Jeff Brown e57e895080 Refactor input reader to support new device types more easily.
Refactored the input reader so that each raw input protocol is handled
by a separate subclass of the new InputMapper type.  This way, behaviors
pertaining to keyboard, trackballs, touchscreens, switches and other
devices are clearly distinguished for improved maintainability.

Added partial support for describing capabilities of input devices
(incomplete and untested for now, will be fleshed out in later commits).

Simplified EventHub interface somewhat since InputReader is taking over
more of the work.

Cleaned up some of the interactions between InputManager and
WindowManagerService related to reading input state.

Fixed swiping finger from screen edge into display area.

Added logging of device information to 'dumpsys window'.
