By default only report unverified files at severity VE_WANT
and above. This inlcudes *.conf but not *.hints, *.cookie
or *.tgz which get VE_TRY as their severity.
If Verbose is set to 0, then VerifyFlags should default to 0 too.
Thus the combination of
module_verbose=0
VE_VEBOSE=0
is sufficient to make the loader almost totally silent.
When verify_prep has to find_manifest and it is verified ok
return VE_NOT_CHECKED to verify_file so that it can skip
repeating verify_fd
Also add better debugging output for is_verified and add_verify_status.
vectx handle compressed modules
When verifying a compressed module (.ko.gz or .ko.bz2)
stat() reports the size as -1 (unknown).
vectx_lseek needs to spot this during closing - and just read until
EOF is hit.
Note: because of the way libsa's open() works, verify_prep will see
the path to be verified as module.ko not module.ko.bz2 etc. This is
actually ok, because we need a separate module.ko.bz2 entry so that
the package can be verified, and the hash for module.ko is of the
uncompressed file which is what vectx will see.
Re-work local.trust.mk so site.trust.mk need only set
VE_SIGN_URL_LIST (if using the mentioned signing server)

The removal of the sparc64 support in February 2020 obsoleted the
VTOC8 partitioning scheme as no other FreeBSD platform makes use
of it. Moreover, the code is bitrotting as nothing defines e. g.
LOADER_VTOC8_SUPPORT any more and, thus, should go now, too. With
this change, the following commits are reverted as far as VTOC8
is concerned and parts haven't already previously been deleted
along with prior sparc64 removals:

The alignment example d9711c28ef

Address two issues with current help file logic:
The existing condition prevents the common help file from being
installed when there are no additional help files defined. This results
in no loader.help on EFI platforms, for example.
Second, due to the fact that we build and install multiple loader types,
each successive install will clobber the previous loader.help. The
result is that we could lose type-specific commands, or possibly list
them in loaders that do not have such commands.
Instead, give each loader type a uniquely named help file. The EFI
loader will look for /boot/loader.help.efi, userboot will look for
/boot/loader.help.userboot, etc. The interpreter variant has no effect
on which help file is loaded.
This leaves the old /boot/loader.help unused.
Some credit for the final approach goes to Mathieu <sigsys@gmail.com>
for their version of the fix in https://reviews.freebsd.org/D22951.

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.

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.

The existing logic doesn't seem to make much sense, as we won't filter
on the type if st_shndx != SHN_UNDEF. In practice, this breaks booting
12.3 kernels on newer loaders, as they do have a `kernphys` symbol of
the wrong type (NOTYPE, rather than OBJECT) -- we end up deriving the
wrong value for copy_staging.
It's unclear if this version makes any more sense, but it seems to match
what rtld's matched_symbol() does. Loader doesn't need to care about
STT_FUNC w/ UND shndx, because we won't encounter those; in kmods,
undefined (kernel) functions are NOTYPE.
