All its members are optional, so we can just use it as a plain struct
rather than Maybe<> all around, which simplifies the code and prevents
silly bugs like bug 1779592.
Mostly automatic via:
rg -l 'SVGImageContext' . | xargs sed -i 's/Maybe<SVGImageContext>/SVGImageContext/g'
With trivial build fixes.
Not intended to change behavior.

Add a dom/base/rust crate called just "dom" where we can share these.
Most of the changes are automatic:
s/mozilla::EventStates/mozilla::dom::ElementState/
s/EventStates/ElementState/
s/NS_EVENT_STATE_/ElementState::/
s/NS_DOCUMENT_STATE_/DocumentState::/
And so on. This requires a new cbindgen version to avoid ugly casts for
large shifts.

The scroll snap spec defines the concepts [1]. There are three type of scroll
operations. 1) intended end position, 2) intended direction and end position
and 3) intended direction.
Basically our existing ScrollUnits types correspond;
1) DEVICE_PIXELS, WHOLE => intended end position
2) PAGES => intended direction and end position
3) LINES => intended direction
There are two exceptions in the `intended direction and end position` case,
scrollBy() and fling gestures (on Linux). They were defined as scroll operations
with DEVICE_PIXELS unit, but the spec cleary says they are `intended direction
and end position` operations.
Note that we will also use this information for scroll-snap-stop property since
the properly will only have effects on both 2) and 3) cases.

I noticed we weren't doing this when looking at bug 1701910.
We remove support for auto style outlines in trees, which is unused
(checked that thunderbird and FF trees don't use outline: auto) and for
some mathml debugging code, which seems ok.

This patch doesn't change behavior; GetCrossDocParentFrameInProcess() is just a
wrapper for GetCrossDocParentFrame(), which is what we were calling before.
The "InProcess" version of this API (which we're migrating to in this patch) is
used to annotate GetCrossDocParentFrame() callsites that have been vetted as
being OK with the fact that this API returns null at the boundary of a
cross-origin iframe, if fission is enabled.
In this patch, the one call that I'm migrating is inside of XUL code
(specifically for the rendering of XUL trees); and we only expect to be
rendering XUL in a single process: Firefox's parent process. So this code
should be entirely OK with the fact that this API doesn't cross process
boundaries.

(Almost?) all other scrollbar performed scrolling goes through apz already (this effort was called "desktop_zooming_scrollbars").
This one mode was missed. It uses a repeating timer and setting the curpos attribute to trigger scrolling.
Unfortunately xul trees use this path as well, so we have to keep the old path around for them.
This makes one notable change in behaviour. Both before and after this patch single clicks on scrollbar buttons pass ENABLE_SNAP to the scroll from when they request scrolling (in nsScrollbarButtonFrame::HandleButtonPress). However for repeat scrolling when clicking and holding (which is handled by nsScrollbarFrame::MoveToNewPosition), before this patch the scrolling would not use ENABLE_SNAP. This is not super clear because MoveToNewPosition sets the curpos attributes, and then ScrollFrameHelper::CurPosAttributeChanged( would get called in response to that, and it would call ScrollToWithOrigin to the do scrolling, and it does not specify the snap mode, but the default is DISABLE_SNAP. This patch changes that so that we explicitly pass ENABLE_SNAP in MoveToNewPosition. It seems that this was likely overlooked (not hard to do when it's not clear like this) when adding snapping support. It makes sense to handle snapping the same way for single clicks and clicking and holding. If this turns out to be the wrong idea we can easily change it back.
Needs a test.

This makes the naming more consistent with other functions called
Insert and/or Update. Also, it removes the ambiguity whether
Put expects that an entry already exists or not, in particular because
it differed from nsTHashtable::PutEntry in that regard.

This allows supporting image-set(), etc, and simplifies the bullet frame
code significantly, too thanks to two changes:
* Instead of manually managing the image request, use the CSS image
loader, with the `REQUEST_REQUIRES_REFLOW` flag, to handle image
loads correctly. This didn't exist when this code was initially
implemented, but we can nicely use it now.
* Instead of re-implementing another WebRender command-builder thing,
we can just reuse the nsImageRenderer code.

This doesn't hold with fractional scale values. Right now GTK truncates
the scale factor, Windows rounds, and non-native theme rounds as well.
With this native theme will propagate correctly the floating point
values.
I tried to not change behavior meaningfully in any of the other themes,
mostly to avoid risk. GTK and Windows can be trivially tweaked to
support fractional scale factors properly if we wanted to, but seems
better to not do that as part of this patch.

When a tree row in the sidebar is selected, the background of that selected row
is styled with `-moz-appearance: -moz-mac-(active-)source-list-selection`.
We have two ways of rendering such selections:
1. With vibrancy, on 10.10+ if the sidebar itself uses vibrancy, and
2. With a solid fill, on 10.9 or if the sidebar itself does not use vibrancy.
In the Firefox main browser window, sidebar styling crosses document boundaries.
```
<hbox id="browser">
<vbox id="sidebar-box"> <-- this one has -moz-appearance: -moz-mac-source-list (or not)
<browser> (bookmarksSidebar.xhtml or historySidebar.xhtml)
<window>
<tree> <-- this contains the tree body frame which renders the tree contents,
including the selection backgrounds
```
We detect whether "the sidebar itself uses vibrancy" by walking up the frame tree
and looking for a frame with `-moz-appearance: -moz-mac-source-list`.
In the past, this lookup was inconsistent between nsTreeBodyFrame.cpp and theme rendering,
and it stopped at document boundaries. This patch makes the implementations more
consistent and allows it to cross document boundaries.
The old code only worked with the given DOM structure because `-moz-appearance: -moz-mac-source-list`
was repeated on the <tree> element. I'd like to remove that duplication.
The new code works correctly if `-moz-appearance: -moz-mac-source-list` is only set
on <vbox id="sidebar-box"> and not repeated on the tree.
