Patch file for improving KMSDRM reliability

This patch improves the reliability of the KMSDRM video backend by changing two things:
1. The video backend will look for more than one video card checking whether connectors are available, matching Weston behaviour and allowing it to work reliably in multi-card configurations.
2. The video backend will try setting itself as DRM master of the device file, aborting if it can't set itself as DRM master. Intended to fix bugs if the X11 server/Wayland compositor is active as DRM master.
