com.klarasystems:vdev_zaps_v2 is a new feature that the last OpenZFS
import brought in. It needs to be on the list of supported features, but
that update didn't happen so I woke up to a mailbox with multiple

Add some more sanity checks to make sure we don't march off the end of
the table. Typically, smbios structures are well formed, or Windows
wouldn't boot. Sometimes they aren't, and this at least fails safe.

This code was written on x86 where unaligned accesses were
easy. LinuxBoot running on aarch64 uses mmap of /dev/mem to read the
smbios table. Linux's mapping of this memory doesn't allow the normal
unaligned fixup, so we get a bus error instead. We can't use the more
natural le16dec and friends because they optimize into a single,
unaligned memory load. We don't see this issue on aarch64 UEFI because
memory is mapped such that unaligned accesses are fixed up.

Clang 16 introduced a warning about single bit bitfields in structs,
which is triggered by a declaration in libsa's tftp.c:
stand/libsa/tftp.c:382:20: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion]

^ ~
Signed one-bit bitfields can only have values -1 and 0, but the intent
here is to use the field as a boolean, so make it unsigned.

When booting from a snapshot we need to follow a different code path
to turn the objset ID into the name, and for forward lookups we need
to walk the parent's snapnames_zap.
With this, it is possible to set the pools BOOTFS property to a
snapshot and boot with a read-only filesystem of that snapshot.

zfs lives in libsa. However, it depends on nvstore (and other things)
that are in common. Fix part of this layering violation by splitting
nvstore into a libsa piece (which is the base implementation) and
keeping a much smaller common piece (to implement the nvstore
command). This just leaves zfs' knowledge of device names that's
specific to common and its calling platform specific init code to
resolve. Add a nvstore.h file for these two parts to communicate private
things and move the public nvstore api from bootstrap.h to stand.h.

Since dev_cleanup() walks through all the devsw devices with dv_cleanup
rotuines, move it into libsa rather than having it in
'common'. Logically, it operates only on things that are in libsa, and
would never be different for different loaders: either people would call
it as is, or they'd do the loop themselves with 'special' things inline
between calls to cleanup (not that I think that will ever be needed
though).

It typically had two args with an optional third from the userland
declaration in sys/ioccom.h. However, the funciton definition used a
non-optional char * argument. This mismatch is UB behavior (but worked
due to the calling convetions of all our machines).
Instead, add a declaration for ioctl to stand.h, make the third arg
'void *' which is a better match to the ... declaration before. This
prevents the convert int * -> char * errors as well. Make the ioctl
user-space declaration truly user-space specific (omit it in the
stand-alone build).
No functional change intended.

On OpenFirmware, and possibly kboot, we use full path names for the
objects that are the 'device'. kboot uses a hack of knowing that all
disk device nodes start with '/dev', but this generalizes it for
OpenFirmware where both 'block' and 'network' devices live in the same
namespace and one must ask the OF node its type to know if this device
type matches.
For drivers that don't specify, the current convention of using
strncmp() is retained. This is done only in devparse(), but everything
uses it directly (or will soon).

To support more flexible device matching, we now pass in the full
devspec to the parsedev routines. For everything execpt uboot, this is
just a drop in (since everything except uboot and openfirmware always
uses disk...: and/or zfs:, but openfirmware isn't really affected).
uboot we kludge around it by subtracting 4 from where the rest of the
device name starts. This is unforunate, and can compute the address one
before the string. But we never dereference that address. uboot needs
more work, and this is an acceptable UB until that other work happens.
OFW doesn't really use the parsedev routines these days (since none of
the supported device uses this... yet). It too needs more work, but it
needs device matching support first.

Allow device classes to define a parsing routine. Most device classes
already have these routines, but there's much duplication in their
use. Define an interface for a common routine to parse an individual
device. By convetion, files have the form "[device:]/path/to/file"
where device is optional (filled in to be the value of currdev)
and it starts with the dv_name field of the device, with the rest
of the name up to the device (typically a unit number, but disks
add partition inforation, and other devices may do artibtrary
otehr things).

Change the first argument to zfs_parsedev() to be a pointer to a struct
devdesc *. This now gets filled in with a malloc'd structure that's
