If there is a write error on stdout, a message will be printed (to stderr)
and the exit status will be changed to 2 if it would have been 0 or 1.

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.

This gives us the flexibility needed when shipping images to a

In preparation for sysctl(8) growing the ability to only print
out boot/run-time tunables we need a way to differentiate between
RW sysctl nodes that tune a particular thing, or simply export
a stat that we want to allow the sysadmin to reset to 0 (or some
other value).
To do so, we add the CTLFLAG_STATS which should be OR'd into the
CTLFLAGs when exporting a "writable/resettable" statistic node via
sysctl.
kern_yield() is problematic than.
The owned mutex is the mount interlock, and it is in fact not needed
to guarantee the stability of the mount list of active vnodes, so fix
the the issue by only taking the mount interlock for MNT_REF and
MNT_REL operations.
While there, augment the unconditional yield by some amount of
spinning [1].

Add a flag to the bpf descriptor to indicate whether the hold buffer
is in use. In bpfread(), set the "hold buffer in use" flag before
dropping the descriptor lock during the call to bpf_uiomove().
Everywhere else the hold buffer is used or changed, wait while
the hold buffer is in use by bpfread(). Add a KASSERT in bpfread()
after re-acquiring the descriptor lock to assist uncovering any
additional hold buffer races.
