NANDFS has been broken for years. Remove it. The NAND drivers that
remain are for ancient parts that are no longer relevant. They are
polled, have terrible performance and just for ancient arm
hardware. NAND parts have evolved significantly from this early work
and little to none of it would be relevant should someone need to
update to support raw nand. This code has been off by default for
years and has violated the vnode protocol leading to panics since it
was committed.

Add a CAM-Newbus SDIO support module. This works provides a newbus
infrastructure for device drivers wanting to use SDIO. On the lower end
while it is connected by newbus to SDHCI, it talks CAM using the MMCCAM
framework to get to it.
This also duplicates the usbdevs framework to equally create sdiodev
header files with #defines for "vendors" and "products".

The source file was moved to base earlier and also improved upon,
but never compiled in. This patch will:
- Make a module in sys/modules
- Make lindebugfs depend on linuxkpi (for seq_file)
- Check if read/write functions are set before calling, DRM drivers
don't always set both of them.

tun(4) and tap(4) share the same general management interface and have a lot
in common. Bugs exist in tap(4) that have been fixed in tun(4), and
vice-versa. Let's reduce the maintenance requirements by merging them
together and using flags to differentiate between the three interface types
(tun, tap, vmnet).
This fixes a couple of tap(4)/vmnet(4) issues right out of the gate:
- tap devices may no longer be destroyed while they're open [0]
- VIMAGE issues already addressed in tun by kp
[0] emaste had removed an easy-panic-button in r240938 due to devdrn
blocking. A naive glance over this leads me to believe that this isn't quite
complete -- destroy_devl will only block while executing d_* functions, but
doesn't block the device from being destroyed while a process has it open.
The latter is the intent of the condvar in tun, so this is "fixed" (for
certain definitions of the word -- it wasn't really broken in tap, it just
wasn't quite ideal).
ifconfig(8) also grew the ability to map an interface name to a kld, so
that `ifconfig {tun,tap}0` can continue to autoload the correct module, and
`ifconfig vmnet0 create` will now autoload the correct module. This is a
low overhead addition.
(MFC commentary)
This may get MFC'd if many bugs in tun(4)/tap(4) are discovered after this,
and how critical they are. Changes after this are likely easily MFC'd
without taking this merge, but the merge will be easier.
I have no plans to do this MFC as of now.

Embedded lzma decompression library becomes a module usable by other
consumers, in addition to geom_uzip.
Most important code changes are
- removal of XZ_DEC_SINGLE define, we need the code to work
with XZ_DEC_DYNALLOC;
- xz_crc32_init() call is removed from geom_uzip, xz module handles
initialization on its own.
xz is no longer embedded into geom_uzip, instead the depend line for
the module is provided, and corresponding kernel option is added to
each MIPS kernel config file using geom_uzip.
The commit also carries unrelated cleanup by removing excess "device geom_uzip"
in places which were missed in r344479.

iflib is already a module, but it is unconditionally compiled into the
kernel. There are drivers which do not need iflib(4), and there are
situations where somebody might not want iflib in kernel because of
using the corresponding driver as module.

I also learned that 'mips' is overly broad and covers 64bit architectures
too. However, it's not worth the fight right now, so any refinements
will have to come another day.
mpr as a module for powerpc or mips. An upcoming commit will cause these
drivers to rely on the presence of 64bit atomic operations. Discussed
with jhibbits.
I held the mistaken belief this was completely unused. While the
driver is unused and likely not relevant for a long time,
sys/joystick.h lives on in maybe half a dozen ports, even though
hardware to use it hasn't been widely used in maybe 15 years.
This driver has been obsolete since the FreeBSD 4.x. It should have
been removed then since the sym(4) driver had subsumed it. The driver
was commented out of GENERIC in 2000.

scsi_low was a common set of routines to do the SCSI bus sequencing
for the ncv, nsp and stg drivers. Those have been removed, so it's no
longer needed since nothing else in the tree uses it and nothing
likely ever will (it's for super-low-end 8-bit parallel SCSI cards).
stg(4) is marked as gone in 12. Remove it. There are no sightings of
it in the nycbug dmesg database. It was for an obscure SCSI card that
sold mostly in Japan, and was especially popilar among pc98 hackers in
the 4.x time frame. It was also only enabled on i386.
