Gijs for front-end bits, layout for the new CSS properties and the
removal of nsDeckFrame / nsStackLayout, Jamie and Morgan for the a11y
changes.
As discussed in the bug, the main tricky part here is handling a11y
correctly. For <deck>, that's trivial (just use `visibility: hidden` to
hide the panels visually, while removing the unselected panels from the
a11y tree).
For <tabpanels> however we need to do something special. We do want to
hide stuff visually, but we want to preserve the contents in the a11y
tree.
For that, the easiest fix is introducing a new privileged CSS property
(-moz-subtree-hidden-only-visually), which takes care of not painting
the frame, but marks stuff offscreen in the accessibility tree. This is
not intended to be a property used widely.
Other than that, the changes are relatively straight-forward, though
some of the accessible/mac changes I could get a sanity-check on.

Now that this doesn't involve an attribute lookup it's not worth it, and
this allows querying the flex of emulated flex items without hitting
assertions due to the lack of box metrics.

This makes it easier to get parity between legacy and regular flex
without having to either have tons of arbitrary attribute selectors in
the xul sheet, nor adding attribute lookup hacks to the html flexbox
layout.
Also, reimplement the remaining supported flex attribute-values (0 and 1)
purely in terms of CSS rules in xul.css (regardless of whether
emulate-moz-box-with-flex is enabled).
In practice these are pretty uncommon and the style attribute does the
trick in every case I've tried.
Add a debug-only assertion to ensure we preserve behavior for now.
Add a new test with another behavior difference between flexbox
emulation and old xul layout because the old reftest now passes. Use
replaced elements, which in modern flex are treated differently.

There's no reason we should need an scrollbar box to query the size of a
scrollbar. I plan to use this in the following patch to make the size of a
resizer not vary depending on whether the container has scrollbars or not,
which is what ultimately causes the reftest failure.

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.

There were some callers in nsRangeFrame that were already not-null-checking.
All platforms have a native theme and should we add new ones they could use
nsBasicNativeTheme.

Reuse the AddXULMinSize logic which already deals with all the widget stuff,
non-themed scrollbars, etc.
Remove some useless margin declarations and such in GeckoView scrollbars code
now that AddXULMinSize does look at the min-width/height properties.

This removes nsTreeColumns::RestoreNaturalOrder, which requires the ordinal attribute to function. It only has one consumer: toolkit/content/widgets/tree.js. The call is removed from that consumer in this patch. This will break column ordering in MozTree's, which is fixed by a later changeset in this stack.

The inclusions were removed with the following very crude script and the
resulting breakage was fixed up by hand. The manual fixups did either
revert the changes done by the script, replace a generic header with a more

This is consistent with the `order` property anyhow, and allows to simplify some
code.
Negatives are still not parsed, but rust uses a similar representation for all
CSS <integer> values and so should C++.

This simplifies dealing with frames that are pushed/pulled between
continuations during reflow, allows us to avoid the complexity of the
fix to 1459937, and hopefully fixes some of the regressions from bug
1308876.
This disables the changes from bug 1459937 by commenting out a single
line in ReparentFrameInternal in nsBlockFrame.cpp, but all the added
code will be removed in the following patch.

Really sorry for the size of the patch :(
Only intentional behavior change is in the uses of HasLengthAndPercentage(),
where it's easier to do the right thing. The checks that used to check for
(IsCalcUnit() && CalcHasPercentage()) are wrong since bug 957915.
