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.

If we render our UI around the composing text in the fullscreen
mode, probably we need to have our views under
android.R.id.extractArea, which is implemented as FrameLayout.
Therefore, using FrameLayout for the backing view makes it easy
to simplify the code between normal mode and full screen mode.

This is only informational data - it has no functional

RelativeLayout allows the IME to place its UI element at an
arbitrary position on the backing view.

Change-Id: Ib40d2111f56d8f38007e37c6c47536db3f0bef75

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.
