"get_transfer + transfer_map" becomes "transfer_map".
"transfer_unmap + transfer_destroy" becomes "transfer_unmap".
transfer_map must create and return the transfer object and transfer_unmap
must destroy it.
transfer_map is successful if the returned buffer pointer is not NULL.
If transfer_map fails, the pointer to the transfer object remains unchanged
(i.e. doesn't have to be NULL).

Nothing uses it now.

The primary motivation for this rewrite was to have a maintainable driver
going forward, as nvfx was quite horrible in a lot of ways.
The driver is heavily based on the design of the nv50/nvc0 3d drivers we
already have, and uses the same common buffer/fence code. It also passes
a HEAP more piglit tests than nvfx did, supports a couple more features,
and a few more to come still probably.
The CPU footprint of this driver is far far less than nvfx, and translates
into far greater framerates in a lot of applications (unless you're using
a CPU that's way way newer than the GPUs of these generations....)
Basically, we once again have a maintained driver for these chipsets \o/
Feel free to report bugs now!
