In this patch, we implement nsIDOMWindowUtils::GetUnanimatedComputedStyle
which returns computed value of given CSS property without animation rule. This
method is used from the DevTools animation inspector to fill in keyframe values
when the property value is null (indicating that the underlying/base value is
being used).
In order to implement this, we extend nsComputedDOMStyle constructor to fetch
the computed style minus animation style (i.e. the base style). This is somewhat
complicated by the fact that for discrete animation.
StyleAnimationValue::ExtractComputedValue may return ‘unset’, ‘initial’ or
‘inherit’. For example, if the author uses the 'unset' 'initial' or 'inherit'
keyword for a discrete property (e.g. 'align-content’), ExtractComputedValue
returns the keywords as-is. Furthermore, if the user does not set any specific
keyword, ExtractComputedValue returns ‘unset’. We use this new
nsComputedDOMStyle mechanism to resolve these keywords into a valid keyword for
computed style in the same way as other properties (e.g. ‘opacity’).

There are currently no call sites of GetStyleContextWithoutAnimation
but there are a couple of places (including this patch series) where we would
like to use such a method, but without the flushing behavior.
This patch drops the flushing from GetStyleContextWithoutAnimation and
renames it to GetUnanimatedStyleContextNoFlush. It also makes a few other minor
tweaks:
* Adds the aStyleType parameter for consistency with GetStyleContextNoFlush and
GetStyleContext
* Moves the implementation of this method and GetStyleContextNoFlush to the
header file since they simply wrap DoGetStyleContextNoFlush.
* Changes the order of these declarations so that the more specialized method
comes later.
* Drops the comment describing the method since both the method name and the
inline definition should now make it obvious what it is doing.
(Actually making this method not return animation styles when it re-uses an
existing style context will happen in the next patch.)

In the next patch we want to add a method called
GetUnanimatedStyleContextForElementNoFlush but that's much too long. Instead it
seems better to just drop 'ForElement' from all these methods since it should be
fairly obvious we are getting the style context for an element given that the
first argument is an element.

We need another variant of GetStyleContextForElement() that does not consider
animation rules at all to get the base styles of the target element (i.e.
styles without animations).
In subsequent patches we also skip nsAnimationManager::UpdateAnimations() and
EffectCompositor::UpdateEffectProperties() to avoid (indirect) recursive calls
for resolving style of the same element.

Because the new function checks types, we need to change the fullCorner type
in nsComputedDOMStyle::GetEllipseRadii() and
StyleAnimationValue::ExtractComputedValue() from uint8_t to |Corner| to fix
build error.

This patch is written with the help of the following script.
function rename() {
find .\
-type f\

! -path "./.hg"\
\( -name "*.cpp" -or\
-name "*.h" \)\
-exec sed -i -e "s/$1/$2/g" "{}" \;
}
rename "css::Side" "Side"

I have to move the definition of StyleBasicShape and StyleShapeSource prior to
where nsStyleDisplay::mShapeOutside is defined since the template struct need to
be fully defined before using as a member variable.
Use SetIdent() in CreatePrimitiveValueForBasicShapeOrURL() in
nsComputedDOMStyle.cpp per bug 1288626 comment 6.
