When CSS rules change, we usually do this implicitly from FlushUserFontSet & co.
However there's a code path that dirties the stylist but not the CSS rules, and
that's when the compat mode changes and we're an SVG document.
I don't think that can get hit (easily, at least?), but it's pretty easy to do
so and I think this is cleaner too.
This fixes that case so the stylist can't assert in that case either, and so
that we still rebuild the cascade data so that the hash maps use the right keys
for a given quirks-mode.

Mostly testing that they work, and that they record what we expect them to
record, that is, the actual property that was parsed, and not the properties
that it'd resolve or expand to.
That may be another tricky part for CSSOM, I think style setters would fail an

For now, |clip-path: path()| is chrome-only, and not for shape-outside,
so we only implement the parser for clip-path. Besides, I didn't put
path() in BasicShape because path() doesn't use the reference box to
resolve the percentage or keywords (i.e. SVG path only accept floating
point or integer number as the css pixel value). Therefore, I add it into
ShapeSource, instead of BasicShape.

Note: rename mCombinedTransform as mIndividualTransform, which only

Define OffsetPath & SVGPathData on the servo-side, and StyleMotion &
StyleSVGPath on the gecko-side. We parse the SVG Path string into a
vector of PathCommand. To build the gfx::Path, we will convert it into
gfx::Path later in a different patch.
The basic flow is:
* Parse SVG Path String into SVGPathData (in Rust).
* Use cbindgen to make sure the layout of PathCommand and StylePathCommand,
and then set the Box[PathCommand] into nsTArray<StylePathCommand>.
* Try to convert nsTArray<StylePathCommand> into gfx::Path. (This part
will be implemented in a different patch.)
Finally, we use the gfx::Path to create a motion path transform.

We share the inner object across sheets from the same URL, so what happens here
is that, once the sheet parses and loads, we call SetEnabled() on the first
sheet, which sets the inner bit, then calls ApplicableStateChanged.
That set actually turned the second sheet complete, so when inserting the sheet,
we think that the second sheet is already enabled, and thus in the author data,
and try to insert before it. Of course there's nothing there, so we panic.
We rely on calling SetEnabled() on all the sheets already to insert them in the
styleset / author data, so this makes it clearer and fixes the bug by moving the
state to each individual sheet.

This fixes a rather subtle bug. What the underlying code here is trying
to do is remove nsChangeHint_UpdateContainingBlock when some properties
that influence whether a frame is a containing block for absolutely
positioned or fixed positioned elements have changed, but the final
calculation of being a containing block has not changed. However, the
old code was using a function that tested whether the style could
*possibly* lead to a frame being a containing block. Some of the
properties (like the transform properties) that lead to being a
containing block, for example, don't apply to non-replaced inlines.
Some, however, do (such as 'filter'). So if there's a dynamic change
adding or removing a filter, on an inline that also has an *ignored*
transform property (like 'transform' or 'perspective') set, then the
code prior to this patch causes us to remove the UpdateContainingBlock
hint.
This patch fixes things by testing whether being a containing block
could have changed for *any* type of frame, by separately testing the
changes.
The added tests fail without the patch and pass with the patch, viewed
in isolation. However, without the previous patch, test 003 passes.
Test 003 also fails in Chrome (but 001 and 002 pass).

We only have this so that ::-moz-placeholder keeps serializing as

Edge aliases ::-webkit-input-placeholder to ::-ms-input-placeholder at parse
time as well, as can be seen in:
```
let s = document.createElement('style');
s.innerHTML = `input::-webkit-input-placeholder { color: red };`;
document.body.appendChild(s);
document.body.innerHTML = s.sheet.cssRules[0].cssText;

Everything that goes in a PLDHashtable (and its derivatives, like
nsTHashtable) needs to inherit from PLDHashEntryHdr. But through a lack
of enforcement, copy constructors for these derived classes didn't
explicitly invoke the copy constructor for PLDHashEntryHdr (and the
compiler didn't invoke the copy constructor for us). Instead,
PLDHashTable explicitly copied around the bits that the copy constructor
would have.
The current setup has two problems:
1) Derived classes should be using move construction, not copy
construction, since anything that's shuffling hash table keys/entries
around will be using move construction.
2) Derived classes should take responsibility for transferring bits of
superclass state around, and not rely on something else to handle
that.
The second point is not a huge problem for PLDHashTable (PLDHashTable
only has to copy PLDHashEntryHdr's bits in a single place), but future
hash table implementations that might move entries around more
aggressively would have to insert compensation code all over the place.
Additionally, if moving entries is implemented via memcpy (which is
quite common), PLDHashTable copying around bits *again* is inefficient.
Let's fix all these problems in one go, by:
1) Explicitly declaring the set of constructors that PLDHashEntryHdr
implements (and does not implement). In particular, the copy
constructor is deleted, so any derived classes that attempt to make
themselves copyable will be detected at compile time: the compiler
will complain that the superclass type is not copyable.
This change on its own will result in many compiler errors, so...
2) Change any derived classes to implement move constructors instead
of copy constructors. Note that some of these move constructors are,
strictly speaking, unnecessary, since the relevant classes are moved
via memcpy in nsTHashtable and its derivatives.
And general Element logging. We now print all the attributes for comparison.
If this turns out to be too verbose we can change it to diff them or something.

That said, we use this feature extensively internally (e.g. in DevTools etc.) so
we enable this feature for system callers.

I initially tried to avoid this, but decided it was necessary given the number
of times I had to repeat the same pattern of casting a variable to void*, and
then casting it back in a part of code far distant from the original type.
This changes our preference callback registration functions to match the type
of the callback's closure argument to the actual type of the closure pointer
passed, and then casting it to the type of our generic callback function. This
ensures that the callback function always gets an argument of the type it's
actually expecting without adding any additional runtime memory or
QueryInterface overhead for tracking it.

nsComputedDOMStyle is currently one of the biggest sources of pref callback
memory overhead. It currently registers about 5KB of callbacks per process. A
lot of that has to do with it registering multiple callbacks for the same
preference. But even with that problem fixed, we can do better by registering
a single callback for all observed preferences.
This patch does that, but also adds the optimization of deduplicating the list
of observed preferences to avoid wasted cycles needlessly matching against
many identical strings.

Many tests set the dom.animations-api.core.enabled pref to true when all they
really require are the features covered by the dom.element-animate.core.enabled
pref. Now that we have removed that pref and permanently enabled that
functionality we can drop the annotations from such tests.

Most preference callbacks use literal strings for their domain filters, which
means that there's no need to make copies of them at all. Currently, however,
every preference observer node makes a separate heap-allocated copy of its
domain string.
This patch switches the domain string storage to nsCString instances, which
dramatically reduces the amount of unnecessary copies, at the expense of
making the callback nodes slightly larger.

This changes the order of properties returned from gCS. The old order
doesn't make much sense, and other browsers don't agree on an identical
order either, so it should be trivial to change it. Also the spec isn't
super clear / useful in this case.
Several -moz-prefixed properties are excluded from the list due to their
being internal. I suspect they are never accessible anyway, so probably
nothing gets changed by this.

The idea with this patch is that style code will first call
InlineStyleDeclarationWillChange before style declaration has changed, and SetInlineStyleDeclaration once it has changed.
In order to be able to report old attribute value, InlineStyleDeclarationWillChange reads the value and also calls AttributeWillChange (so that DOMMutationObserser can grab the old value). Later SetInlineStyleDeclaration passes the old value to
SetAttrAndNotify so that mutation events and attributeChanged callbacks are handled correctly.
Because of performance, declaration can't be cloned for reading the old value. And that is why the recently-added callback is used to detect when declaration is about to change (bug 1466963 and followup bug 1468665).
To keep the expected existing behavior, even if declaration isn't changed, but just a new declaration was created (since there wasn't any), we need to still run all these
willchange/set calls. That is when the code has 'if (created)' checks.
Since there are several declaration implementation and only nsDOMCSSAttributeDeclaration needs the about-to-change callback, GetPropertyChangeClosure is the one to initialize the callback closure, and the struct which is then passes as data to the closure.
Apparently we lost mutation event testing on style attribute when the pref was added, so test_style_attr_listener.html is modified to test both pref values.
