[mutter/wip/multitouchr: 29/73] devices: Make MetaDevice/MetaDeviceMap partly public

commit 13acafabe2ea0c2a66faa2b4d2d6a3448c2744d5
Author: Carlos Garnacho <carlosg gnome org>
Date:   Sun Jun 19 00:11:42 2011 +0200

    devices: Make MetaDevice/MetaDeviceMap partly public
    
    MetaDevice is quite limited outside of the core, mostly useful
    to represent a device, and get the paired one.
