We need another flag that represents allow-negative-number for SMIL, so
this enum will also comprise the another parsing mode that allows negative number.
explicitly specify bitness for x86 cross-compilation situations
Despite compiling for architecture X, the user may have specified a
clang that defaults to architecture Y. We need to ensure that we invoke
clang with the correct architecture selection. We do not use --target
to do this, however, because that runs into problems with LLVM's default
search paths. For the x86 case, we can simply use -m$BITNESS to select
the correct architecture.
This is not at all a general solution, but it does unblock compiling Stylo for 32-bit Linux on Gecko's infra.

I've chosen this approach mainly because there's no other good way to guarantee
the model is correct than holding the snapshots alive until a style refresh.
What I tried before this (storing them in a sort of "immutable element data") is
a pain, since we call into style from the frame constructor and other content
notifications, which makes keeping track of which snapshots should be cleared an
which shouldn't an insane task.
Ideally we'd have a single entry-point for style, but that's not the case right
now, and changing that requires pretty non-trivial changes to the frame
constructor.

Generate atom files at build-time
The commits here basically do the following things:
1. move all generated files for gecko into "gecko/generated" so that we can copy all of them around
2. make regen_atoms.py generate file to the out dir rather than in-tree
3. make the build script invoke regen_atoms.py when bindgen feature is enabled

Text style is always resolved via ServoStyleSet::ResolveStyleForText, either
from the frame constructor initially, or from
ServoRestyleManager::ProcessPostTraversalForText.
So text-only adjustments should go there instead. Since that doesn't call into
cascade(), all the code that passes `pseudo` there is dead code we can remove.

1. We add a new arm to TransitionProperty, TransitionProperty::Unsupported,
which contains an Atom, so it's better to remove the Copy trait from
TransitionProperty.
2. TransitionProperty::Unsupported(Atom) represents any non-animatable, custom,
or unrecognized property, and we use Atom to store the ident string for
serialization.
In Gecko, we use double pointers to nsBorderColors to store -moz-border-*-colors.
We can simplify the implementation of computed value in Servo by using Option<Vec>.
As to passing computed values from Servo to Gecko, we might need to use some
binding functions (pre-added in the same Gecko bug, see Bug 1348173).
Note that we added -moz-border-*-colors as sub_properties of the 'border'
shorthand, so we can make the 'border' shorthand reset -moz-border-*-colors
(See Gecko Bug 482692). However, since they are Gecko only non-standard properties,
we should skip these sub_properties while doing unit testing in Servo. The test part
should be convered by Stylo/Gecko already.
A bit refactoring of replacing all ["top", "right", "bottom", "left"] with PHYSICAL_SIDES
is included in this patch, since we've already had PHYSICAL_SIDES for a while.

Recent change in bug 1277709 makes ThreadSafeAutoRefCnt start using std::atomic, which somehow doesn't not have #[derive(Debug)] on Windows, which makes all objects which includes ThreadSafeAutoRefCnt to stop having #[derive(Debug)]. This breaks stylo build on Windows.
By adding it as an opaque type, std::atomic would derive Debug again.
Two functions added in this patch get progress value from ComputedTiming
or get the position in a given AnimationPropertySegment.
Without these FFIs, we need to expose Maybe<> and Nullable<> and handle
them in Rust.
The UpdateAnimationsTasks is a bitflags and each bit is generated from
Gecko's UpdateAnimationsTasks (enum class) values for matching values
between C++ and Rust. For this reason, the bitflags is annotated as
(feature = "gecko"), as a result update_animations() which uses this bitflags
also became gecko-only function.
