kern: osd: avoid dereferencing freed slots
If a slot is freed that isn't the last one, we'll set its destructor to
NULL to indicate that it's been freed and leave a hole in the slot map.
Check osd_destructors in osd_call() to avoid dereferencing a method that
is potentially from a module that's been unloaded.
This scenario would most commonly surface when two modules are loaded
that osd_register(), then the earlier one deregisters and an osd_call()
is made after the fact. In the specific report that triggered the
investigation, kldload if_wg -> kldload linux* -> kldunload if_wg ->
destroy a jail -> panic.
Noted in the review, but left for follow-up work, is that the realloc

libc: fix some overflow scenarios in vis(3)
The previous incarnation of this would call wcrtomb() on the destination
buffer, and only check for overflow *after* it's happened.
Additionally, the conversion error / VIS_NOLOCALE path also didn't check
for overflow, and the overflow check at the end didn't account for the
fact that we still need to write a NUL terminator afterward.
Start by only doing the multibyte conversion into mbdst directly if we
have enough buffer space to guarantee it'll fit. An additional
MB_CUR_MAX buffer has been stashed on the stack to write into if we're
cutting it close at the end of the buffer, since we don't really have a
good way to determine the length of the wchar_t without just doing the
conversion. We'll do the conversion into the buffer that's guaranteed
to fit, then copy it over if the copy won't overflow.
The byte-for-byte overflow is a little bit easier, as we simply check
for overflow with each byte written and make sure we can still NUL
terminate after.

Handle UFS/FFS file deletion from cylinder groups with check-hash failure.
When a file is deleted, its blocks need to be put back in the free
block list and its inode needs to be put back in the inode free list.
These lists reside in cylinder-group maps. If either some of its blocks
or its inode reside in a cylinder-group map with a bad check hash
it is not possible to free the associated resource. Since the cylinder
group cannot be repaired until the filesystem is unmounted these
resources cannot be freed. They simply accumulate in memory. And
any attempt to unmount the filesystem loops forever trying to flush them.
With this change, the resource update claims to succeed so that the
file deletion can successfully complete. The filesystem is marked as
requiring an fsck so that before the next time that the filesystem is
mounted, the offending cylinder groups are reconstructed causing the
lost resources to be reclaimed.
A better solution would be to downgrade the filesystem to read-only,
but that capability is not currently implemented.
