We have two consumers of relocations. One is static state buffers, which
want the same relocation every time. The other is the batchbuffer, which gets
thrown out immediately after submit. This lets us reduce repeated computation
for static state buffers, and clean up the code by moving relocations nearer
to where the state buffer is computed.

This is currently believed to work but be a significant performance loss.
Performance recovery should be soon to follow.
The dri_bo_fake_disable_backing_store() call was added to allow backing store
disable like bufmgr_fake.c did, which is a significant performance win (though
it's missing the no-fence-subdata part).
This commit is a squash merge of the 965-ttm branch, which had some history
I wanted to avoid pulling due to noisiness and brokenness at many points
for git-bisecting.

The uint64_t flags (as defined by drm.h) were being used as unsigned ints in
many places.

This is required for 965 support, which has relocations in other places than
just the batchbuffer.

gears now runs for about 10-15 seconds with some artifacts before falling

This moves the relocations into the buffer manager in prepration for
a superioctl move.

|
This removes the use of fake buffers from the driver, such that it could
probably be removed from the interface. It also should assist in proper
synchronization of access.

Now, allocations only take locations, rather than a variety of unused flags.
The only interesting flag before was the no_move/no_evict pair for scanout
and similar buffers, which the DRI drivers don't use. That will be readded
when we get to using this code for display buffer allocation, by adding a
pin/unpin call (dynamic pinning/unpinning may be useful for VT switching and
root window resizing).
This commit changes one instance of DRM_BO_FLAG_MEM_LOCAL with
DRM_BO_FLAG_MEM_TT, which appeared to have been unintentional.

The interface is not solid yet (some simplification to do still, and
adjustment for 0-copy), and the drivers are not converted. However, the new
interface allows using the same calls to support either a TTM or a classic
static allocation backend, with the static backend allowing a more limited
feature set.
