And also this patch makes its only user,
`EditorBase::InsertTextIntoTextNodeWithTransaction`, and its only caller,
`EditorBase::InsertTextWithTransaction`, return `InsertTextResult` for
returning both end of inserted text and caret point suggestion. Note that
if it's for IME composition, `CompositionTransaction` needs to update
`Selection` directly. Therefore, caret point may be unset under composition
to updating `Selection` to wrong point (it seems that
`TextEditor::HandleInsertText` can be simplified later because of this change).

First, move methods of `HTMLEditor` which collapse `Selection` to `EditorBase`.
Then, make editor stop accessing `Selection::CollapseInLimiter` directly.

Currently, when `HTMLEditor` replaces text in a text node, `HTMLEditor`
creates a set of `DeleteTextTransaction` and `InsertTextTransaction`.
However, this has bad impact for footprint and causes the callers messy.
This patch creates `ReplaceTextTransaction` instead and
`HTMLEditor::ReplaceTextWithTransaction()` as its wrapper. Unfortunately,
this becomes not calling `nsIEditActionListener::DidDeleteText()`, however,
this is not used by mozilla-central, comm-central nor BlueGriffon. IIRC,
it was not removed for some legacy addons of Thunderbird. Therefore, it
must be okay to remove it.

In a lot of places in libeditor, we do nothing if given transaction is not
our edit transaction classes' instance. Therefore, it's better to have
casting virtual method in `nsITransaction` for performance because QI cost
may not be cheap.

In the next patch, we need to update unmasked range when anonymous text node
in `<input type="password">` is modified. This patch makes editor manage it
easier to update the range.
Note that the next patch also handles text node creation and destruction.

Using concrete class types with static IIDs in QueryInterface methods is a
pretty common pattern which isn't supported by any existing helper macros.
That's lead to separate ad-hoc implementations, with varying degrees of
dodginess, being scattered around the tree.
This patch adds a helper macro with a canonical (and safe) implementation, and
updates existing ad-hoc users to use it.

EditorBase::CreateTxnForInsertText() just hides what it exactly does.
Rewriting it with a static factory method, InsertTextTransaction::Create()
should be clearer for its caller.

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.

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.

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.
