For consistency with the similar internal DOM API, `As*()` should just cast
the type without checking editor type. Instead, `GetAs*()` should do it.

`AlignStateAtSelection` class is instantiated outside of editor class so that
we shouldn't make each user guarantee that there is selection range
(fortunately, the putting off cost is really low).
And as far as I tested, Blink and WebKit does not throw exception when
`Document.qeuryCommand*("justify*")` is called without selection ranges.
So, this patch also prevents exception in this situation.

Some HTML editor command classes call `*AsAction()` methods multiple times.
That causes that user needs multiple undo/redo for a command and one command
causes multiple "input" events. For both compatibility with the other
browsers and making "beforeinput" cancelable, they should call `*AsAction()`
once. Instead, `HTMLEditor` should handle related element deletion.
This patch makes `HTMLEditor::RemoveInlinePropertyInternal()` remove multiple
elements if its caller allows, and `HTMLEditor::SetInlinePropertyAsAction()`
call `RemoveInlinePropertyInternal()` in some cases.
According to comm-central and BlueGriffon, we can make
`HTMLEditor::RemoveInlineProperty()` also removes the related methods
automatically because comm-central does same thing from script and BlueGriffon
does not use this. However, we cannot do that for
`HTMLEditor::SetInlineProperty()` because BlueGriffon may call it with any
HTML5 elements and does not expect removing elements in same block at that
time. If we needed to reduce the overhead of comm-central, we could change
only `RemoveInlineProperty()`, but it would make these APIs behavior
inconsistent.

For compatibility with Chrome, when removing inline style at block parent,
we should reset the style with creating `<span>` element whose `style`
attribute removes the style. We do this only in CSS mode, but we should do
it in HTML mode too.
This patch also makes `FontFaceStateCommand::SetState()` ignore `tt` value
if its root caller is `Document::ExecCommand()`. It was implemented for
composer to handle XUL command in bug 115922. Therefore, we should not do
this special handling on the web. If it were possible to separate this
change to another bug, it'd be nicer. But without this change, we'll have
a lot of regressions of `Document.execCommand("fontname")`. Therefore,
this is also fixed in this patch.
Note that this removes first `.ini` file selection because
the tests cannot be run without test number range parameter.
So, the sections are not used anymore.

`HTMLEditRules::WillMakeDefinitionList()` just calls
`HTMLEditRules::WillMakeList()` and `HTMLEditRules::WillMakeList()` can be
called as `HTMLEditRules::MakeOrChangeListAndListItemAsSubAction()` so that
we should merge them and make `HTMLEditor` call it directly.
This patch also removes default action part of
`HTMLEditor::MakeOrChangeListAsAction()` because it runs only when
`HTMLEditRules::WillDoAction()` does not return canceled nor error but not
handled, however, it's won't occur since `HTMLEditRules::WillMakeList()`
always sets `aHandled` to `true` when it returns `NS_OK`.

`Document::ExecCommand()` knows subject principal. This patch makes it tell
`EditorCommand::DoCommand()` and `EditorCommand::DoCommandParam()`. Then,
makes they tell each editor public methods which may cause dispatching
`beforeinput` event once we implement it. Finally, each editor public
method sets it to the constructor of `EditorBase::AutoEditActionDataSetter`.
This means that when editor tries to dispatch `beforeinput` event, editor
can check whether it's called by JS or not from everywhere.

`cmd_align` is always with `nsCommandParams` when it's executed. However,
when somebody checks whether the command is enabled or not, or retrieves the
state, `GetInternalCommand()` is called without `nsCommandParams`. Therefore,
even when `nsCommandParmas` is nullptr for `cmd_align`, `GetInternalCommand()`
shouldn't warn it.
Additionally, internal command supports to set `align` to empty string.
Therefore, `GetInternalCommand()` also needs to support it.
This patch adds `Command::FormatJustify` for the former case and
`Command::FormatJustifyNone` for the latter case.
Note that this does not affect to actual behavior since `AlignCommand`
does not refer the result of `GetInternalCommand()`.

Most `EditorCommand` classes don't require additional params for executing
a command. All of them just calls their `DoCommand()` or returns same result.
So, we can create new virtual method,
`EditorCommand::DoCommandParam(Command aCommand, TextEditor& aTextEditor)`,
which just delegates to `DoCommand()`.
This patch adds some undeclared commands but which are handled by
`EditorCommand` subclasses, and changes `CommandInt` type from `int8_t` to
`uint8_t` since the count of `Command` items becomes over 128.

Currently, this bug does not occur actually because nobody has not accessed
these command classes directly and they are registered only in command table
for HTML editor. However, once rewriting `nsHTMLDocument::ExecCommand()` with
these classes, its `IsCommandEnabled()` should return false if given editor
is `TextEditor`. The reason why we need this fix is, when we make
`ExecCommand()` call `IsCommandEnabled()` and it returns `true`, `ExecCommand()`
needs to call `DoCommand()`. Then, it throws exception if given editor is not
an `HTMLEditor` but the command class is only for `HTMLEditor`.
This patch adds new WPT for testing whether `document.execCommand()` works
with `<input>` and `<textarea>`. The behavior has not been standardized, but
Chromium handles some commands even in it. So, I write the expectations from
the point of view of web developers. (Chrome fails in "cut", "copy" and
"removeformat" cases.)

`CanCut()`, `CanCopy()` and `CanPaste()` return error only when the editor has
already been destroyed or not been initialized yet, or when failed to access
clipboard when the document is not HTML/XHTML.
`CanDelete()` returns error only when the editor has already been destroyed or
not been initialized yet.
So, these error result won't be exposed to the web in most cases and such
exception shouldn't stop any content script because Chrome basically does not
throw exception in such situation as far as I know.
Therefore, there should be overloads of them to return `bool` result directly
for making their callers simpler.

Some "HTML editor commands" are stateful due to storing tag name to handle it
with specific command. However, we can make it stateless with retrieving
tag name from command name once per command only when it's necessary. The
runtime cost must be really cheap since we can map it with hash table.
This patch makes them stateless and singleton classes. So, we can save
footprint and allocation runtime cost with this change.
