Fixes memory corruptions, oopses, etc. when multiple gpuobjs are
simultaneously created or destroyed.

Will be required by future work. Make the API change now to catch any
(but hopefully none) unexpected fallout.

This is a HUGE commit, but it's not nearly as bad as it looks - any problems
can be isolated to a particular chipset and engine combination. It was
simply too difficult to port each one at a time, the compat layers are
*already* ridiculous.
Most of the changes here are simply to the glue, the process for each of the
engine modules was to start with a standard skeleton and copy+paste the old
code into the appropriate places, fixing up variable names etc as needed.
v2: Marcin Slusarz <marcin.slusarz@gmail.com>
- fix find/replace bug in license header
v3: Ben Skeggs <bskeggs@redhat.com>
- bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and
left no space for kernel's requirements during GEM pushbuf submission.
- fix duplicate assignments noticed by clang
v4: Marcin Slusarz <marcin.slusarz@gmail.com>
- add sparse annotations to nv04_fifo_pause/nv04_fifo_start
- use ioread32_native/iowrite32_native for fifo control registers
v5: Ben Skeggs <bskeggs@redhat.com>
- rebase on v3.6-rc4, modified to keep copy engine fix intact
- nv10/fence: unmap fence bo before destroying
- fixed fermi regression when using nvidia gr fuc
- fixed typo in supported dma_mask checking

Having GPUOBJ and VM intertwined like this makes it *really* hard to
continue porting to the new driver architecture, split it out in
favour of requiring explit maps be the caller.
It's more flexible and obvious this way anyway...

These type of fake objects will not be supported for much longer.

A ton of duplication for the moment, will go away when they become subdevs.

Future work will be headed in the way of separating the policy supplied by
the nouveau drm module from the mechanisms provided by the driver core.
There will be a couple of major classes (subdev, engine) of driver modules
that have clearly defined tasks, and the further directory structure change
is to reflect this.
No code changes here whatsoever, aside from fixing up a couple of include
file pathnames.
