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.

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.

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().

This change will display the key board preview instantaneously when
the key is pressed. Dismissing the key preview will be delayed
slightly after the key is released, as we do now.
Because in multi touch mode, we should instantaneously change keyboard
layout when modifier key, such as shit and symbol, is pressed.

This change eliminates the need of extra MotionEvent allocation. Also
this will lead to the easy way to handle multi touch events.

GestureDetector listener's onFling method will not call detectAndSendKey
anymore.
Make gesture detector be ignoring multitouch. Refactoring
GestureDetector out of LatinKeyboardBaseView class change will follow.

This change encapsulates mInKeyRepeat (former mRepeatKeyIndex) into
UIHandler class. Also this eliminates mCurrentKey and mLastTapTime
dependency from repeatKey method.

This change simplifies onModifierTouchEvent to focus on handling
motion event related to a key event.
Other refactoring will follow in order to support multi touch.
