If selection range is not in **one** text node, `RemoveInlinePropertyInternal()`
collects target nodes with `SubtreeContentIterator`. It only collects topmost
nodes which are **entirely** contained in the range (it's enough because their
descendants will be handled by `RemoveStyleInside()` recursively).
The reasons why it uses `SubtreeContentIterator` rather than
`PreContentIterator` must be:
1. Performance reason.
2. Assuming there are no multiple text nodes.
3. Not expects that user removes text node styles come from parent block.
The reason 2 is wrong because when removing a style, all browsers don't
join text nodes which was in removing element with adjacent text nodes.
(I.e., we cannot change this behavior for compatibility.)
The reason 3 is of course wrong we're struggling with this scenario.
Therefore, `RemoveInlinePropertyInternal()` needs to collect partially
selected text nodes by itself (if there are). Then, we can merge the
single text node selected case with the `for` loop.

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.

Both method take a DOM point with `nsCOMPtr<nsINode>*` and `int32_t*`.
This makes each caller complicated. Instead, we should use stack only class
to return both `EditorDOMPoint` and `nsresult`. I name it `EditResult`.
Additionally, this fixes a bug of `HTMLeditor::SplitStyleAboveRange()`. That
is not tracking new selection start point while it splits elements at end
of given range. This is detected by the debug assertion in
`ToRawRangeBoundary()` (i.e., this fix is required to pass some tests).

Only for solving the order of `AutoEditInitRulesTrigger` destruction when
`HTMLEditor::Init()` calls `TextEditor::Init()`, `TextEditor` has unnecessary
counter and the initialization code is made harder to understand.
Therefore, this patch makes `TextEditor::Init()` and `HTMLEditor::Init()`
directly call `InitEditorContentAndSelection()` at appropriate time.
Additionally, `HTMLEditor::Init()` can call `EditorBase::Init()` instead of
`TextEditor::Init()` since `TextEditor::Init()` does nothing for `HTMLEditor`
actually.

`TextEditRules::DocumentIsEmpty()` is a wrapper of `TextEditor::IsEmpty()` so
that we can get rid of it simply.
`HTMLEditRules::DocumentIsEmpty()` needs to change. It's oddly checks only
`EditorBase::mPaddingBRElementForEmptyEditor` is `nullptr` or not. However,
the editor may be completely empty. And the result may be different from
`TextEditor::IsEmpty()` which is not overridden by `HTMLEditor`. For partially
solving this issue, this patch makes `HTMLEditor` overrides `IsEmpty()` and
optimizes `TextEditor::IsEmpty()`.
With this change, the caller of `HTMLEditRules::DocumentIsEmpty()` may behave
differently in the only caller, `HTMLEditor::SelectEntireDocument()`. And
unfortunately, its root called from `SelectAllCommand::DoCommand()`. However,
it does just collapse `Selection` into the root element (`<body>` or
`Document.documentElement`) if it returns `true`. Therefore, this change
must be safe since anyway `SelectionRefPtr()->SelectAllChildren()` with
the root element is exactly same as `SelectionRefPtr()->Collapse()` with
the empty root element if it's truly empty.

It does 4 different things so that it looks like a black-box from the
callers.
First, only `HTMLEditRules::WillDoAction()` refers `aCancel` out argument.
Therefore, it should check whether it's cancelled or not directly.
Next, `EnsureNoPaddingBRElementForEmptyEditor()` should be called by each
caller directly.
Then, the renaming part can be split to 2 methods. One is adjusting
caret position and the other preparing inline style for new content.
Unfortunately, this patch makes each caller messy. I think that for the
3rd job (i.e., adjusting caret position), each caller should retrieve the
adjusted caret position and use it directly instead of handling with
`Selection` in the future.
