Computed color values will not be in the correct format, closer to the
one specified by the author. This also means that colors accross the
code are stored now as AbsoluteColor or StyleAbsoluteColor. This allows
color space/gamut information to be available for use.
Some animation related test failures had to be changed, because colors
now has greater precision. Animated a color now causes a lot more
animation updates, which was not initially expected. See the bug for
discussion.

This patch creates a base class of `EditorInlineStyle`, the name is
`EditorElementStyle`. It requires only attribute of HTML. However, it's
obviously different from `EditorInlineStyle`'s rule which is `mHTMLProperty`
cannot be `nullptr`. Therefore, the methods which can treat only
`EditorInlineStyle` do not want the data only whose attribute is not `nullptr`.
For solving this issue at build time, this approach is better than renaming
`EditorInlineStyle` and make it have the new mode.

Any callers do not refer "ignored", "handled" and "cancel" state without
checking whether the method returns error or not. Therefore, error state
can be (and should be) managed by `mozilla::Result`'s error state.
Perhaps, it should store a caret position later because deletion handlers
of `HTMLEditor` use it, but update `Selection` immediately.

Similar to the previous patch, this changes a lot of lines. However, I think
that it's not so hard to investigate regression point in this patch because

The following patches touch the logic to restore selection after handling
commands. However, it seems that they are not tested because I found some
regressions by manual testing, but didn't cause orange on tryserver.
`outdent-preserving-selection.tentative.html` causes a crash due to the
`MOZ_ASSERTION` in `HTMLEditor::HandleOutdentAtSelectionInternal`. It means
that I misunderstand the logic and had put the assertion. I should fix it
later with reading the complicated code again. For now, I just change it
to `NS_WARNING_ASSERTION` instead.
And also `test_cmd_absPos.html` is the first test to check toggling `position`
between `static` and `absolute`. Therefore, it detects wrong `MOZ_ASSERT`s
which test whether `EditActionData` or `TopLevelEditSubActionData` is created
or not **before** they create them by themselves. So, this patch removes the
wrong assertions.

It's always work with `Selection` ranges. Then, it should be treated within
`AutoRangeArray` which can be initialized with `Selection` ranges automatically.
Then, we can making `HTMLEditor` simpler.
Note tha this tries to make it get editing host when the corresponding
public method is called (after dispatched `beforeinput` event if handling a
users' operation). However, as commented in
`HTMLEditor::SetParagraphFormatAsAction`, it breaks a tricky crash test.
Therefore, only the format block path computes it after the preparation.

It's currently computes the corresponding editing host from the focus node of
`Selection` with climbing up the DOM tree. So, it does not just return a stored
element. Therefore, some callers use it multiple times. For avoiding it, we
should rename it to explain that it computes the editing host.
Note that I think that we should make it takes a node to compute editing host
without `Selection` for solving the case of no selection ranges. Therefore,
I don't like to include more information into the name.

It returns the anonymous `<div>` element if the instance is a `TextEditor`, and
compute editing host otherwise. So it's unclear what it returns. Additionally,
all users except `EditorBase::CreateTransactionForCollapsedRange` are the
methods of `HTMLEditor`. Therefore, we should remove it and unwrap the code
which it's done.

When the grabber to move absolutely positioned element is disabled,
`HTMLEditor::HideGrabberInternal()` is called to delete it. However,
it does not reset dragging state. Therefore, `mousemove` event listener
will try to handle drag even after the grabber is removed.
This patch makes `HideGrabberInternal()` reset the dragging state to
make the event listener stop handling the drag action.
However, I hit a buggy assertion in `EventStateManager`. It tries to
set active state to parent of the grabber (in this case, absolutely positioned
element). However, editable element in `contenteditable` cannot have
active state. Therefore, `leaf` becomes `nullptr`, but `newleaf` is the
absolutely positioned element. Therefore, this patch adds this condition
into the `MOZ_ASSERT`.

Although we use CSS property for Inline table editing UI, we use edit
transaction for it unfortunately. When hiding this UI, since removing
element doesn't use edit transaction, transaction will be canceled before
showing this UI.
It is unnecessary to use edit transaction for UI, so we shouldn't use it.

The root cause of this bug is a bug of async `ScrollSelectionIntoView` that
is what it won't be canceled even if web app changes scroll position with
any API. Fixing it is really risky and this bug affects an existing website.
Therefore, this patch makes the constructors of `AutoPlaceholderBatch` take
whether do or do not `ScrollSelectionIntoView` when it's destructed. And
makes `HTMLEditor::SetInlinePropertyAsAction()` not request
`ScrollSelectionIntoView` for taking back the traditional behavior.
Note that this patch does not make it an optional argument because it's hard to
guess that it'll run `ScrollSelectionIntoView` automatically.

`AutoEditActionDataSetter` is created in the stack when editor's public method
is called and that guarantees lifetime of global objects in editor such as
editor itself, selection controller, etc.
The dispatcher of `beforeinput` event returns `NS_ERROR_EDITOR_ACTION_CANCELED`
if an event is actually dispatched but canceled. The reason why it's an error
is, editor code must stop handling anything when any methods return error.
So, returning an error code is reasonable in editor module. But when it's
filtered by `EditorBase::ToGenericNSResult()` at return statement of public
methods, it's converted to `NS_SUCCESS_DOM_NO_OPERATION`. This avoids throwing
new exception, but editor class users in C++ can distinguish whether each edit
action is canceled or handled. The reason why we should not throw new
exception from XPCOM API is, without taking care of each caller may break some
our UI (especially for avoiding to break comm-central). Therefore, this patch
does not make XPCOM methods return error code when `beforeinput` event is
canceled.
In most cases, immediately after creating `AutoEditActionDataSetter` is good
timing to dispatch `beforeinput` event since editor has not touched the DOM
yet. If `beforeinput` requires `data` or `dataTransfer`, methods need to
dispatch `beforeinput` event after that. Alhtough this is not a good thing
from point of view of consistency of the code. However, I have no better
idea.
Note 1: Our implementation does NOT conform to the spec about event order
between `keypress` and `beforeinput` (dispatching `beforeinput` event after
`keypress` event). However, we follow all other browsers' behavior so that it
must be safe and the spec should be updated for backward compatibility.

Note 2: Our implementation does NOT conform to the spec about event order
between `compositionupdate` and `beforeinput`. Our behavior is same as
Safari, but different from Chrome. This might cause web-compat issues.
However, our behavior does make sense from point of view of consistency of
event spec. Additionally, at both `compositionupdate` and `beforeinput`,
composition string in editor has not been modified yet. Therefore, this
may not cause web-compat issues (and I hope so).
