There is no reason that SetTextRangeStyle is defined at nsISelectionPrivate. Also, SetTextRangeStyle isn't scriptable, and is called from CompositionTransaction::SetIMESelection only. So we should move this to Selection.

CompositionTransaction forgets to call EndBatchChanges when GetSelectionController returns error, so we should use RAII class instead.

Edit transactions should store their editor instance with strong reference and they should be released at destroying the editor.

Although PlaceholderTransaction will use the selection on Merge, it is too late to use UpdateRange. Because RangeUpdater will be used after DoTransaction is finished. So we should update selection on DoTransaction.
Also, part 1 fix doesn't update selection correctly via RangeUpdater when IME composition is multiple node.

Google Keep uses range.insertNode on input event. So, text node will be inserted into current caret position.
Microsoft IME's caret is after composition string, but ATOK's caret is before it. So when using ATOK, this issue occurs. By range.insertNode, text nodes that have IME attribute becomes multiple text nodes. But CompositionTransanction doesn't consider that IME range isn't single text node. Although it replaces current composition string with new string on first text node, it doesn't delete composition string on other text node.

In our coding rules, variable names of nsresult should be rv. Indeed, when you see |rv| in the code, you must assume that its type if nsresult.
However, a lot of code under editor/ uses |res| for the variables of nsresult. Let's replace |res| with |rv|.
And this patch improves following points:
1. When |rv| is set in both |if| and |else| block and they are check outside of them, this moves the check into each |if| and |else| block because even if the failure is notified with warning, you cannot see which case was performed and failed. This change makes it clear.
2. When |return rv;| returns non-error code because |rv| is checked with NS_ENSURE_SUCCESS() immediately before, setting replacing it with |return NS_OK;| is clearer.
3. Move declaration of |nsresult rv| into smaller scope as far as possible. This prevents setting rv to unexpected value and easier to check its value at reading the code.

CompositionTransaction::SetIMESelection() is also called when user redos the committed composition. In such case, it doesn't have ranges, but DoTransaction() tries to restore selection ranges with no ranges. That causes hiding caret because when there is no caret range in the ranges, SetIMESelection() hides the caret as IME requested.
So, for redo, SetIMESelection() shouldn't hide caret when there are no ranges (i.e., the composition was already committed).
This patch also renames:
EditorInputEventDispatcher -> mozilla::EditorInputEventDispatcher
And some variable names are renamed from aEditor or mEditor to aEditorBase or mEditorBase for making their types clearer.

This patch renames IMETextTxn to CompositionTransaction. "Composition" is now used in some web standard specs, e.g., CompositionEvent defined by UI Events.
This patch also renames nsEditor::CreateTxnForIMEText() to nsEditor::CreateTxnForComposition().
