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

Browse Source 
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.

Tested by:	Many people

/**
* \mainpage
*
* The Direct Rendering Manager (DRM) is a device-independent kernel-level
* device driver that provides support for the XFree86 Direct Rendering
* Infrastructure (DRI).
*
* The DRM supports the Direct Rendering Infrastructure (DRI) in four major
* ways:
* -# The DRM provides synchronized access to the graphics hardware via
* the use of an optimized two-tiered lock.
* -# The DRM enforces the DRI security policy for access to the graphics
* hardware by only allowing authenticated X11 clients access to
* restricted regions of memory.
* -# The DRM provides a generic DMA engine, complete with multiple
* queues and the ability to detect the need for an OpenGL context
* switch.
* -# The DRM is extensible via the use of small device-specific modules
* that rely extensively on the API exported by the DRM module.
