MAKEDEV: make nvmm node group-writable (was readable only; group nvmm)

/dev/ttyVI??

Tested under qemu with:

qemu-system-aarch64 ... \
-device virtio-serial \
-chardev socket,path=/tmp/ttyVI00,server=on,wait=off,id=ttyVI00 \
-device virtconsole,chardev=ttyVI00,name=org.NetBSD.dev.ttyVI00 \
...

I updated MAKEDEV.conf to create /dev/ttyVI?? on all ports where it
looks likely to work based on:
(a) having pci or a non-pci virtio attachment,
(b) `qemu-system-$ARCH -M ?' mentioned something resembling the port,
and
(c) `qemu-system-$ARCH -device virtio-serial' launched without
complaining about the virtio-serial device.

(Criterion (c) excluded sparc and sparc64.)

on wsfont(4) device opened for writing and relied on its restrictive
root-only permissions to restrict who can load fonts.

A driver and user land utility for the Sparkfun Serial Controlled Motor
Driver module as illustrated here:

https://www.sparkfun.com/products/13911

A SCMD module is a ARM SOC simular to a Arduino in front of a motor
driver chip. The single SCMD module can control two motors and up to
16 additional modules can be chained together using an internal I2C
bus. One can interface with the SCMD using tty uart commands, SPI or
I2C. The driver in this commit adds a kernel driver for the I2C and
SPI interfaces. The command line utility provides a set of
convenience commands that support most of the functions of the SCMD
and is able to use the tty uart mode, SPI user land or the included
kernel driver in a uniform manor.

The use of the SCMD module is mostly for small robots and the like,
but it can control anything that is controllable by voltage.

efi: Add /dev/efi character device

Introduce a /dev/efi character device that provides a means for accessing
UEFI RT variable services from userland. Compatible with the FreeBSD ioctl
interface for ease of porting their libefivar and associated tools.

The ioctl interface is defined in sys/efiio.h.

To enable support for this on an arch, the kernel needs `pseudo-device efi`
and the MD EFI implementation needs to register its backend by calling
efi_ops_register(). This commit includes an implementation for Arm.

Remove uscanner(4) driver

This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going
back to 2004 where the usefulness of this driver is discussed, but
the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.

acpi: add character device for accessing ACPI tables

The /dev/acpi character device gives an aperture into physical memory
that allows only read access to known ACPI tables: RSDP, XSDT/RSDT, and
the root tables. Adapt acpidump(8) to use this interface by default,
falling back to the old /dev/mem method if it is not available or if
ACPIDUMP_USE_DEVMEM=1 is set in the environment. The user visible benefit
of this change is that "options INSECURE" is no longer required to
dump ACPI tables.

add support for wwanc(4) device nodes (xmm[0-9])

Add fault(4).

Register eight vHCI buses, and use separate KCOV mailboxes for them.

remove nsmb(4)

Create the qemufwcfg device as part of "all". Discussed with jmcneill.
Also, include it in the list of special purpose devices.

Create /dev/ipmi0 in `MAKEDEV all'.

Works on my machine with sysutils/ipmitool if the latter is built
with CONFIGURE_ARGS+= --enable-intf-open.

Create some more cgd device nodes.

remove urio(4), a driver for the Rio500 MP3 player.

At this point it is highly unlikely this 1999 device still has users,
but it still comes up in the context of maxv's USB-fuzzing (and any device
could pretend to be a urio(4)), so it's best to get rid of it.

Renamed all major entries to obsolete, as was done in previous removals.

This still requires an update to sanitizers, but they're located in
"external", perhaps it should be first committed upstream?

Proposed on tech-kern a month ago.

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.)
