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.

Note that this is an imperfect implementation, in that it doesn't exactly
match the sizing behavior of a truly empty `<select>` element. I've filed
followup bug 1562057 on that. However, the behavior that's implemented
here *does* successfully make us ignore a `<select>`'s contents for sizing
purposes, and it's much better than what we do currently (which is pretty
broken via inheriting a partial `contain:size` implementation from our
parent class, nsBlockFrame).

I think this is a good change regardless of other discussion in bug 1552587. If
we decide to move `mColor` to the top-level of the struct that can be done
separately.

This should be an idempotent patch. The way to come up with this patch has been:
* Run the first script attached to the bug and pipe it to xclip, then paste it
in color.rs
* Add the relevant #[derive] annotations and remove the color.mako.rs
definition.
* Reorder the values to match the ColorID definition, on which some widget
prefs and caching stuff relies on.
* Manually port some documentation from nsLookAndFeel.h
* Run `rg 'eColorID_' | cut -d : -f 1 | sort | uniq >files`
* Run the second script attached to the bug.
* Manually fix usage of `LAST_COLOR` (adding the `End` variant), and adding
casts to integer as needed.
* Add an static assert so that people remember to update the prefs, rather than
a comment on the definition :)

We previously (in bug 1491235) adjusted some utility code to make
layout-contained frames behave as if they have no baseline.
But that's not sufficient. To make frames fully report lack-of-a-baseline,
we now do the following for layout-contained frames, as of this patch:
(a) We now leave the ReflowOutput outparam's BlockStartAscent member at its
default value (which is what we do for frames without a baseline like
e.g. nsCheckboxRadioFrame and nsHTMLCanvasFrame). And if the parent cares
about the baseline, it'll then ask directly, using a baseline getter.
(b) We now return 'false' in more implementations of bool-returning
baseline-getter-methods (where 'false' indicates 'no baseline').
(c) We now return the margin-box-bottom edge, in the nscoord-returning
'GetLogicalBaseline()' getter method. (We typically do this by deferring
to the inherited method, which ultimately comes from nsFrame's
implementation). It's appropriate to use the margin-box-bottom edge when
there's no baseline, per the definition of 'vertical-align: baseline',

D29542 fixed the bogus checks that was making nested pseudo-elements match
author rules. This adds tests and ends up being just a cleanup, though as it

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.

We always include the combinator for pseudo-elements now (not including it was
just an optimization) in order to not match when nested pseudo-elements are
involved.
We could add a more generic check in `matches_simple_selector` like:
```
if element.is_pseudo_element() {
match *selector {
Component::PseudoElement(..) |
Component::NonTSPseudoClass(..) => {},
_ => return false,
}
}
```
But even that wouldn't be enough to make selectors like `:hover::marker` not
match on the `::before::marker` pseudo-element, plus that code is really hot.
So for now do the check on the `next_element_for_combinator` function. It's a
bit hacky but it's the best I could came up with...
While at it, simplify some checks to use is_pseudo_element() instead of
implemented_pseudo_element() directly.
Only the Rust patch as-is would make markers for ::before and ::after on list
items not show up, so we also need to switch ::marker to use ProbeMarkerStyle()
rather than ProbePseudoElementStyle(), since the marker should exist even if it
matches no rules.

They do nothing, if they get parsed, they end up doing the same as text-align:
start, which is the same that we'd get out of GetLogicalAlign if the attribute
wasn't parsed in the first place.
We don't use this attribute for anything else like attribute mapping, so this
should be an idempotent patch.

Per the discussion in:

They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in
the type name, and turn them into CamelCase.

This patch moves some `enum` in `nsIPresShell` which are in public scope into

This patch creates new header, `mozilla/PresShellForwards.h`. It should have
all forward declarations of global class/struct in `nsIPresShell.h` and
`mozilla/PresShell.h`.
Additionally, this moves all `enum`s and `constant`s in them into the new file
with changing them to `enum class`es.
This will make other headers which require only specific types in the header
files not include them.
