It does extremely useful things like execute sendmail and spew dubiously

From the feedback, it seems like it is an essential utility in a modern unix

Reverts r358561.
With powerd_flags="-N", this makes powerd(8) exclude "nice" time when
computing the CPU utilization. This makes it possible to prevent
CPU-intensive "background" processes from spinning up the CPU.
Note that only *userland* CPU usage belonging to "nice" processes is
excluded; we do not track whether time spent in the kernel is on behalf
of nice or non-nice processes, so kernel-intensive nice processes can
still result in the CPU being sped up.

This is the result of splitting r358153 in two, in order to avoid a build
system bug and being able to merge the change to previous releases..
Document better this file, updating the URL to the IANA registry and closely
match the official services.
For system ports (0 to 1023) we now try to follow the registry closely, noting
some historical differences where applicable.
As a side effect: drop references to unofficial Kerberos IV which was EOL'ed
on Oct 2006[1]. While it is conceivable some people may still use it in some
very old FreeBSD machines that can't be replaced easily, the use of it is
considered a security risk. Also drop the unofficial netatalk, which we
supported long ago in the kernel but was dropped long ago.
Leave for now smtps, even though it conflicts with IANA's submissions.
The change should have very little visibility, if any, but should be a
step closer to the current IANA database.

Give up the battle to keep extra files in $MACHINE/compile to keep the file in
the tree. Instead, create CDIR (usually ../compile) if it doesn't exist when
we're using a default build location (eg, not using -d). If it does, we do
nothing. This only affects people that do old-school builds, but it's bit me a
dozen times since last summer so time to fix the bug.
This change reflects the ability to change machine_arch in a config file. This
is useful for including one config in another and changing the machine_arch
in the second one.
Currently, you can have multiple machine directives if they are otherwise
identical. Relax this so that only the machinename part is the same. This allows
one to change the machine arch in a different config file you've included easily.
Currently, the size of the swap device is unconditionally reported using
blocks, even if -h has been used.
- While here, switch to CONVERT_BLOCKS() instead of CONVERT() which will
avoid overflowing size counters (in human readable form see: r196244)
- Update the column headers to reflect that a size is being reported instead
of the block size units being used

This patch adds a new netbe_peek_recvlen() function to the net
backend API. The new function allows the virtio-net receive code
to know in advance how many virtio descriptors chains will be
needed to receive the next packet. As a result, the implementation
of the virtio-net mergeable rx buffers feature becomes efficient,
so that we can enable it also with the tap(4) backend. For the
tap(4) backend, a bounce buffer is introduced to implement the
peeck_recvlen() callback, which implies an additional packet copy
on the receive datapath. In the future, it should be possible to
remove the bounce buffer (and so the additional copy), by
obtaining the length of the next packet from kevent data.

ACPI Control Method Batteries have a _BIF and/or _BIX object which
provide static properties of the battery. FreeBSD acpi_cmbat module
supported _BIF object only, which was deprecated as of ACPI 4.0.
_BIX is an extended version of _BIF defined in ACPI 4.0 or later.
As of writing, _BIX has two revisions. One is in ACPI 4.0 (rev.0) and
another is in ACPI 6.0 (rev.1). It seems that hardware vendors still
stick to _BIF only or _BIX rev.0 + _BIF for the maximum compatibility.
Microsoft requires _BIX rev.0 for Windows machines, so there are some
laptop machines with _BIX rev.0 only. In this case, FreeBSD does not
recognize the battery information.
After this change, the acpi_cmbat module gets battery information from
_BIX or _BIF object and internally uses _BIX rev.1 data structure as
the primary information store in the kernel. ACPIIO_BATT_GET_BI[FX]
returns an acpi_bi[fx] structure built by using information obtained
from a _BIF or a _BIX object found on the system. The revision number
field can be used to check which field is available. The acpiconf(8)
utility will show additional information if _BIX is available.
Although ABIs of ACPIIO_BATT_* were changed, the existing APIs for
userland utilities are not changed and the backward-compatible ABIs
are provided. This means that older versions of acpiconf(8) can also
work with the new kernel. The (union acpi_battery_ioctl_arg) was
padded to 256 byte long to avoid another ABI change in the future.
A _BIX object with its revision number >1 will be treated as
compatible with the rev.1 _BIX format.

In order to do so we need to install the msdosfs headers to the bootstrap
sysroot and avoid includes of kernel headers that may not exist on every

on FreeBSD 11+ as well as Linux and macOS.
We also have to avoid using the IO_SYNC macro since that may not be
available. In makefs it is only used to switch between calling
bwrite() and bdwrite() which both call the same function. Therefore we
can simply always call bwrite().
For our CheriBSD builds we always bootstrap makefs by setting

command line option. Thanks to the removal of unnecessary information and
the organization into columns, this helps the output be more legible on
both 80 column displays and non-80 column displays. imp@ provided the
idea on this.
Highlights:
- Use MAX() for maxsock raising; small readability improvement IMO
- malloc(3) + memset(3) -> calloc(3) where appropriate
- stop casting the return value of malloc(3)
- mallloc(3) -> reallocarray(3) where appropriate
A future change may enter capability mode when forking for some of the
built-in handlers.
This change is purely in the name of noise reduction from static analyzers
that want to complain that bzero(3) is obsolete in favor of memset(3).
With this, clang-analyze at least is now noise free. WARNS= 6 also appears
to have been OK for some time now, so drop the current setting and opt for
the default.
Currently, child pids are only tracked if maxchildren is specified. As a
consequence, without a maxchild limit we do not get a notice in syslog on
children aborting abnormally. This turns out to be a great debugging aide at
times.
Children are now tracked in a LIST; the management interface is decidedly
less painful when there's no upper bound on the number of entries we may
have at the cost of one small allocation per connection.

The main point here is capturing the maxchild > 0 check. A future change to
inetd will start tracking all of the child pids so that it can give proper
and consistent notification of process exit/signalling.
