Use HAVE_NVMM for nvmm headers

Revert previous to make iscsi kernel headers optional again, as
required by kamil.

Now, sanitizer in GCC9 has been fixed differently for MKISCSI=no.

Unconditionally install kernel headers for iSCSI as required by
sanitizer shipped with GCC9.

Fix build release with HAVE_GCC=9 for sun2, where MKISCSI=no by default.

Remove filemon(4).

Discussed on tech-kern:
https://mail-index.NetBSD.org/tech-kern/2020/01/13/msg025938.html

This was never (intentionally) enabled by default, and the design has
some shortcomings.  You can get mostly the same results with ktrace,
as in usr.bin/make/filemon/filemon_ktrace.c which is now used instead
of filemon for make's meta mode.

If applications require higher performance than ktrace, or nesting
that ktrace doesn't support, we might consider adding something back
into the vfs system calls themselves, without hijacking the syscall
table.  (Might want a more reliable output format too, e.g. one that
can handle newlines in file names.)

Revert the removal of filemon.

Retire filemon, discussed on tech-kern@.

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.

Fix fallout from hid factorisation:
- need to install sys/dev/hid/hid.h for userland
- include it where needed - most of the time in place if usb/usbhid.h

Make the test for MKISCSI actually work by including bsd.own.mk and
testing the expanded variable, not just the variable name(!)  Fixes the
build for sun2.

Build and install new in-kernel iscsi initiator kernel module and associated
binaries (iscsid, iscsictl) if MKISCSI != no.  Initiator can also be built
into a kernel by adding 'pseudo-device iscsi' in kernel configuration.

Install dev/i2c/i2c_io.h and implement the API in the iic(4) driver.
Obsolete the I2C_SCAN option as this can now be done from userland.

Import of device-mapper driver. This driver is BSD rewrite of linux dm driver.
For now only error, linear and zero targets are supported. This driver uses NetBSD
specific ioctl protocola based on proplib.

I was able to create logical volume (with lvm2tools lvcreate utility) with this
version of driver, newfs it and mount it.

Rename the dctl psuedo-device to devfsctl after discussion on tech-kern.

If you are running a devfs-enabled kernel, please update your config to
use devfsctl instead of dctl.

Start where the mjf-devfs branch left off.

Add some devfs code that's been sitting in my local tree for a while.

devfsd(8) is now the first daemon to be started after init(8). It tracks
device insertion (will eventually track removal) and devfs mounts.

Currently, we can mount multiple device file systems and have device
special files pushed into the mounts automatically, though, the device
special files aren't created with the correct major/minor number pairs
yet.

More work to come soon.

Abstract the interface between pckbc(4), and the pckbd(4) and pms(4)
drivers that attach to it.  This allows for other host interface chips
that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111.  The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers.  To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned.  Thy just use rather more function pointers than before.  Tested
on i386 and (with a new host driver) acorn32.  Compiled on several other
affected architectures.

The file system snapshot pseudo driver.

Uses a hook in spec_strategy() to save data written from a mounted
file system to its block device and a hook in dounmount().

Not enabled by default in any kernel config.

This is the "kttcp" network throughput testing pseudo-device.  From
the block comment at the top of the file:

      This module provides kernel support for testing network
      throughput from the perspective of the kernel.  It is
      similar in spirit to the classic ttcp network benchmark
      program, the main difference being that with kttcp, the
      kernel is the source and sink of the data.

      Testing like this is useful for a few reasons:

      1. This allows us to know what kind of performance we can
         expect from network applications that run in the kernel
         space, such as the NFS server or the NFS client.  These
         applications don't have to move the data to/from userspace,
         and so benchmark programs which run in userspace don't
         give us an accurate model.

      2. Since data received is just thrown away, the receiver
         is very fast.  This can provide better exercise for the
         sender at the other end.

      3. Since the NetBSD kernel currently uses a run-to-completion
         scheduling model, kttcp provides a benchmark model where
         preemption of the benchmark program is not an issue.

There is a companion "kttcp" user program which uses the kttcp
pseudo-device.

Largely written by Frank van der Linden, with some modifications
from me.

Put back all header files defining ioctls

Only install headers which are actually used by our userland. This
saves about 2.2MB under /usr/include/dev/. Discussed on tech-kern@
recently.

I HOPE to get the list right. The headers I left in are ones
used for MI tools and those whose usage I discovered by grep over tree sources.
Feel free to put needed includes back in if you encounter anything which
should not be removed from lists.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as

Rework the way kernel include files are installed.  In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
