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.

The symlinks were annoying some people, and they're not used anywhere
else in the kernel tree.  The include directory structure has been
changed so that symlinks aren't needed anymore.

NVKM has been moved from core/ to nvkm/ to make it more obvious as to
what the directory is for, and as some minor prep for when NVKM gets
split out into its own module (virt) at a later date.

Has additional safeties for one.  For two, needed for an upcoming
commit that removes abuse of nouveau_object.engine.

A bit different from NVIDIA's RFC patch, but I want this now for GM107.

Since alarms don't play well with suspend, it is important every alarm
user cancels his tasks before suspending.

The task should be rescheduled on resume.

This is needed for automatic fan management where some delays
can be over 0xffffffff ns.
