Revamp of the NumberPicker widget.

1. The number picker no longer shows up and down arrows, it
   has only three touch targets which are the currently selected number
   in the middle with a lesser one above and greater below, now what
   you touch is what you get, flingability and long press are still
   supported.

2. Removed the restriction for a View with an AccessibilityNodeProvider
   to not have any concrete children. If the View has a provider, then
   this provider is responsible for creating the AccessibilityNodeInfos
   for all its descendants, concrete and virtual. The number picker is
   a good example for such a case - it has a concrete input view and
   two virtual buttons as its children. This is a safe change since
   this behavior has not been released.

3. This patch also fixes bug where the number picker is stretched too
   much in the Theme theme.
