[PATCH v9 0/6] Make Weston multiseat aware

[nerdopolis]

These patches make Weston handle multiple seats. Fixes from the last 
attempt include updating fbdev_set_screen_info , updating some fuzz,
and making the selection of the framebuffer device similar to 
compositor-drm.c by favoring the boot_vga device, and making
requested changes. These now address some memory leaks, and other 
changes requested.
