If virtio_setup_intr() failed during boot, we would hang in
taskqueue_free() -> taskqueue_terminate() for all the taskq
threads to terminate. This will never happen since the
scheduler is not running by this point.

Rather than trying to KASSERT for callers that invoke this on
IO tags, either do nothing (for write_8) or return ~0 (for read_8).
Using KASSERT here just makes bus.h too messy from both
polluting bus.h with systm.h (for any number of drivers that include
bus.h without first including systm.h) or ports that use bus.h
directly (i.e. libpciaccess) as reported by zeising@.
Also don't try to implement all of the other bus_space functions for
8 byte access since realistically only these two are needed for some
devices that expose 64-bit memory-mapped registers.
Put the amd64-specific functions here rather than sys/amd64/include/bus.h
so that we can keep this header unified for x86, as requested by mdf@
and tijl@.

making range consolidation much more effective particularly for small
deletes.
This reduces memory used by the free map as well as reducing the number
of bio requests down to geom required to process all deletes.
In tests this achieved a factor of 10 reduction of trim ranges / geom
call downs.
While I'm here correct the description of zio_vdev_io_start.

this also firms up some of the input parsing so it handles short frames a
bit better.
This actually fixes reading beyond mbuf data area in pfsync_input(), that
may happen at certain pfsync datagrams.

Prior to r222417, setting `password' in loader.conf(5) did not prevent boot
but instead only prevented changes to boot options by prompting for password
if autoboot failed or the user interrupted the countdown sequence.
After r222417 the same machine with `password' set in loader.conf(5) would no
longer boot without _always_ entering the password.
This patch restores the old (8.x and older) functionality for password in
loader.conf(5) while adding a new bootlock_password feature to replace the
edge-case should anybody desire the regressed functionality (HINT: great for
PXE servers and/or private distributions).
loader.conf(5) was updated to be more clear with-respect to password setting
(previous text was misleading).
Documentation (loader.conf(5) and check-password.4th(8)) has been updated to
include notes on the new bootlock_password setting.
Special thanks to Alex Verbod for bringing this to my attention and helping to
refine the loader.conf(5) text.

Add the following flags to sysctl:
-W - show only writable sysctls
-T - show only tuneable sysctls
This can be used to create a /var/run/sysctl.boot to
compare set tunables versus booted tunables.
