SelectionChangeListener is an nsISelectionListener class. This is added only
to Selection for "normal" and added by nsFrameSelection::Init() after
AccessibleCaretEventHub. So, we can make Selection directly treat
SelectionChangeListener.

AccessibleCaretEventHub is an nsISelectionListener of Selection whose type is
"normal". This is added only when nsFrameSelection::Init() is called and
accessible caret is enabled. Additionally, nsFrameSelection::Init() is
always called immediately after creating nsFrameSelection.
Therefore, when AccessibleCaretEventHub is installed to Selection, this is
always second selection listener and won't be installed multiple times. So,
Selection can store pointer of AccessibleCaretEventHub directly only when
it's enabled and the Selection needs to notify it of selection change.
This patch makes Selection stores AccessibleCaretEventHub with RefPtr, then,
makes Selection::NotifySelectionListeners() call its OnSelectionChange()
immediately after AutoCopyListener.
Unfortunately, this patch includes making of MOZ_CAN_RUN_SCRIPT_BOUNDARY and
MOZ_CAN_RUN_SCRIPT a lot since some methods of AccessibleCaretEventHub are
marked as MOZ_CAN_RUN_SCRIPT and including AccessibleCaretEventHub.h into
Selection.h causes compile the compile errors.

When the frame updates for an animated image, it will trigger
nsImageBoxFrame::OnFrameUpdate to be called. We did not change this for
WebRender, and thus it was missing similar checks added to
nsImageFrame::InvalidateSelf as originally added in bug 1382985. This
caused us to ignore the frame update, and thus the animation never
appeared to progress.
nsAutoCopyListener is a singleton class but refcountable and a selection
listener. nsFrameSelection adds it to only normal Selection when it's on
macOS or it's enabled by the pref. Additionally, it's always first selection
listener since it's added immediately after Selection instance is created.
So, we can make it a static class, and normal Selection instance should have
a bool to decide whether it should notify nsAutoCopyListener of its changes.
Then, we can save the cost of grabbing it with local RefPtr and the virtual
call.
Additionally, this patch renames nsAutoCopyListener to mozilla::AutoCopyListener
and optimizes constructor of nsFrameSelection (using bool var cache to retrieve
the pref, avoid retrieving the pref on macOS).

This flag and function name are used for both basic shapes and path function,
so rename it. For now, we treat path() and other basic-shapes as the
different object (i.e. StyleSVGPath and StyleBasicShape), so I rename
these functions and mask flag.

Bug 1478178 regressed this case because bullet frame is the last frame
added to line layout, rather than the first, so when we try to apply
justification, we end up giving it the accumulated offset of the whole
line.
Bullet frame has to be added after other frames in the line have been
placed, because its presence may depend on whether the line is empty.
However, bullet frame is logically the first frame in a line and
appending it to the end is somewhat counter-intuitive.
Thus, this patch tries to fix the issue via prepending bullet frame in
line layout, so that the order of frames there can be more reliable.

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.
The layout implementation is in the later patch.

This crash happens because nsVideoFrame didn't know what to do with two
children in the UA Widget Shadow Root.
The two children are both videocontrols, with the first one being the lingering
DOM inserted by first constructor call that throws.
The subsequent appendChild of the same element caused the videocontrols
to be initialized again, since the previous run didn't return a widget
instance to UAWidgetsChild.
The fix here removes the throw statement added in
https://hg.mozilla.org/mozilla-central/rev/dca187f7c72c#l3.15 ,
allowing the constructor to complete.
Without this statement, we will rely on assertion in the test here
https://hg.mozilla.org/mozilla-central/rev/4ddca5eb06c2#l2.18
to fail on slower platforms to ensure the stylesheet is loaded synchronously.
An alternative fix would be to wrap up the contructor in a try catch block
from UAWidgetsChild and make sure the DOM is cleaned up when the constructor
throw. That however will hide the error thrown so I decided to remove the throw
statement instead.

Overflow properties have two semantics nowadays:
1. controlling whether the scrollbar should be shown;
2. controlling whether the content is scrollable.
However, with the scrollbar-width property being added, scrollability
and presence of scrollbar no longer binds together.
This change attempts to draw a boundary between value of overflow and
presence of scrollbar by making it clear that for ScrollReflowInput, we
only care about whether scrollbar should be shown. This should make it
easier to reason about further changes involving presence of scrollbar.

Gecko supports resizers of <img> elements and <table>, <td>, <th> elements and
has UI to remove existing table row or column in default. However, the other
browsers don't have such UI and web apps need to disable this feature with
calling both:
document.execCommand("enableObjectResizing", false, false);
document.execCommand("enableInlineTableEditing", false, false);
for avoiding conflicting with their own features to edit such elements.
Therefore, it doesn't make sense to keep enabling them in default only on
Gecko. If web apps want to keep using these features, they should call:
document.execCommand("enableObjectResizing", false, true);
document.execCommand("enableInlineTableEditing", false, true);
at initializing the editor.
And also this patch fixes bugs of
document.queryCommandState("enableObjectResizing") and
document.queryCommandState("enableInlineTableEditing"). They always return
false even after calling document.execCommand(..., false, true) since
nsSetDocumentStateCommand::GetCommandStateParams() sets bool value as
STATE_ATTRIBUTE. However, nsHTMLDocument::QueryCommandValue() which is the
caller referring STATE_ATTRIBUTE doesn't treat it as bool value. And also
those commands are related to state of document. Therefore, they should be
return as bool value of STATE_ALL instead. Then,
nsHTMLDocument::QueryCommandState() returns the state as expected. Note that
those commands are supported only by Gecko. So, we don't need to worry about
the compatibility.
Finally, this patch rewrites 2 existing tests to check basic behavior of
resizers and appearance of resizers.
Note that this patch does not add new tests to test inline table editor
since it's difficult to test the behavior with current API. Perhaps, we
should add an API to nsIHTMLEditor to retrieve each anonymous elements in
another bug since it requires to add wrapping API of SpecialPowers.

Correctness improvements:
* UTF errors are handled safely per spec instead of dangerously truncating
strings.
* There are fewer converter implementations.
Performance improvements:
* The old code did exact buffer length math, which meant doing UTF math twice
on each input string (once for length calculation and another time for
conversion). Exact length math is more complicated when handling errors
properly, which the old code didn't do. The new code does UTF math on the
string content only once (when converting) but risks allocating more than
once. There are heuristics in place to lower the probability of
reallocation in cases where the double math avoidance isn't enough of a
saving to absorb an allocation and memcpy.
* Previously, in UTF-16 <-> UTF-8 conversions, an ASCII prefix was optimized
but a single non-ASCII code point pessimized the rest of the string. The
new code tries to get back on the fast ASCII path.
* UTF-16 to Latin1 conversion guarantees less about handling of out-of-range
input to eliminate an operation from the inner loop on x86/x86_64.
* When assigning to a pre-existing string, the new code tries to reuse the
old buffer instead of first releasing the old buffer and then allocating a
new one.
* When reallocating from the new code, the memcpy covers only the data that
is part of the logical length of the old string instead of memcpying the
whole capacity. (For old callers old excess memcpy behavior is preserved
due to bogus callers. See bug 1472113.)
* UTF-8 strings in XPConnect that are in the Latin1 range are passed to
SpiderMonkey as Latin1.
New features:
* Conversion between UTF-8 and Latin1 is added in order to enable faster
future interop between Rust code (or otherwise UTF-8-using code) and text
node and SpiderMonkey code that uses Latin1.
