Jean-Sébastien Pédron 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.

Tested by:	Many people
MFC after:	1 month
Relnotes:	yes

* When allocating new object we first check if there is room at

* alloc_size. If so we allocate new object there.
*
* When there is not enough room at the end, we start waiting for
* each sub object until we reach object_offset+object_size >=
* alloc_size, this object then become the sub object we return.
*
* Alignment can't be bigger than page size.
*
* Hole are not considered for allocation to keep things simple.
