To avoid calculate +/-infinite function value, we clamp it in the parser level.
Also, we use EnsureNotNan while calculating the interpolation for translate
function, so it's also better to do EnsureNotNan before call SetFloatValue()
while calculating the interpolation for rotate (AddCSSValueAngle) and scale
functions.

This adds support for #rgba and #rrggbbaa colors to CSS. This feature
is specified in https://drafts.csswg.org/css-color-4/#hex-notation .
This adds new types to nsCSSValue so that we can serialize the syntax
that was specified, as we do for other distinctions in how colors are
specified.
It does not change the behavior of the hashless color quirk, which
continues to support only 3 and 6 digit colors as specified in
https://quirks.spec.whatwg.org/#the-hashless-hex-color-quirk (step 4).
This changes property_database.js to remove various uses of 4 and 8
digit colors as invalid values. It then adds them in slightly fewer
places as valid values, but more thoroughly testing both initial and
non-initial values on 'color'.
It marks two canvas tests explicitly testing this feature as no longer
known to fail by removing their .ini files.
Finally, it adjusts the web platform test testing the hashless color
quirk to no longer treat 4 and 8 digit colors with hashes as invalid
values. Removing the relevant test items seems like the right thing
since they're in a section where 3 and 6 digit colors were skipped but
other lengths were tested. Modifying this imported test is OK since:

When we go to switch CSS Animations over to using
KeyframeEffectReadOnly::SetFrames we will need a way to represent any filled-in
from/to values as nsCSSValue objects. These objects are built from the current
computed style. We currently use StyleAnimationValue::ExtractComputedValue for
this which returns a StyleAnimationValue. In order to convert this to an
nsCSSValue we can use StyleAnimationValue::UncomputeValue. However, in some
cases, the nsCSSValue objects returned by that method are dependent on the
passed-in StyleAnimationValue object.
This patch adds an overload to UncomputeValue that takes an rvalue
StyleAnimationValue reference and produces an nsCSSValue that is independent
of the StyleAnimationValue through a combination of copying data and
transferring ownership of data.
This patch also adjusts the return value for the case of filter and shadow
lists when the list is empty so that we return a none value in this case.
These are the only list types which are allowed to have a null list value.
Not only does this produce the correct result when these values are serialized
(the initial value for 'filter', 'text-shadow', and 'box-shadow' is 'none') it
also means that UncomputeValue should never return an nsCSSValue whose unit is
null which is important because when we later pass that value to BuildStyleRule
it will treat a null nsCSSValue as an error case (specifically, "longhand failed
to parse").

The patch changes all uses of SizeOfIncludingThisMustBeUnshared() to
SizeOfIncludingThisIfUnshared(). This incurs the (tiny) cost of an unnecessary
IsReadonly() check for guaranteed-unshared strings, but avoids the possible
assertion failures that would occur when MustBeUnshared() was used incorrectly
on shared strings, which is an easy mistake to make.
We're violating http://www.w3.org/TR/CSS/#partial by leaving this
implementation in when we don't actually support the properties.
We're also incorrectly parsing marks and size in style rules rather than
@page rules; they were only intended for @page rules.
The only substantive change here, apart from a few variables changing in
size from uint16_t to uint8_t, is FontFaceSet's use of SheetType::Unknown
(0xFF) instead of 0 for FontFaceRecords for script-created FontFaces.
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.

When inspecting the specified value of {transition,animation}-timing-
function on a declaration, we should omit the start/end keyword in a
steps() value if it was omitted in the style sheet.
Since Keyframe.easing should reflect the {transition,animation}-timing-
function value relevant to each keyframe, we'll need to store on
nsTimingFunction the specific timing function value that was used, and
copy it down into ComputedTimingFunction for
KeyframeEffectReadOnly.getFrames() to access. This includes storing
whether the optional start/end keyword in a steps() function was
specified.
This makes it clearer that, unlike how SizeOf*() functions usually work, this
doesn't measure any children hanging off the array.
And do likewise for nsTObserverArray.
