Extend the net backend interface with two functions, namely netbe_rx_disable()
and netbe_rx_enable(), which can be used by the net device emulators to stop
the backend from invoking the receive callback. This is useful for device
emulators, i.e., on hardware resets or to implement receive backpressure.
The mevent module has been extendede to support the addition of a disabled
event. To prevent race conditions, the net backends will start with receive
operation disabled. A follow-up patch will use the new functionalities in
the virtio-net device.

This commit adds two new extensions to crontab, ported from OpenBSD:
- -n: suppress mail on succesful run
- -q: suppress logging of command execution
The -q option appears decades old, but -n is relatively new. The
original proposal by Job Snijder can be found here [1], and gives very
convincing reasons for inclusion in base.
This patch is a nearly identical port of OpenBSD cron for -q and -n
features. It is written to follow existing conventions and style of the
existing codebase.
Example usage:
# should only send email, but won't show up in log
* * * * * -q date
# should not send email
* * * * * -n date
# should not send email or log
* * * * * -n -q date
# should send email because of ping failure
* * * * * -n -q ping -c 1 5.5.5.5

`freebsd-update updatesready' can be used to check if there are any pending
fetched updates that can be installed.
`freebsd-update showconfig' writes freebsd-update's configuration to
stdout.
This also changes the exit code of `freebsd-update install' to 2 in case
there are no updates pending to be installed and there wasn't a fetch phase
in the same invocation. This allows scripts to tell apart these error
conditions without breaking existing jail managers.
See freebsd-update(8) for details.

message:
On non-x86 systems, use "quarterly" packages.
x86 architectures have "latest" package builds on stable/*, so keep using
those (they'll get switched over to "quarterly" during releases).
The original commit was a direct commit to stable/12, as at the time it
was presumed it would not be necessary for head. However, when it is time
to create a releng branch or switch from PRERELEASE/STABLE to BETA/RC, the
pkg(7) Makefile needs further adjusting. This commit includes those
further adjustments, evaluating the BRANCH variable from release/Makefile
to determine the pkg(7) repository to use.

With newer import of libedit, the path to be able to access readline/readline.h
will also include header which name will conflict with some expected by ntp in
another path and end up breaking the build.
Setting the B_INVALONERR flag before a synchronous write causes the buf
cache to forcibly invalidate contents if the write fails (BIO_ERROR).
This is intended to be used to allow layers above the buffer cache to make
more informed decisions about when discarding dirty buffers without
successful write is acceptable.
As a proof of concept, use in msdosfs to handle failures to mark the on-disk
'dirty' bit during rw mount or ro->rw update.
Extending this to other filesystems is left as future work.

This code has been written as a proof of concept, but I think that it
can be useful in general. It allows to set the status of an enclosure
slot. Practically, this means controlling whatever slot status LEDs the
enclosure provides. At present, the new command does not have sanity
checks or any conveniences. That means that it is possible to issue the
command for an invalid slot and an enclosure. But the worst I have seen
happening is either the command failing or simply being ignored. Also,
at the moment, the status has to be specified as a numeric bit mask.
The bit definitions can be found in sys/dev/mps/mpi/mpi2_init.h, they
are prefixed with MPI2_SEP_REQ_SLOTSTATUS_. The only way to address a
slot is by the enclosure handle and the slot number. Both are readily
available from mpsutil show commands.
So, future enhancements could include alternative ways to address a slot
(e.g., by a disk handle or a disk device name) and human friendly names
for slot statuses.
The new command is useful alternative to 'sas2ircu locate' command.
First, sas2ircu is a proprietary blob. Second, it supports setting only
locate / identify status bit.

Revision 316342, which introduced the anticongestion feature, failed to
consider that the periodic scripts are executed by a recursive invocation of
periodic. The recursive invocation wrongly cleaned up a temporary file that
should've been cleaned up only by the original invocation. The result is
that if the first script that requests an anticongestion sleep runs after
the security scripts, the sleep won't happen.
Fix this bug by delaying cleanup until the end of the original invocation.
