Lucas Stach 8423d75d8f drm/nouveau: fix notify data leak
There is no reason to not free the notify data if the NTFY_DEL ioctl
failed. As nvif_notify_fini() is also called from the cleanup path of
nvif_notify_init(), the notifier may not have been successfully created
at that point. But it should also be the right thing to just free the
data in the regular fini calls, as there is nothing much we can do if
the ioctl fails, so better not leak memory.

Ben Skeggs a01ca78c8f drm/nouveau/nvif: simplify and tidy library interfaces
A variety of tweaks to the NVIF library interfaces, mostly ripping out
things that turned out to be not so useful.

- Removed refcounting from nvif_object, callers are expected to not be
  stupid instead.
- nvif_client is directly reachable from anything derived from nvif_object,
  removing the need for heuristics to locate it
- _new() versions of interfaces, that allocate memory for the object
  they construct, have been removed.  The vast majority of callers used
  the embedded _init() interfaces.
- No longer storing constructor arguments (and the data returned from
  nvkm) inside nvif_object, it's more or less unused and just wastes
  memory.

Ben Skeggs 5025407b98 drm/nouveau/core: namespace + nvidia gpu names (no binary change)
The namespace of NVKM is being changed to nvkm_ instead of nouveau_,
which will be used for the DRM part of the driver.  This is being
done in order to make it very clear as to what part of the driver a
given symbol belongs to, and as a minor step towards splitting the
DRM driver out to be able to stand on its own (for virt).

Because there's already a large amount of churn here anyway, this is
as good a time as any to also switch to NVIDIA's device and chipset
naming to ease collaboration with them.

A comparison of objdump disassemblies proves no code changes.

Ben Skeggs ef07ceae02 drm/nouveau/nvif: return null pointers on failure, in addition to ret != 0
Reported by Coverity.  The intention is that the return value is
checked, but let's be more paranoid and make it extremely obvious
if something forgets to.

Ben Skeggs a04d04231b drm/nouveau/nvif: import library functions for the ioctl/event interfaces
This is a wrapper around the interfaces defined in an earlier commit,
and is also used by various userspace (either by a libdrm backend, or
libpciaccess) tools/tests.

In the future this will be extended to handle channels, replacing some
long-unloved code we currently use, and allow fifo/display/mpeg (hi
Ilia ;)) engines to all be exposed in the same way.
