Log:
  drm: Update the device-independent code to match Linux 3.8.13

  This update brings few features:
      o  Support for the setmaster/dropmaster ioctls. For instance, they
         are used to run multiple X servers simultaneously.
      o  Support for minor devices. The only user-visible change is a new
         entry in /dev/dri but it is useless at the moment. This is a
         first step to support render nodes [1].

  The main benefit is to greatly reduce the diff with Linux (at the
  expense of an unreadable commit diff). Hopefully, next upgrades will be
  easier.

  No updates were made to the drivers, beside adapting them to API
  changes.

  r280814 is merged at the same time to avoid a short window where RANDR
  might be broken:

  drm: Import Linux commit 9bc3cd5673d84d29272fa7181a4dfca83cbb48c1

      drm: Sort connector modes based on vrefresh

      Keeping the modes sorted by vrefresh before the pixel clock makes the
      mode list somehow more pleasing to the eye.
