Because there may be very long key, such as space bar on tablet, we
should not use the distance between the touch point and the center of
key as proximity detection.  Instead of that, this change uses the
distance between the point and the nearest edge of key as proximity
detection.

Also this change fixes the bug that space key (code 32) was not
counted in proximity detection.

Cherrypick I44f3b2eef8086d6e0b0db53d38f08487549060c6 from Gingerbread

This change also introduces the key background drawables which has no
fixed bottom padding.  Instead of relying on bottom padding in
drawable, this change also specifies Keyboard.verticalGap with
physical unit.  Other keyboard related length, distance and size are
also specified by physical unit.
