Replace r300_check_offset() with generic radeon_check_offset(), which doesn't
reject valid offsets when the framebuffer area is at the very end of the card's
32 bit address space. Make radeon_check_and_fixup_offset() use
radeon_check_offset() as well.
This fixes https://bugs.freedesktop.org/show_bug.cgi?id=7697 .
only allow specific type-3 packets to pass the verifier instead of all for r100/r200 as others might be unsafe (r300 already does this), and add checking for these we need but aren't safe. Check the RADEON_CP_INDX_BUFFER packet on both r200 and r300 as it isn't safe neither.

This code reworks the radeon memory map so it works better
for newer r300 chips and for a lot of older PCI chips.
It really requires a new X driver in order to take advantage of this code.

The Xgl on r300 doesn't work unless you add a verify bitblt function to the
DRM, and we need to pass TX_CNTL to flush texture caches.

This patch pull in a lot of changes from CVS to the main core DRM,
and updates the radeon driver to 1.21.0 that supports r300 texrect
and radeon card type ioctl.

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.

This adds initial r300 3D support to the radeon DRM.
