Return a raw pointer instead of a strong reference to a ComputedStyle, and
handle the case of the style not being present by returning null rather than
requiring an extra function to check it and crashing if the precondition is not
met.
Also, name them so that it's clear they just return outdated styles and don't
make any extra effort.
This is just cleanup that makes the next patch easier / more obvious.

It was made pointless by the previous patch.
This replaces callers that had a frame type for another reason with the
frame type check that IsTableCell did, and callers that needed to call
Type() with an IsTableCellFrame call.

We want mHasColumnSpanSiblings to propagate to all the
continuations (both fixed ones or fluid ones) in nsFrame::Init() so that
we don't need to traverse all the way to FirstInFlow() for the bit in
nsBlockFrame::ComputeFinalBSize().
For the last ColumnSet or the last non-column-span wrapper, we'll need
to unset the bit for them manually after constructing them.

We naively remove and then recreate accessibles when their content's
frame is reconstructed. By delaying the removal until we are certain the
content does not have a new layout frame, we can cut down on redundant
recreations.
When reconstructed content is re-inserted we can check it and its
subtree for missing frames and prune those accessibles from the tree.

These frame state bits belong to the generic group, and there is
existing logic in nsFrame::Init() for carrying frame state bits. It's
better to consolidate them in one place.

After enabling column-span, ColumnSet becomes an anonymous child under
ColumnSetWrapperFrame. It doesn't need to handle border and padding,
containment, and non-auto block-size. ColumnSet's final block-size is
simply the union of ::-moz-column-content frames' rects.
However, we should extend ColumnSet's block-size to consume the
available block-size if the ColumnSetWrapper's block-size is constrained
so that the column rules are drawn to the block-end edge of the multicol
container.

In frame construction, a block can be split by column-spans into several
fragments and each of the fragments is chained together by non-fluid
continuations. Later in reflow, each fragment can create its own fluid
continuations due to reasons such as the constraint of its available
block-size.
The main idea of this patch is that we calculate the block's final
block-size by shrinkwrapping the children for every fragment except for
those fluid continuations after the final column-span. To do that, we
need to correctly tag each non-column-span-wrappers
nsIFrame::HasColumnSpanSiblings() except the last one.
We also need to modify nsSplittableFrame::ConsumedBSize() so that it
includes the block-size for both fluid and non-fluid continuations.

When privacy.spoof_english = 2, we should hide the user's
locale in content. So we use en-US default strings for HTML
form elements, such as a Submit button.
We also force GetLocalizedEllipsis() to always return the
ellipsis used by en-US.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

We don't need to treat a details frame as if it has multiple content
insertion points in order to reframe it. We can just put the logic into
WipeContainingBlock().

Bug 1507244 changes how NS_FRAME_HAS_MULTI_COLUMN_ANCESTOR is propagated
to the child, but I forget to add the bit for nested ColumnSetWrapper.
Currently, no other code depends on this bit being set on nested
ColumnSetWrapper, but Part 3 will. Without this patch,
testing/web-platform/tests/css/css-multicol/multicol-nested-margin-002.xht
will fail with Part 3.

For now I added everything to the same bucket, but I wrote this so it should be
easy to add more buckets as needed (either to mArenaSizes, or more specific ones
like the style system has). But this is probably enough for now.
