Not the prettiest, but it will work, and LengthPercentage will be 12 bytes which
is pretty good (we could do better if wanted I guess):
* Au(i32) length;
* f32 percentage;
* AllowedNumericType(u8) clamping_mode;
* bool has_percentage;
* bool was_calc;
This will allow me to start moving C++ stuff to use this representation.

This patch implements -moz-gtk-csd-hide-titlebar-by-default media query
to check if the system titlebar should be disabled by default on Linux systems
(it's already disabled on Window/Mac).
It also removes explicit definition of browser.tabs.drawInTitlebar preference on Linux.
When browser.tabs.drawInTitlebar is missing the -moz-gtk-csd-hide-titlebar-by-default
is used to obtain the titlebar state. When browser.tabs.drawInTitlebar is set
in about:config or by Customize menu, the user peference is used instead of the default.
It also fixes a -moz-gtk-csd-available media query,
it was always true regardless the actual system setting.

The only reason it was on style_traits is so that they could use it from some
other crates, but Servo eventually ends up getting the value from an integer, so
may as well pass it around and do that in the end of the process anyway.

Based on https://bugzilla.mozilla.org/show_bug.cgi?id=1348519#c6 and
https://github.com/w3c/csswg-drafts/issues/3201:
Currently grid-template-rows/columns interpolate “per computed value”, which
means that if the number of tracks differs, or any track changes to/from a
particular keyword value to any other value, or if a line name is added/removed
at any position, the entire track listing is interpolated as “discrete”.
But we "agree" with two more granular options:
1. Check interpolation type per track, rather than for the entire list, before
falling back to discrete. I.e. a length-percentage track can animate between
two values while an adjacent auto track flips discretely to min-content.
2. Allow discrete interpolation of line name changes independently of track
sizes.
Besides, for the repeat() function, it's complicated to support interpolation
between different repeat types (i.e. auto-fill, auto-fit) and different repeat
counts, so we always fall-back to discrete if the first parameter of repeat()
is different.

This restores the previous behavior of using calc().
Note that background-position / object-position, which test this, weren't
hitting the assertion because they use another codepath.
I didn't add more extensive tests for this because it's well tested for those
two properties, and because this is legacy anyway, see the comment in the test.
I did add the assertion to the codepath those two properties hit.

It does not represent `<length> | <percentage>`, but `<length-percentage>`, so
`LengthOrPercentage` is not the right name.
This patch is totally autogenerated using:
rg 'LengthOrPercentage' servo | cut -d : -f 1 | sort | uniq > files
for file in $(cat files); do sed -i "s#LengthOrPercentage#LengthPercentage#g" $file; done

This is a first step to share LengthOrPercentage representation between Rust and
Gecko.
We need to preserve whether the value came from a calc() expression, for now at
least, since we do different things depending on whether we're calc or not right
now. See https://github.com/w3c/csswg-drafts/issues/3482 and dependent bugs for
example.
That means that the gecko conversion code needs to handle calc() in a bit of an
awkward way until I change it to not be needed (patches for that incoming in the
next few weeks I hope).
I need to add a hack to exclude other things from the PartialEq implementation
because the new conversion code is less lossy than the old one, and we relied on
the lousiness in AnimationValue comparison (in order to start transitions and
such, in [1] for example).
I expect to remove that manual PartialEq implementation as soon as I'm done with
the conversion.
The less lossy conversion does fix a few serialization bugs for animation values
though, like not loosing 0% values in calc() when interpolating lengths and
percentages, see the two modified tests:
* property-types.js
* test_animation_properties.html

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.

Replace LengthOrPercentage with NonNegativeLengthOrPercentage on
ShapeRadius, Circle, Ellipse. And derive ToAnimatedValue for ShapeSource and
its related types, so we clamp its interpolated results into non-negative
values. (i.e. The radius of circle()/ellipse() and the border-radius of
inset().)
Note: We may get negative values when using a negative easing function, so the
clamp is necessary to avoid the incorrect result or any undefined behavior.
