drm/i915: Import Linux commit 168f83660211b9e059e3bc0638daaa01e9ea0b71
This makes sure the default context of each ring is cleaned up with the
ring itself and fixes a memory leak.

drm/i915: unreference default context on module unload
Before module unload is called, gpu_idle() will switch
to default context. This will increment ref count of base
object as the default context is 'running' on module unload
time. Unreference the drm object so that when context
is freed, base object is freed as well.
v2: added comment to explain the refcounts (Ben Widawsky)

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.

An update for the i915 GPU driver, which brings the code up to Linux
commit 4d93914ae3db4a897ead4b. Some related drm infrastructure
changes are imported as needed.
Biggest update is the rewrite of the i915 gem io to more closely
follow Linux model, althought the mechanism used by FreeBSD port is
different.

drm/i915: Add HW context support
This feature is required by Mesa 9.2+. Without this, a GL application
crashes with the following message:
# glxinfo
name of display: :0.0
Gen6+ requires Kernel 3.6 or later.
Assertion failed: (ctx->Version > 0), function handle_first_current,
file ../../src/mesa/main/context.c, line 1498.
Abort (core dumped)
Now, Mesa 10.2.4 and 10.3-rc3 works fine:
# glxinfo
name of display: :0
display: :0 screen: 0
direct rendering: Yes
...
OpenGL renderer string: Mesa DRI Intel(R) 965GM
OpenGL version string: 2.1 Mesa 10.2.4
...
The code was imported from Linux 3.8.13.
