Make inteldrm(4) attach to pci(4) instead of vga(4) just like radeondrm(4).
This is needed for machines where Intel graphics isn't the primary graphics
device and on systems with UEFI firmware that put the device in non-VGA mode.

Add a port of the TTM and Radeon DRM code from Linux 3.8.13.
Includes kernel modesetting, framebuffer console and support
for newer hardware.

Firmware needs to be present for acceleration and in some cases
modesetting to work. It can be installed via fw_update
or manually via pkg_add.

With lots of help from kettenis@ some macppc bits from mpi@
and some ttm refcount/queue bits from FreeBSD.

Thanks to M:Tier and the OpenBSD Foundation for sponsoring this work.

Provide a way for *drm(4) to prevent the VGA text console wsdisplay(4) instance
from attaching after it has taken over control of the VGA hardware.

ok mpi@

Split out the bar functions required to attach drm(4) to share them
with macppc's vgafb(4) and maybe later on sparc64 drivers too.

Try to save the vga hardware state around suspend, and also redisplay the

Updated VGA driver; from NetBSD. Needed for wscons on i386 and alpha. These
files could probably be updated even a bit further (they are from mid-summer).

In addition, I've added support for console scrollback, somewhat inspired by
Linux's vgacon driver. Basically, instead of allocating our own buffer and
doing lots of copies, we take advantage of Video RAM and just modify the VGA
display origin register as appropriate. This approach has a few advantages:
simple to implement, no wasted KVM, it's fast, and after a boot you can now
scroll back all the way to the BIOS messages (assuming your msgbuf is of a
typical length :). Disadvantages are that the VRAM buffer is relatively
small (only 32k) and we do not support raster devices through this method.
(thanks to mickey@ for pointing this out).

The code for this is fairly unobtrusive, so should we come up with a better
approach to console scrollback at a later time (i.e., even more platform
independent) it should be easy to revert this.

We're one step further in porting nice features of PCVT over to wscons.
