Add NVMM - for NetBSD Virtual Machine Monitor -, a kernel driver that
provides support for hardware-accelerated virtualization on NetBSD.

It is made of an MI frontend, to which MD backends can be plugged. One
MD backend is implemented, x86-SVM, for x86 AMD CPUs.

We install

	/usr/include/dev/nvmm/nvmm.h
	/usr/include/dev/nvmm/nvmm_ioctl.h
	/usr/include/dev/nvmm/{arch}/nvmm_{arch}.h

And the kernel module. For now, the only architecture where we do that
is amd64 (arch=x86).

NVMM is not enabled by default in amd64-GENERIC, but is instead easily
modloadable.

Sent to tech-kern@ a month ago. Validated with kASan, and optimized
with tprof.
