This is an optional optimization to reduce the UI latency.

Imagine that the commit indicator is now displayed and the
composing text is being updated, it is highly likely that
the commit indicator will disappear unless the application
rejects the setComposingText request.

If we assume that the application will accept the new
composing text without any modifications, we can hide the
indicator without waiting for the arrival of new
CursorAnchorInfo event.

This optimization isn't dangerous because we can show the
indicator again when we receive new CursorAnchorInfo event
and the assumption is turned out to be invalid.

This CL introduces commit/add-to-dictionary indicators.

Note that the text is not yet highlighted when the commit
indicator is displayed. It will be addressed in subsequent
CLs.

This is because prediction can't be easily distinguished in
style. This fixes the bug by simulating the right members,
but some refactoring should be done to remove useless
booleans.

This is a groundwork for subsequent CLs where we need to

change any existing behaviors.

This CL slightly extends the condition when "Add to dictionary"
hint is dismissed.

With this CL, "Add to dictionary hint" will be dismissed by any
non-special char event. This is more comfortable especially if
we start using more intrusive UIs such as indicator and/or
background color with the text hint in the suggestion strip.

This is a groundwork for subsequent CLs where we need to
add/remove background color to/from the commited text.

In this CL, we use Spanned#SPAN_COMPOSING so that we can easily
remove such a background color by calling
InputConnection#finishComposingText. To make this operation easy
and realiable, we need to track whether we have specified the
background color to the commited text or not at one place. Here
we use RichInputConnection for this purpose.

This CL simply moves the method calls of #requestCursorAnchorInfo
into #onStartInputInternal just to consolidate the logic.

Change-Id: Ia205738b9614e9ae375c1dab767a91d2e1f6d0d3

This CL add more compatibility wrapper methods for
CursorAnchorInfo.

This CL also adds more utility functions and types into
CompatUtils to reduce explict cast operations.

(cherry picked from commit fb74ab15)

With this CL, the backing view starts covering the content area
entirely.  This allows the IME to render its UI elements at an
arbitrary position on the screen.
