As I said over bug 1549593, the eventual goal is to use ArcSlice in all
inherited properties. But this seemed like a good first candidate that doesn't
require me to move around a lot more code, since we were already using cbindgen
for the path commands.

This enables destructors for tagged unions in cbindgen, implemented in:
* https://github.com/eqrion/cbindgen/pull/333
Which allow us to properly generate a destructor for the cbindgen-generated
StyleBasicShape (which now contains an OwnedSlice).
For now, we still use the glue code to go from Box<BasicShape> to
UniquePtr<BasicShape>. But that will change in the future when we generate even
more stuff and remove all the glue.
I could add support for copy-constructor generation to cbindgen for tagged
enums, but I'm not sure if it'll end up being needed, and copy-constructing
unions in C++ is always very tricky.

It's not worth dying on this hill. Both Blink and WebKit pass the tests.
(Well, WebKit actually fails one of the latest ones I wrote, cssRules and rules
are not the same JS object, WebKit returns a new rule list. I'll file)

This is in preparation to disable (but not remove) support for these customizations
by default. We want to avoid scanning for these files on start-up, but also don't want
to make our users jump through a pref-flipping hoop to get their customizations back.
So we'll detect those files and flip the pref for this release. For the next release,
we'll not load those files unless the pref is flipped.

Before this change, only elements inside the shadow root tree were scanned for the
draggable=true attribute. We now check the flattened tree instead so an element
inside a shadow root can start a drag for an element containing the shadow root.

The patch in bug 1507744 was not sufficient by itself, as the line-breaker could still accumulate a single "current word" across a text-run boundary, and then a single word-break value would be applied to it. We need to flush the line-breaker when word-break changes, so that each part of the word will have break opportunities set according to the appropriate value.

Add multicol-width-004.html and multicol-width-005.html to test "width:
min-content" and "width: max-content" with column-span:all children.
There's no size containment in these tests.
Note it may be worth to reuse nsBlockFrame's mCachedMinISize and
mCachedPrefISize to cache intrinsic size for ColumnSetWrapperFrame, but
this can be done separately.

If column-span is enabled, nsColumnSetFrame becomes an inner frame under
ColumnSetWrapperFrame, and that outer frame is then where we should be
handling size containment.
This patch doesn't change the logic but make the logic easier to
simplify once we start eliminating column-span pref.

ColumnSetFrame always tries to reflow column content regardless of it's

In order to show all popups on Wayland we need to set popup parent runtime for popups which don't have
fixed parent. For instance popup menus (fired after right button mouse click) can be issued on top of another popup
and we need to follow that connection on Wayland.
We track all open (active) popups to:
- close all visible tooltip windows when we're going to open another tooltip
- close concurrent popup on the same level when a new one is about to open
- get latest active popup as a parent for a new tooltip windows
- get latest active popup as a parent for a new popup menu without fixed parent

The test itself is reasonable, except that it reads scroll positions
from the main thread. With APZ enabled we need to flush any pending APZ
repaints before reading these scroll positions. So changing the
waitForAllPaints to the APZ-flushing variant makes that happen, and the
test passes.

Unfortunately, `EventChainVisitor` does not grab the `nsPresContext` with
`RefPtr` by itself. Therefore, there is no guarantee of the lifetime without
checking the origin when its subclasses are instantiated. This patch changes
it and subclasses to `MOZ_STACK_CLASS` since only `EventDispatcher::Dispatch()`
creates them in the stack with given `nsPresContext`. Additionally, it's
already been marked as MOZ_CAN_RUN_SCRIPT_BOUNDARY`. Therefore, the
`nsPresContext` instance has already been guaranteed its lifetime by the
caller. For making this fact stronger, this patch marks their constructors
as `MOZ_CAN_RUN_SCRIPT`. Therefore, nobody can create those instances without
guaranteeing the lifetime of `nsPresContext` and `dom::Event`. Note that
it may look like that `mPresContext` of `EventChainPostVisitor` is not
guaranteed. However, `EventChainPreVisitor` which gives `nsPresContext` to it
is also a stack only class. So, it won't be deleted before
`EventChainPostVisitor` instance.
