This doesn't change the layout behavior for page-break-before: always, since

There's a few subtle behavior changes here, which I'll try to break down in the
commit message.
The biggest one is the EditableDescendantCount stuff going away. This
was added in bug 1181130, to prevent clicking on the non-editable div from
selecting the editable div inside. This is problematic for multiple reasons:
* First, I don't think non-editable regions of an editable element should
be user-select: all.
* Second, it just doesn't work in Shadow DOM (the editable descendant count is
not kept up-to-date when not in the uncomposed doc), so nested
contenteditables behave differently inside vs. outside a Shadow Tree.
* Third, I think it's user hostile to just entirely disable selection if you
have a contenteditable descendant as a child of a user-select: all thing.
WebKit behaves like this patch in the following test-case (though not Blink):
https://crisal.io/tmp/user-select-all-contenteditable-descendant.html
Edge doesn't seem to support user-select: all at all (no pun intended).
But we don't allow to select anything at all which looks wrong.
* Fourth, it's not tested at all (which explains how we broke it in Shadow DOM
and not even notice...).
In any case I've verified that this doesn't regress the editor from that bug. If
this regresses anything we can fix it as outlined in the first bullet point
above, which should also make us more compatible with other UAs in that
test-case.
The other change is `all` not overriding everything else. So, something like:
<div style="-webkit-user-select: all">All <div style="-webkit-user-select: none">None</div></div>
Totally ignores the -webkit-user-select: none declaration in Firefox before this
change. This doesn't match any other UA nor the spec, and this patch aligns us
with WebKit / Blink.
This in turn makes us not need -moz-text anymore, whose only purpose was to
avoid this.
This also fixes a variety of bugs uncovered by the previous changes, like the
SetIgnoreUserModify(false) call in editor being completely useless, since
presShell->SetCaretEnabled ended in nsCaret::SetVisible, which overrode it.
This in turn uncovered even more bugs, from bugs in the caret painting code,
like not checking -moz-user-modify on the right frame if you're the last frame
of a line, to even funnier bits where before this patch you show the caret but
can't write at all...
In any case, the new setup I came up with is that when you're editing (the
selection is focused on an editable node) moving the caret forces it to end up
in an editable node, thus jumping over non-editable ones.
This has the nice effect of not completely disabling selection of
-moz-user-select: all elements that have editable descendants (which was a very
ad-hoc hack for bug 1181130, and somewhat broken per the above), and also
not needing the -moz-user-select: all for non-editable bits in contenteditable.css
at all.
This also fixes issues with br-skipping like not being able to insert content in
the following test-case:
<div contenteditable="true"><span contenteditable="false">xyz </span><br>editable</div>
If you start moving to the left from the second line, for example.
I think this yields way better behavior in all the relevant test-cases from bug
1181130 / bug 1109968 / bug 1132768, shouldn't cause any regression, and the
complexity is significantly reduced in some places.
There's still some other broken bits that this patch doesn't fix, but I'll file

Converted NS_STYLE_BORDER_STYLE_* consts to enum class. Updated corresponding values to enum class. reduced BCCornerInfo struct values to fit StyleBorderStyle values inside struct. Added defaults to switches that do not fully cover all instances of StyleBorderStyle.
This implements the mechanism reusing the animation machinery for now, so it
asserts in a few cases that this wouldn't handle correctly.
For shorthands that have colors and other bits we'd need a more sophisticated

This way we always serialize in the shortest form, and take less space.
This is useful because when serializing uncomputed values we'd like to compare
to the initial value to avoid serializing parts of a shorthand, but with the
existing implementation we would generate always a second keyword, which means
that we'll never match it.
This also matches Chrome and WebKit, incidentally, so I'm pretty confident the

multiple. In particular, now transitions don't get expired ever, until they
finish running of course.
That is not ok, given you can have something that the user can trigger to change
the style (hi, :hover, for example), and right now that triggers new
transitions, getting this into a really funny state.
I should give fixing this a shot, but it's non-trivial at all.
This cherry-picks part of servo/servo#20757.
This was done that way just because Servo didn't support the `all` property at
the time.
We should do it this way and optimize it if it's slow. Though I suspect that
most of stuff doesn't actually need to be inherited, my patch at bug 1498943
should make it much faster than what it would otherwise be.
This cherry-picks servo/servo#21946.
This implements the selector(<complex-selector>) syntax for @supports.
See https://github.com/w3c/csswg-drafts/issues/3207 for explainer and
discussion.
Probably would should wait for that to be sorted out to land this, or maybe we
should put it behind a pref to get the code landed and change our
implementation if the discussion there leads to a change.

This fixes the issue that we should no longer be looking for control characters.

Move MozLength and MaxLength into generics, and drop the manual implementation
of ToComputedValue.

In order to get the correct computed value of these keywords, we have to
make sure we store the correct computed values in sizing properties in
both inline axis and block axis.
-moz-max-content and -moz-min-content should behave as the property's
initial value in block axis. -moz-fit-content and -moz-available are not
supported in block axis, so we also treat them as initial values.

I plan to change servo to use all: inherit on its UA sheet.
I hope the patch below should make it good enough performance-wise. And also,
it's probably broken so I don't think it's worth supporting it specially.

This makes us not allocate useless style structs when you're doing something
like resetting an already-reset property, or inheriting an already-inherited
property.
Seemed simple enough that I think we should do it. In practice we don't even
should pay an extra branch because I expect the compiler to be smart enough and
merge it with the one in the mutate() call.
