fetching the selected text.

Bug: 2950652

Some refinements to correction behavior, such as retaining the tap-to-save
when in correction mode.

Use reflection to access the new InputConnection APIs with fallbacks, in case
we run on older OS versions.

Some refactoring to separate lookup for voice alternatives and typed alternatives.

It is easier to track each pointer if a PointerTracker object keeps
its pointer id.

The KeyDetector abstracts key detection algorithm. The
ProximityKeyDetector is one of its concrete implementations.  Another
one that might be called XAxisKeyDetector will follow to realize the
pop-up mini-keyboard behavior described in bug#2959169.

Also added a clean step, since it's only a Makefile change.

This change moves the following methods into KeyDebounce class.
- MotionEvent handling methods (onDownEvent etc.).
- Keyboard action event generator method (detectAndSendKey).
- Multi-tap key support methods (resetMultiTap etc.).
- Key preview text generator method (getPreviewText).

The change that makes KeyDebounce a top-level class will follow.

Extract key press and release handling out of previewKey() to
KeyDebouncer class. And pass Key object as argument of previewKey()
instead of key index.

- delete unused keyboard layout

Change-Id: Iab39446653460797f1ca876a7d9a23190c3a8df6

These three conditions assign true to the mAbortKey flag.
1. setKeyboard() sets the new keyboard layout.
2. long press shows the pop-up mini keyboard.
3. ACTION_CANCEL event is occurred.

In the case 1, in LatinIME so far, only "symbol key" and "language
switch" cause keyboard layout change.  In both cases, the event is
occurred in onUpEvent(), so we do not need to worry about aborting
event.

In the case 2, long press is used only to pop-up mini-keyboard and at that
time mMiniKeyboardOnScreen could be used as a flag.

In the case 3, though I'm not sure when this case occurs, in
onCancelEvent() all the things that should be canceled are canceled
in onCancelEvent().
