Inject \e[J to erase the initial loader screen. We have two options,
find where out cursor is and use BIOS scroll for data from boot2 or erase the
display and start from origin. Erasing the screen is easier and we also
get the screen buffer initialized.

The arguments for VFS_CHECKEXP() were changed by r362158.
Also, the numsecflavors and secflavors arguments were not documented,
so add these as well.
This is a content change.
Previously, it used atoi(3) to parse the unit parameter, which would silently
yield a unit of 0 in the presence of an invalid unit number. As most users of
mpsutil(8) are likely to have at least a unit 0, this is could have confusing
results.
This behaviour was particularly unintuitive if one incorrectly passed an
adapter device name, or a device path, instead of a unit number. In addition
to using strtoumax(3) instead of atoi(3) to parse unit numbers, support
stripping a device name (e.g. mps1) or path (e.g. /dev/mps2) to just its unit
number.

Compiling on a RISC-V system fails with 'relocation R_RISCV_ALIGN
requires unimplemented linker relaxation; recompile with -mno-relax'.
Our default linker (ld.lld) doesn't support relaxation, so default to
no-relax so we don't generate object files the linker can't handle.

packet drill script was failing with a number of unexpected acks. So it turns
out if you have the default recvwin set up to 1Meg (like OCA's do) and you
have no window scaling (like the dupack checking code) then we have another
case where we are always trying to update the rwnd and sending an
ack when we should not.

Currently newsyslog supports <include> directive that is used
in our default /etc/newsyslog.conf in the following form:
<include> /usr/local/etc/newsyslog.conf.d/*
While this is suitable for ports installing their own rules
for logs rotation, this also makes newsyslog break entire
processing of all files if it encounters single line it cannot parse.
This includes lines referring to nonexistent username/group for log
ownership, so newsyslog stops calling errx() function in the parser.
With this fix, newsyslog uses warnx() instead of errx() in such cases
to print a warning, recover gracefully and continue with execution.
Among other cases, this unbreaks initial creation of log files
having flag "C" at boot time (newsyslog -CN). This is most important
for systems having RAM-based /var file system like nanobsd(8)-based
that rely on newsyslog to bring system log files into existence.

This patch moves the UID_xxx and GID_xxx definitions out of the
#ifdef _KERNEL section, so that userspace programs like mountd
can use them.
There are a couple of userspace programs that do define UID_ROOT,
but they do not include sys/conf.h. Since they are defined as
the same value, maybe they should be changed to include sys/conf.h.

U-APSD (unscheduled automatic power save delivery) is a power save method
that's a bit better than legacy PS-POLL - stations can mark frames with
an extra flag that tells the AP to leak out more frames after it sends
its own frames rather than needing to send a PS-POLL to get another frame
from the AP.
Now, this code just handles the negotiation bits; it doesn't actually
implement U-APSD. That's up to drivers, and nothing in the tree yet
implements this. I /may/ implement this for ath(4) if I eventually care
enough but right now I plan on just implementing it for firmware offload
based NICs that handle this in the NIC.
I'll commit the ifconfig bit after this and I may have some follow-up
commits as this gets used more by me in local testing.
This should be a glorious no-op for everyone else. If things change
for anyone that isn't fixed by a complete recompile then please reach out
to me.

Since the two functions are similar, introduce a common function
(vtnet_rx_vq_process()) to share common code.
This also improves locking, by ensuring vrxs_rescheduled is accessed
under the RXQ lock, and taskqueue_enqueue() is not called under the
lock (therefore avoiding a spurious duplicate lock warning).
