Relying on the implicit conversion by `::FromContent` doesn't work for
us because we inherit that from `nsGenericHTMLElement` and isn't specific
to `HTMLAreaElement`, so it would accept other elements.
This also updates the Attribute changed event handler to exclude `<a>`
elements and cleans up an unused variable from the old code.
This was part of the HTML4 standard but only ever implemented by Mozilla
and removed again in HTML5 due to lack of adoption. Retaining this could
cause web compat issues and unspecified behavior in the layout engine.
This allows for two-location color stops (`color x% y%`) which is shorthand
for `color x%, color y%` where both colors are equal. (pct/length accepted)
See code comment for the reason it's implemented the way it is.

A grid item spanning multiple grid rows/columns which include a flexible
track should not participate in the auto min-sizing calculation.

This removes a lot of the plumbing for having the platform embed itself
through IPC which was required for B2G running the browser as both
shell and browser application.
However, `-moz-outline-radius` should still override any `border-radius`.
This is primarily done for backward compatibility with some themes.
Additionally, it also allows for more advanced outline control than the CSS spec provides, without breaking spec.
Finally, if the spec is ever updated to include `outline-radius`, we'll be ready to drop the `-moz-` prefix!
Note: BZ 315209 has an inadvertent double-negative in nsDisplayList.cpp:
HasRadius() essentially returns the opposite value it should.
Note: Because the new function checks types, we need to change the
fullCorner type in `nsComputedDOMStyle::GetEllipseRadii()` and
`StyleAnimationValue::ExtractComputedValue()` to `Corner` instead of the
underlying base type.
- Renames it to NS_CSS_FULL_CORNERS and uses the one macro for all full
corners. In preparation for giving half corners the same treatment.
- Swaps to prefix operator++
To avoid confusion with mozilla::css::corner, rename ::Corner to
mozilla::LogicalCorner, and move it to nsStyleCoord.h from the illogical
nsCellMap.h location.
Also, append the LogicalCorner prefix to all the enum values, to match
the surrounding coding style.
For the time being, because we don't have `revert` yet, we should force
normally hidden elements to be hidden, so they aren't revealed by sites
using the bad practice of `*{ }` style blanking rules but then using
`revert` to re-hide them.
