The other `Move*()` are not move nodes without transactions. For making
developers to distinguish the difference, this patch appends `WithTransaction`
postfix like other methods which modify DOM tree with transactions.

Even though the method returns only in specific cases, but the result affects
only one caller, `HTMLEditor::GetNextSelectedTableCellElement()`. Therefore,
we can create new generic utility method,
`HTMLEditUtils::GetTableCellElementIfOnlyOneSelected()` and get rid of
`HTMLEditor::GetCellFromRange()`.
Note that the warnings in `HTMLEditor::GetCellFromRange()` is just noise for
any callers. So, this gets rid of the useless spam warnings.

Currently, `EditorBase::ExtendSelectionForDelete()` depends on some
`nsISelectionController` methods to compute extended range for deletion
from collapsed selection. They are implemented by
`nsFrameSelection::MoveCaret()` and `nsFrameSelection::TakeFocus()`.
Ideally, we should split these methods for computation part and performing
part. However, they change selection with updating other selection state,
for example, table selection state and bidi information. Therefore, it's
impossible to split them with simple code. However, I need to change
`EditorBase::ExtendSelectionForDelete()` just return extended range.
Therefore, this patch creates `nsFrameSelection::PeekOffsetForCaretMove()`
which has the main path in `MoveCaret()` for the `EditorBase` method.
Then, `MoveCaret()` and new `nsFrameSelection::CreateRangeExtendedToSomewhere()`
share the computation code of expanding normal selection.
Finally, this patch wraps `nsFrameSelection::CreateRangeExtendedToSomewhere()`
with new public inline methods for `EditorBase`.
The following patch will remove no-user methods of `nsISelectionController`.

They are used only by `HTMLEditor` so that we should hide them from
`TextEditor` for making it clearer that they are not used by `TextEditor`.
Note that there are 2 `DeleteNodeWithTransaction()` in `HTMLEditor` class.
One is `EditorBase`'s method and the other is `HTMLEditor`'s method.
`HTMLEditor`'s one is check whether the removing node is editable or not,
but in some cases, we need to move non-editable nodes. Therefore, this
patch makes `ReplaceContainerWithTransaction()` call `EditorBase`'s one
for keeping current behavior.

The out params mean the last collapsed selection range's result (although,
the meaning is odd and offset and length are not overwritten when there is
another collapsed range and it causes `DeleteNodeTransaction`). Additionally,
when and only when `DeleteNodeTransaction` and `DeleteTextTransaction` are
added to the `EditAggregationTransaction` created by
`CreateTransactionForSelection()`. Therefore, same result can be looked for
from its only caller, `DeleteSelectionWithTransaction()`.
Note that this makes the method slower if there are too many selection ranges,
but such case must be rare because:
1. We can assume that users rarely use multiple selection ranges for removing
multiple ranges of content except table.
2. Multiple selection is supported only by Gecko. Therefore, web apps must
not use multiple selection for this purpose.
So, it must be okay to use this slower approach for making the methods simpler.
If it'd become damage to some benchmarks, let's create faster access to get
transaction type.

`HTMLEditor::DeleteSelectionWithTransaction()` calls `EditorBase`'s overridden
method and handles `nsIEditor::eStrip` case. Therefore, we can rename it with
stop calling the `EditorBase::DeleteSelectionWithTransaction()`, and make it
called by `EditorBase::DeleteSelectionWithTransaction()` only when it's
necessary.
Additionally, we can make all internal method callers of editor classes always
set `nsIEditor::eNoStrip` if the instance is `TextEditor`. This must make
the code easier to understand.

The parameter is used only by `EditorBase::CreateTxnForDeleteRange()` to
extend collapsed range, but it accepts only `nsIEditor::eNext` and
`nsIEditor::ePrevious`. Therefore, using `nsIEditor::EDirection` does not
make sense. Instead, they should use new `enum class`,

Currently, all input (including user pastes) to an input field is truncated to
`maxlength`. This diff disables truncation for user pastes.
When (1) `GetEditAction` is `ePaste`, `ePasteAsQuotation`, `eDrop`, or
`eReplaceText` (ie we are dealing with a paste) and (2) `GetEditActionPrincipal`
is `nullptr` (ie we are dealing with a user edit and not a JS edit), allow a
paste without truncation. That means that, in this case, we will return
`EditActionIgnored` instead of trying to truncate the string.
This behavior is controlled by a new preference `editor.truncate_user_pastes`
which is `false` by default (set in `StaticPrefList.yaml`).
We also modify `editor/libeditor/tests/test_bug603556.html` which currently
expects the output of a paste longer than maxlength to be truncated.
Testing: Created
`editor/libeditor/tests/test_pasting_text_longer_than_maxlength.html` which
checks if a user can paste a password longer than `maxlength` and if the field
is then marked as `tooLong` (this was the original concern of the reporter of
Bug 1320229), and
`editor/libeditor/tests/test_setting_value_longer_than_maxlength_with_setUserInput.html`
which checks if `eReplaceText` has consistent behavior regardless of whether the
field has an associated editor (this test works by calling `setUserInput()`
before and after the element gets focus.) `./mach test editor/libeditor` tests
pass.

It's inherited only by `PlaceholderTransaction` and used only for QI.
Therefore, we can get rid of it.
Additionally, this makes storing `PlaceholderTransaction` and
`CompositionTransaction` in `PlaceholderTransaction` faster and safer with
`WeakPtr`.
Finally, this makes `PlaceholderTransaction` always have non-null name
because it caused a lot of useless warnings in
`EditAggregationTransaction::GetName()` and
`PlaceholderTransaction::GetTxnName()`.

Users have much better, easier alternatives, like
DOMWindowUtils.{loadSheetUsingURIString,removeSheet}, which we use to
replace the only caller that exists in mozilla-central (the editor
element, which loads EditorOverride.css).
This allows to clean up the style system and editor. There are other
callers in comm-central, but it seems they can switch to DOMWindowUtils
trivially, as the DOMWindowUtils APIs also use the system principal and
thus they can load any URL.
I'll make sure to give them some time with the migration and/or help
out of course.

Due to the include hell, `EditorBase.h` cannot include `EditorUtils.h`.
Therefore we need these 3 methods once. Additionally, `IsModifiableNode()`
is really odd method and looks like that it's used for the following 2 purposes:
1. Simply can be editable.
2. Can be removed from parent.
For the former case, we should sort out it with
`EditorUtils::IsEditableContent()`, but for now, this patch moves it to
`HTMLEditUtils::IsSimplyEditable()`. On the other hand, for the latter case,
we obviously has a bug. Therefore, this patch creates
`HTMLEditUtils::IsRemovableFromParentNode()` and make it check whether the
removing node is also editable.
Unfortunately, `EditorUtils::IsEditableContent()` needs to take editor type.
But it's most callers are in `HTMLEditor` and most of remains are in
common methods of `EditorBase`. I guess we could remove this ugly argument
in the future.
