
correctness issues.
I kept the localization functionality though it is not spec compliant. But I
filed a bug to remove it in a followup.

Although CssEnvironment is in Device of media query implementation, some code
creates CssEnvironment instance without Device. So I would like always to use it from Device of media query.

So that it takes one pointer instead of two, and doesn't make nsStylePosition's
size blow up.
This is not as ugly as I was fearing, thankfully, though it requires a bit of
boilerplate. I think it's acceptable.

I'm (sadly) about to make it a bit more complicated to pack it better. So we
may as well do this so it is easier to reason about navigate.
I also reordered things a bit, and removed some From<> implementations and
such.

This is needed to support min() / max() / clamp(), etc, as those need to be a
tree of values and thus need heap storage.
This unfortunately grows LengthPercentage to be two pointers, which is bad as
it blows up the size of nsStylePosition enough to trigger the size assertions.
This patch comments out the assertion for now, the follow-up patches will
uncomment them.

It is unexpected (see bug) that a -moz-box is affected by baseline alignment.
Make -moz-box be block-outside, and -moz-inline-box be inline-outside, instead
of the bespoke thing we have now.
This is more similar to everything else, and fixes the bug.

This cleans up and also allows us to keep the distinction between content: none
and content: normal, which allows us to fix the computed style we return from
getComputedStyle().
Do this last bit from the resolved value instead of StyleAdjuster, because
otherwise we need to tweak every initial struct for ::before / ::after.

Do the same we do for classes for now. We could be more precise and achieve a
bit more sharing with some more effort (left a comment there), but it seems
unlikely to matter in practice (and if we did that, we'd probably want to do the
same for classes).

This matches the new servo layout engine too, and thus removes some #[cfg]
gunk. Just use `flow` since it doesn't simplify the layout code as much.

Wip/rib/windows build fixes
These were minor changes I needed to make to build Servo on Windows based on following the existing instructions. In particular:
Even though I have C:\Python27 with python.exe in my PATH the build failed at some point when it failed to find python27.exe and I found that explicitly setting the PYTHON2 environment variable resolved this failure.
The end of the build failed to package MSVC redistributable DLLs and that was simply because I have a version (142) installed that wasn't checked for by build_commands.py.

Filter file: and about: responses opaquely
<!-- Please describe your changes on the following line: -->
file: and about: schemes were being treated like data: for cors purposes, when in fact they should have been subject to opaque response filtering. A comment indicated that this was necessary for some CSS tests, but I think the comment was out of date; the only tests depending on the unfiltered responses are unit tests that do not test any CSS functionality. I've updated those tests to now test for the opaque-filtering itself.

This makes it so that position:fixed elements do not scroll with the
rest of the contents, but does not tackle the rest of the issues with
their positioning.
Improve the name the NodeGeometryQuery
This query is used to get the clientTop, clientWidth, clientHeight,
clientLeft properties of DOM objects. "NodeGeometry" doesn't really
capture what these properties do as they often are returning the width
of an element's border.

Make HTMLFormControlsCollection rooted at the form's root, not rooted at the form itself
<!-- Please describe your changes on the following line: -->
We'd been misreading the first line of https://html.spec.whatwg.org/#dom-form-elements. The collection needs to be rooted higher than the form itself, so it can contain form controls elsewhere in the document with a form= content attribute. It is, as far as I can tell, unspecified whether "rooted at the form's root" is meant to live-update to a new root if the form is moved to another tree, and I'm assuming it doesn't have to.

Let EventSource fail fast on bad schemes
<!-- Please describe your changes on the following line: -->
EventSource went into an infinite reconnect loop in some cases where tests wanted it to go into a hard error state; this addresses the cases where that happens because the url isn't even http(s) and will thus definitely never result in an event stream.
https://github.com/web-platform-tests/wpt/issues/4311 suggests the tests might just be too picky here; the spec does use the word "may" on relevant behavior.
