455fa6518a 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.

ea4447500d - Remove test_and_set_bit() macro. It is unused since r255037.
- Relax atomic_read() and atomic_set() macros.  Linux does not require any
memory barrier.  Also, these macros may be even reordered or optimized away
according to the API documentation:

e27f871969 Add the code for new Intel GPU driver, which supports GEM, KMS and
works with new generations of GPUs (IronLake, SandyBridge and
supposedly IvyBridge).

The driver is not connected to the build yet.
