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 was used to make all ioctl handlers return -errno on linux and errno on
*BSD. Instead, just return -errno in shared code, and flip sign on return f
shared code to *BSD code.

Bugzilla Bug #9457
Add refcounting of user waiters to the DRM hardware lock, so that we can use
DRM_LOCK_CONT flag more conservatively.
Also add a kernel waiter refcount that if nonzero transfers the lock for the
kernel context when it is released. This is useful when waiting for idle and can be used for very simple fence object driver implementations for the new memory manager

Add support for the SiS 315 to the DRM.

This add support to the SiS and VIA drivers for the simple memory manager.
This fixes a lot of problems with the current simple code these drivers used,
including locking and SMP issues.

Rename the driver hooks in the DRM to something a little more understandable:
preinit -> load
postinit -> (removed)
presetup -> firstopen
postsetup -> (removed)
open_helper -> open
prerelease -> preclose
free_filp_priv -> postclose
pretakedown -> lastclose
postcleanup -> unload
release -> reclaim_buffers_locked
version -> (removed)
postinit and version were replaced with generic code in the Linux DRM (drivers
now set their version numbers and description in the driver structure, like on
BSD). postsetup wasn't used at all. Fixes the savage hooks for
initializing and tearing down mappings at the right times. Testing involved at
least starting X, running glxgears, killing glxgears, exiting X, and repeating.
Tested on: FreeBSD (g200, g400, r200, r128)
Linux (r200, savage4)

Finally cleaned up the sparse warnings for the drm.

I've been threatening this for a while, so no point hanging around.
This lindents the DRM code which was always really bad in tabbing department.
I've also fixed some misnamed files in comments and removed some trailing
whitespace.

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!
