Adds a new virtualKeyQuietTimeMillis configuration resource that sets
the duration for which virtual keys will be dropped after recent touches
on screen. The default value is 0; it is intended to be overridden
per device using a resource overlay.
This change is designed to help in two cases:
1. Swipes from touchscreen into virtual key area.
2. Accidental taps in virtual key area while using on-screen keyboard.

Added support for loading the pointer icon from a resource.
Moved the system server related bits of the input manager out
of libui and into libinput since they do not need to be linked into
applications.
