When CursorAnchorInfo is unavailable, we shouldn't try to show
the commit indicator and set the text highlight color.

With this CL, RichInputConnection can be used to track if the
application responded that it does support CursorAnchorInfo or
not.  This result will be taken into consideration when
InputLogic needs to determine whether the commit indicator
should be displayed or not.

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 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.

There is a bug in ICS where the input connection won't take
any writing commands after rotation until the cursor moves.
This fixes it by wiggling the cursor position once before trying
to do anything.

It's probably cleaner to just pass the events rather than read
them from a transaction, especially when a transaction may be
associated with several events in a chain.

Formerly "Show correction suggestions" had three options, "always
show", "show in portrait mode", and "always hide". The reason behind
"show in portrait mode" was that there may not be enough screen estate
in landscape mode to show suggestions. Because recent phone devices
have relatively large screen, we decide to remove "show in portrait
mode" option.

...otherwise we can't recompute the composition when we
change scripts.

This also fixes when we register that we need to take note
that the current subtype was used. Luckily this is a good
occasion for some cleanup that I've wanted to do for some
time: use InputTransaction for onTextInput (with the goal
to ultimately remove it entirely)
