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.

For avoiding confusion between API of `nsRange` and `StaticRange`, I'd like to
rename `nsRange::CreateRange()` to `nsRange::Create()` because
`StaticRange::CreateStaticRange()` is too long name and
`StaticRange::CreateRange()` sounds odd. This patch renames it and changes
related methods to template methods to avoid runtime cost of temporary
`RawRangeBoundary` instance creation.

`PresShell.h` is exposed as `mozilla/PresShell.h` and `PresShell` is the only
concrete class of `nsIPresShell`. Therefore, we have no reason to access
`PresShell` via `nsIPresShell`.

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.

This method is not a virtual call, and also looks nicer.
This patch was mostly generated by a Python script, but I manually
cleaned up the code in a few places where statements didn't need to be
split across multiple lines any more.

EditorBase::CreateTxnForComposition() just hides what it does. For its caller,
creating a factory method, CompositionTransaction::Create(), is clearer what
it does.
Additionally, capsuling the creation in CompositionTransaction class can make
the text node information in TextComposition updated automatically. So, now,
it might be better to update them in DoTransaction() because there is a lag
between creating the transaction and calling DoTransaction(). However, this
patch doesn't want to change any existing behavior. So, this doesn't fix this
issue.

Most arguments of the constructor of CompositionTransaction are now stored by
EditorBase::mComposition. So, making it take TextComposition reduces the
number of its arguments.
Note that this patch doesn't make it retrieve TextComposition with
EditorBase::GetComposition() for guaranteeing that the editor has non-nullptr
mComposition.

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.

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.
