Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

After StyleBasicShape is set to StyleShapeSource, it's life cycle never go
beyond StyleShapeSource, so I make StyleBasicShape hold by a UniquePtr in
StyleShapeSource.
Also, replace all raw pointers to StyleBasicShape by UniquePtr in all APIs.

The original operator==() (implemented by EqualsInternal<true>) is not been
used. Therefore, I expand EqualsInternal<false> into it, and move it to
nsStyleStruct.cpp.
Also, use DefinitelyEqualURIs() in nsStyleStruct.cpp in operator==().

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

This property accepts a color. It's inherited and defaults to transparent.
Its value is respected on macOS when rendering text into transparent pixels.
This property should be used for text that is placed on top of "vibrant"
-moz-appearances, in order to achieve high quality text rendering for such text.
In most cases, the property should be set to a named system color; an upcoming
patch in this patch series will add one such color for each vibrant
-moz-appearance value.
However, in some cases it can also be useful to use a custom color: If text
is rendered into an intermediate surface, for example because a mask is applied
to it, and the background color behind that intermediate surface is known, then
this property can be set to that background color in order to achieve subpixel
AA for the text inside the mask effect. In that case, the font smoothing
background color is respected because text is rendered into transparent pixels
*inside the intermediate surface*. At the moment, the only example of that use
case is the text of the active tab in the state where the text is overflowing.

Both Servo and Gecko store the specified value of the image-orientation
property as a single-precision float, but Gecko does the conversion to radians
and the computation to identify which quarter-turn the angle is closest to
using doubles.
We add Angle::radians64 to perform the conversion to radians using doubles,
just as Gecko does, and then update image_orientation to perform the
computation the same exact way Gecko does in
nsStyleImageOrientation::CreateAsAngleAndFlip. This lets the previously failing
reftests pass.
We also update Gecko_SetImageOrientation to take an orientation directly
instead of an angle (otherwise we'd be doing the which-quarter-turn-is-closest
computation twice).
Finally this lets us re-enable the reftests for image-orientation previously
marked as fails-if(styloVsGecko||stylo).

Previously we just took the input angle mod 2π, which will leave negative input
angles as negative. By checking if the input mod 2π is negative and if so
adding 2π and then taking that mod 2π again we can ensure that we end up with a
an angle in the range [0, 2π].
We only do this if the result of the initial mod is negative because this adds
rounding error that is enough to mess up whether 135 is determined to be closer
to 90 or 180, for example.
We add a test for this as well.
Also fix property_database.js to account for this (we assert that -90deg should
compute to the same value as the initial value, but it should actually compute
to 270deg).

This change does the following:
* Introduce a new smart pointer called CounterStylePtr which either
holds an AnonymousCounterStyle strongly, or a named CounterStyle
managed by CounterStyleManager weakly, and use it to replace all
RefPtr<CounterStyle> around the codebase.
* Rename CounterStyleManager::mCacheTable to mStyles to reflect the
fact that it is used to manage all styles, not just for caching.
* Add a retired styles list which collect all named CounterStyle
evicted from mStyles, and post a PostRefreshObserver to destroy
objects in that list after next flush.
* Remove helper functions for counter style in nsStyleList and expose
mCounterStyle directly, to make code simpler with the new pointer.
Reason for adding a new smart pointer type rather than making their
AddRef/Release behave like BuiltinCounterStyle is that, it is possible
that after a flush, some stale style structs may still be alive. They
can contain pointer to destroyed CounterStyle objects. Although the
actual content may never be accessed anymore, RefPtr may still access
the object for refcounting during destruction.

This patch implement several things:
1. Implement a new constructor for nsStyleImageRequest to receive an existing
ImageValue from the caller.
2. Implement Gecko_ImageValue_Create to allow stylo to create a gecko::ImageValue
object.
3. Implement Gecko_SetXXXXImageValue to allow stylo to pass a created ImageValue
back to gecko.
