While looking at moving the flag around I realized that the only reason
we have FontMetricsProvider and co is because we didn't have access to
the per-document font-prefs cache. That's trivial to fix tho, so do
that and simplify the setup for font queries even more.

The math-depth implementation is refined to take into account the
ScriptPercentScaleDown and ScriptScriptPercentScaleDown constants (if the
parent's first valid font has a MATH table) in order to calculate the
scale factor between math-deth 0 and 1, and between 0 and 2 respectively.
Behavior is unchanged if the legacy scriptsizemultiplier attribute is
specified or if no MATH table is available.
The preference layout.css.math-depth.enabled remains disabled in nightly
until the remaining bit (support for font-size: math) is implemented in
bug 1667090.

These are gated by the same layout.css.font-tech.enabled pref as the
closely-related `tech()` function for the @font-face src descriptor;
once the spec questions are settled, we should enable them all together.

This patch will use the width/height attributes from <source> to override
width/height/aspect-ratio CSS property values of <img> elements.
So basically, we need to introduce an extra nsMappedAttribtue member in
HTMLSourceElement (and it only stores width and height attributes).
And then we use it as an extra declarations (which are generated by
Gecko_GetExtraContentStyleDeclarations()) so we can override the
declarations created from presentation attributes of <img>.
Besides, we need to make sure <img> elements get restyled in the
following cases:
1. width/height attributes is changed in <source> elements
2. <source> is inserted as a <picture>'s child
3. <source> is removed from the child list of <picture>
4. <img> is inserted as a <picture>'s child
5. <img> is removed from the child list of <picture>
We make the responsive source synchronously get updated in the previous patch,
so now we can just restyle the image when updating its responsive source.
Note: We fix the reflection of percentages for width/height attributes in
the next patch.

gfxFontCache acquires and releases its mutex during various operations.
In order to keep the state internally consistent, we should only release
the lock after the full operation is complete. This involves moving the
deletion of gfxFont to outside the lock via a temporary discard array.
The expiration state should not be protected by the gfxFont's mutex
since we don't hold it during most operations. Instead we should hold
gfxFontCache's mutex because then we can guarantee the operation is
atomic, particularly when a worker wants a font, and the main thread is
aging the generations.
When a font is returned from gfxFontCache, we now return it already
removed from the tracker, and with its refcount updated. This avoids any
potential races between the expiration timer and a worker accessing the
font, as well as simplying the callers so they don't need to be aware of
addref-ing manually in case the result is to be discarded (so that it
gets readded to the tracker).

So we can specify the keyframe-specific composite operation. However,
these is a spec issue about the default composite for CSS Animations:
https://github.com/w3c/csswg-drafts/issues/7476.
I choose to use auto as the default composite for missing keyframes to match
the definition in web-animations-1 because I think this makes more sense:
> If the keyframe-specific composite operation for a keyframe is not set, the
> composite operation specified for the keyframe effect as a whole is used for
> values specified in that keyframe.

Now that cbindgen and rust support const generics, it seems more simple.
This centralizes all the relevant font constants etc in rust and avoids
conversions when going from rust to C++ and vice versa.

Add a dom/base/rust crate called just "dom" where we can share these.
Most of the changes are automatic:
s/mozilla::EventStates/mozilla::dom::ElementState/
s/EventStates/ElementState/
s/NS_EVENT_STATE_/ElementState::/
s/NS_DOCUMENT_STATE_/DocumentState::/
And so on. This requires a new cbindgen version to avoid ugly casts for
large shifts.

This is a "simplified" implementation of 'ic', similar to what Safari Preview
currently supports: it only considers the advance of U+6C34 if found in the
first available font, and otherwise falls back to the default of 1em.
(The spec allows for this "in cases where it is impossible or impractical to
determine the ideographic advance measure".)

.fallback is always the default font for the lang group unless we're a
system font (in which case it's "none").
The only reason we need that is because we need to react to
language changes (which affect the initial font).
Simplify the model a bit doing the language lookup in gfxTextRun (this
should avoid allocating a few nsStyleFont structs too.

This seems like more sensible behavior. We have another use of
only_generic(), but that affects font sizing and other browsers agree
with us there:
<div style="font-family: monospace">Should be 13px</div>
<div style="font-family: something, monospace">Should be 16px</div>
So not touching that one.

Use the same document state mechanism we have for :moz-locale-dir. Also,
simplify the setup of the later to be the same as :dir(), allowing the
matching code to be less repetitive.
This should fix some flakiness in chrome mochitests, but we have no existing
tests for these pseudo-classes more generally and since they're just
chrome-only I'm not super-excited about adding more.

This moves the style-specific bits of the shared style sheet cache into
a super-class, and leaves the generic "sub-resource management" bits
inside a base class. In order to implement it you need to provide some
types, mainly:
* Loader, which implements LoaderPrincipal() and allows you to key per
principal. The idea is that this would be the
{CSS,Script,Image}Loader object.
* Key (self explanatory). We might want to introduce a common key to
share the cache partitioning logic.
* Value, which represents the final cached value. This is expected to
be a StyleSheet / Stencil / imgRequestProxy.
* LoadingValue, which must inherit from
SharedSubResourceCacheLoadingValueBase (which contains the linked
list and the state that the cache manages). It also must provide a
ValueForCache() and ExpirationTime() members. For style, this is the
SheetLoadData. For script this will probably be the
ScriptLoadRequest. For images it might be enough with the
imgRequestProxy, but we might need something else, haven't looked
into it too deeply yet.
We move the use counters into the stylesheet since that's both more
similar to how we treat StyleSheetContents and easier (that way we don't
need to add some sort of "extra data" thing to the cache).
