MFC r272308: Fix old iSCSI initiator to work with new CAM locking.
This switches code to using xpt_rescan() routine, irrelevant to locking.
Using xpt_action() directly requires knowledge about higher level locks,
that SIM does not need to have.
This code is obsolete, but that is not a reason to crash.

Allow the PIC's IMR register to be read before ICW initialisation.
As of git submit e179f6914152eca9, the Linux kernel does a simple
probe of the PIC by writing a pattern to the IMR and then reading it
back, prior to the init sequence of ICW words.
The bhyve PIC emulation wasn't allowing the IMR to be read until
the ICW sequence was complete. This limitation isn't required so
relax the test.

on boot when calibrating the local APIC.

rm -rf can fail sometimes with an error from fts_read. Make it
honor fflag to ignore fts_read errors, but stop deleting from
that directory because no further progress can be made.
When building a kernel with a high -j value on a high core count
machine, during the cleanobj phase we can wind up doing multiple
rm -rf at the same time for modules that have subdirectories. This
exposed this race (sometimes) as fts_read can return an error if
the directory is removed by another rm -rf. Since the intent of
the -f flag was to ignore errors, even if this was a bug in
fts_read, we should ignore the error like we've been instructed
to do.

Correct display of bhyve SMBIOS UUIDs with dmidecode by bumping the version.
The mixed little/big-endianness of SMBIOS UUIDs was clarified in v2.6
of the SMBIOS spec. dmidecode uses the reported version of SMBIOS to
determine the layout and what to byte-swap.
bhyve's SMBIOS reported as 2.4 though it implemented the 2.6-style of
memory layout. This resulted in dmidecode reporting a different
UUID than one passed in via the -U option.
Iterate through all the children instead of returning error when we hit
the first error. This makes the error message give more information
rather than just the first device that causes problem.
Illumos issue:
5118 When verifying or creating a storage pool, error messages only
show one device
When asked to find a hole, the DMU sees that there are no holes in the
object, and returns ESRCH. The ZPL interprets this as "no holes before
the end of the file", and therefore inserts the "virtual hole" at the
end of the file. Because DMU and ZPL have different ideas of where the
end of an object/file is, we will end up returning the end of file,
which is generally larger, instead of returning the end of object.
The fix is to handle the "virtual hole" in the DMU. If no hole is found,
the DMU will return a hole at the end of the file, rather than an error.
Illumos issue:
5139 SEEK_HOLE failed to report a hole at end of file
Make it possible to use empty user name ("-U ''") for mount_smbfs(8).
It's just like "-U guest", except that it actually works, at least
with Samba 4, which seems to return authentication failure for "-U guest".
