It's a rather useless interface:
* nsITextControlFrame is only implemented by nsTextControlFrame, so we
can just use that.
* nsIFormControlFrame had very few actual functionality, mostly
scattered around:
* SetFormProperty(select) was only useful for nsTextControlFrame.
* SetFormProperty(value) was only called on file controls.
* SetFocus() did mostly nothing, or things that can be done in
ElementStateChanged instead.
There are some do_QueryFrame calls that I replaced for better checks in
font inflation and nsIFrame, but I'll adjust to preserve behavior if you
insist (it just such a somewhat-random check).

We've tried to give `nsFileControlFrame` its own frame type "FileControl", but
it caused a crash and we revert its frame type back to "Block" in Bug 1825623.
That prevents the crash, but the frame tree is not correct since
`nsFileControlFrame` will have `nsBlockFrame` as its next-in-flow.
The proper way to fix the crash is disallowing the form control frame to split,
similar to what we did for `nsTextControlFrame` in
https://searchfox.org/mozilla-central/rev/fc76676f61ee37b4c5420649cad6677164a29405/layout/forms/nsTextControlFrame.cpp#670
This patch doesn't mean to promote frame type usage, but it might help the
broader frame type audit in the future once we switch frame type to QueryFrame
in bug 1555477.
Note this patch might have potential behavior changes since calling
`IsBlockFrame()` on `nsFileControlFrame` now returns `false` instead of `true`.
However, we have other concrete frames such as `nsMathMLmathBlockFrame`,
`nsSelectsAreaFrame`, etc. which have frame type "Block", and callers who need
to check `nsBlockFrame` and its subclasses are probably already using
`IsBlockFrameOrSubclass()`.

The following classes deriving from nsBlockFrame always set
NS_BLOCK_STATIC_BFC in their constructors or initializers:
- nsComboboxControlFrame
- nsFileControlFrame
- nsSelectsAreaFrame
- ColumnSetWrapperFrame
- nsMathMLmathBlockFrame
Do that in nsBlockFrame::Init instead. Behavior is unchanged.

After D198523, NS_BLOCK_FLOAT_MGR and NS_BLOCK_MARGIN_ROOT are always
set simultaneously when initiating a frame, so we can merge them into a
single NS_BLOCK_STATIC_BFC flag. The freed bit is used to define a new
NS_BLOCK_DYNAMIC_BFC flag that has the same effect and is now used for
frames with paint/layout containment so that in D197043 they can be
updated later without having to reconstruct the frame tree. Finally
NS_BLOCK_BFC_STATE_BITS is the bitwise union of these BFC flags.
The following changes are made and cause no behavior changes:
- Instead of testing whether NS_BLOCK_FLOAT_MGR or NS_BLOCK_MARGIN_ROOT
is set, or whether all of the bits from
NS_BLOCK_FORMATTING_CONTEXT_STATE_BITS are set, we test whether any
of the NS_BLOCK_BFC_STATE_BITS is set.
- Instead of adding NS_BLOCK_FORMATTING_CONTEXT_STATE_BITS when
constructing a frame, we add NS_BLOCK_STATIC_BFC. The exception is
for frame with paint/layout containment, for which we set
NS_BLOCK_DYNAMIC_BFC instead.

These flags are generally always set simultaneously via
NS_BLOCK_FORMATTING_CONTEXT_STATE_BITS. This commit changes the three
remaining places where only NS_BLOCK_FLOAT_MGR is set:
1. nsFileControlFrame, used by <input type="file">
2. nsComboboxControlFrame used by <select>
3. nsSelectsAreaFrame, used by <select multiple>
(1) and (2) create their own child frames that can't be styled by
authors. (3) wraps its children into a -moz-scrolled-content which
already prevents them from taking collapsing margins with their parent.
So it is safe to add NS_BLOCK_MARGIN_ROOT here.

This shouldn't change behavior, but it packs the two arguments to
DestroyFrom into a single thing, and makes nsIFrame::Destroy not so easy
to call without a previous context.
This is a prerequisite to pass aDestroyContext to various things that
right now just mint one, which can cause badness, see bug 1851787 and
related bugs.
It's also a bit nicer to add things there if we need to in the future.

That goes back to the introduction of display lists, but I don't think
it's needed, and in fact it causes correctness issues, since the file

here skips painting things like floats.

nsCSSFrameConstructor::CreateContinuingFrame creates a frame based on the
result of nsIFrame::Type(). The regressing bug changed the nsFileControlFrame
type from Block to its own FileControlType type, which meant that we stopped
creating nsBlockFrame continuations for it.
Fix it by restoring the previous behavior: changing the Type() back to return
Block, and using QueryFrame instead to check for the specific
nsFileControlFrame where we need to.
This is all rather messy, see bug 1555477 for related discussion.

Factor a MiddleCroppingBlockFrame that does the double reflow shenanigans.
That should both be faster and easier to reason about. The only thing we need

This is the main patch for the bug. It aims to change the grapheme cluster
break's `Next()` API by implementing SegmentIteratorUtf16 interface, and adapt
the callers. It shouldn't change the behavior.
While rewriting the caller, one caveat worth mentioning is the loop termination
condition. If the old code relies on `!AtEnd()` as the loop termination
condition, and it advances the iterator at the end of the loop, it meant
to *skip* its logic when the break position is at the end of the string. For
example, see the `mozTXTToHTMLConv::NumberOfMatches`.
This patch also hooks grapheme cluster break iterator into
Segmenter::TryCreate() interface.
Existing test coverage for the file changed:
- netwerk/test/unit/test_mozTXTToHTMLConv.js
- layout/reftests/forms/input/file/dynamic-max-width.html

In C++ code, `DataTransfer::GetTypes()` are used for checking whether the
`DataTransfer` instance has specific type `DataTransferItem` or not. Therefore,
it does not make sense to retrieve all item types nor compare some types
looking for with the retrieved item types.
This patch adds `DataTransfer::HasType()` and `DataTransfer::HasFile()` for
the current C++ users. They don't take `CallerType` since all C++ users use
`GetTypes()` as `CallertType::System`. And they just call a corresponding
method of `DataTransferItemList`.
Then, `DataTransferItemList` methods compares given type with every items
simply.
Note that this patch moves `DataTransfer::GetTypes()` to `DataTransferItemList`
too because new methods and `GetTypes()` should be maintained at every logic
changes.
The reason why there is no `DataTransfer::HasAnyOfTypes()` method is,
`DataTransfer.h` cannot include `DataTransferItemList.h` due to their
dependency but parameter pack requires inline methods.

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.
