I saw a situation where the driver set CAM_AUTOSNS_VALID on a failed ccb
even though SRB_STATUS_AUTOSENSE_VALID was not set in the status.
The actual sense data remained all zeros.
The problem seems to be that create_storvsc_request() always sets
hv_storvsc_request::sense_info_len, so checking for sense_info_len != 0
is not enough to determine if any auto-sense data is actually available.

This reverts commit eccd5a4d39.
According to comments in the Makefile, to make pxeboot work we need to
have crt0.o first. This is needed because the simplified loader in
pxeboot assumes that the startup code is at offset 0 in this binary. In
normal booting, the start address can be obtained from headers of the
binary, but since pxeboot encodes this as a pure binary, it has no way
of knowing where that is and assumes 0. Added comments to that effect
in the Makefile.
We've done this by adding it to OBJS before all the other .o's are
added. However, there's a problem. This also adds it to the CLEANFILES
variable, which causes it to be removed from multiple places. The
dependencies may also cause it to be re-built at a time that's after
boot2 is built. This causes installs to fail because at install time
boot2 is considered to be out of date and the programs to rebuild it are
no longer in the path.
Cope with this problem by just adding it to LDFLAGS instead.

Attaching and detaching devices can be heavy-weight and detaching can
sleep waiting for events. For that reason using the system-wide
single-threaded taskqueue_thread is not really appropriate.
There is even a possibility for a deadlock if taskqueue_thread is used
for detaching.
In fact, there is an easy to reproduce deadlock involving nvme, pass
and a sudden removal of an NVMe device.
A pass peripheral would not release a reference on an nvme sim until
pass_shutdown_kqueue() is executed via taskqueue_thread. But the
taskqueue's thread is blocked in nvme_detach() -> ... -> cam_sim_free()
because of the outstanding reference.

zfsd uses a device's physical path attribute to automatically replace a
missing ZFS disk when a blank disk is inserted into the same physical
slot. Currently gmultipath passes through its underlying providers'
physical path attribute. That may cause zfsd to replace a missing
gmultipath provider with a newly arrived, single-path disk. That would
be bad.
This commit fixes that problem by simply appending "/mp" to the
underlying providers' physical path, in a manner similar to what geli
already does.

Do not assume that the kernel boot time is invariant. It is not. FreeBSD
uses the formula:
wall_time = boot_time + uptime
where uptime is monotinically increasing and boot_time is adjusted to
get the proper time of day. FreeBSD offers a way to retrieve the uptime
directly, so use that instead of trying to compute it by subtracting
boot_time from wall_time.

In FreeBSD, the current time is computed from uptime + boottime. Uptime
is a continuous, smooth function that's monotonically increasing. To
effect changes to the current time, boottime is adjusted. boottime is
mutable and shouldn't be cached against future need. Document the
current implementation, with the caveat that we may stop stepping
boottime on resume in the future and will step uptime instead (noted in
