9fd4b8ffab Fix build with src on a noexec filesystem.
${SH} expands to nothing on src builds so this worked by accident.  Use

Arguably the entire -p option should be removed.  It shows only a few

07ca59522d Check in the generated copies of the manpages
These manpages were meant to be templated once per `configure` run.

Given that we're not bound by as many constants, e.g., `--prefix` isn't
generally changing for kyua in the base system, having to generate the
manpages each build seems slightly less than optimal.

In the event that one's build environment doesn't define `$SH`, the build
will also fail until this change is introduced.

Instead of jumping through hoops dealing with shells or permissions, let's
just cut to the chase and check the generated copies into the sourcebase
under usr.bin/kyua .

c0f2b64a89 Use -F instead of -f in tail(1) examples
There is an example in tail(1) manual page explaining how to use tail(1) to
track the contents of /var/log/messages. The example uses the -f flag to
follow the file. The problem with the -f flag is that it cannot handle the
situation where /var/log/messages is rotated. Hence, use -F instead in the
example.

3431172fa8 Tell the world how to convert gigabytes to bytes with units(1) easily
It turns out that units(1) is not as horrible to use in scripts
as I initially thought. When the --terse flag is combined
with an appropriate output format (set via --output-format),
units(1) is actually capable of producing very nice results.
For example:

    units -o %0.f -t '4 gigabytes' bytes

is is just going to print out the expected value of 4294967296.

There is no time to waste. People have to know about it.

I am adding an example for this at the top of the examples section
because this is what users are most likely looking for.

a0eb385c2e Remove unneeded checks for prelen.
In order to determine the type of a compressed file, we have to read
in the first four bytes which may also be important for decompression
purposes, to do that we would pass the buffer that we have already
read in, along with the size of it.

Rename header1 to fourbytes to make that explicit, and remove all
checks for prelen.

134b378392 retire in-tree GPL dtc devicetree compiler
Now that we no longer have GCC 4.2.1 in the tree and can assume FreeBSD
is being built with a C++11 compiler available, we can use BSDL dtc
unconditionally and retire the GPL dtc.

GPL dtc now has FreeBSD CI support via Cirrus-CI to help ensure it
continues to build/work on FreeBSD and is available in the ports tree
if needed.

The copy of (copyfree licensed) libfdt that we actually use is in
sys/contrib/libfdt so the extra copy under contrib/dtc/libfdt can be
removed along with the rest of the GPL dtc.

57f804675e remove GCC 4.2.1 build infrastructure
As described in Warner's email message[1] to the FreeBSD-arch mailing
list we have reached GCC 4.2.1's retirement date.  At this time all
supported architectures either use in-tree Clang, or rely on external
toolchain (i.e., a contemporary GCC version from ports).

GCC 4.2.1 was released July 18, 2007 and was imported into FreeBSD later
that year, in r171825.  GCC has served us well, but version 4.2.1 is
obsolete and not used by default on any architecture in FreeBSD.  It
does not support modern C and does not support arm64 or RISC-V.

Thanks to everyone responsible for maintaining, updating, and testing
GCC in the FreeBSD base system over the years.

So long, and thanks for all the fish.

0573d0a9b8 vfs: add realpathat syscall
realpath(3) is used a lot e.g., by clang and is a major source of getcwd
and fstatat calls. This can be done more efficiently in the kernel.

This works by performing a regular lookup while saving the name and found
parent directory. If the terminal vnode is a directory we can resolve it using
usual means. Otherwise we can use the name saved by lookup and resolve the
parent.

See the review for sample syscall counts.
