With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.
This restructures the drm along the lines of other kernel components.
It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.

This reverts commit ac741ab71b.
Okay this looks like wasn't as fully baked as I'd led myself to believe.
Revert for now for further baking.

This re-works the DRM internals to provide a better interface for drivers
to expose vblank on multiple crtcs.
It also includes work done by Michel on making i915 triple buffering and pageflipping work properly.

This moves a bunch of typedefs into a !defined __KERNEL__ to keep userspace
API compatiblity, it changes all internal usages to structs/enum/unions.

These require that the status page be referenced by a pointer in GTT, rather
than phsyical memory. So, we have the X Server allocate that memory and tell
us the address, instead.

of pipe number.
Handle relative as well as absolute target sequence numbers.
Return error if target sequence has already passed, so userspace can deal with
this situation as it sees fit.
On success, return the sequence number of the vertical blank when the buffer
swap is expected to take place.
Also add DRM_IOCTL_I915_VBLANK_SWAP definition for userspace code that may want
to use ioctl() instead of drmCommandWriteRead().

This uses the core facility to schedule a driver callback that will be called
ASAP after the given vertical blank interrupt with the HW lock held.

i915 vblanks can be generated from either pipe a or b, however a disabled
pipe generates no interrupts. This change allows the X server to select
which pipe generates vblank interrupts.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
