This gets rid of the last BSD-4-clause licensed file in the project.
The man page will probably need to be adapted to the current
implementation, but that can be done piecemeal afterwards.
Closes: #7
The versions used in the BSD macros are unknown, so they emit warnings,
extend or reduce them to use the two digit form. Correct the glibc
version when closefrom(3) got introduced.
This function cannot be easily and (more importantly) correctly ported
without cooperation from the libc stdio layer. We already document that
users should be prepared to have the function not available on some
platforms and that they should ideally switch their code to other
more portable and better interfaces.
Instead of making the build fail, and requiring porters to add
exceptions for something that most probably cannot be ported correctly
anyway, simply print a warning and let it build. This will not be a
regression because on those systems libbsd would have never been built
before.

This means we can add a trailing «\» to every element, so that they
can be removed without requiring modification of other lines, and can
be easily sorted.
Replace the old usage of $(nil) which could possibly end up with junk
added if such variable is ever defined, in the environment.
This makes code using it non-portable, and requires the namespeced
headers from libbsd, instead of any generic system headers. It also
requires more code changes than the overlay mode.
The former used to be the reference implementation, but it has been
stagnant to the point of not showing much signs of life. Switch to
the currently active and more complete implementation for references.
While using fully uppercase man page titles has been the usual
convention for a very long time, it is rather ugly and something that
some other projects are switching away from.
This brings <sys/queue.h> to the most up-to-date version from FreeBSD,
incorporating 18 commits from the past 5 years (2015-02-24 - 2021-01-25):
$ git log --oneline 9090a24aed70..8d55837dc133 sys/sys/queue.h share/man/man3/queue.3
Only minimal changes compared to the FreeBSD version have been applied
(queue.3 -> queue.3bsd, _LIBBSD_ prefix).

This splits the implementation responsibilities, and reduces embedded
code copies, which was one of the driving points with this project to
start with, so it's nice to give a good example.
Add recallocarray(), introduced in OpenBSD 6.1, and freezero(),
introduced in OpenBSD 6.2. The former is imported as-is from OpenBSD,
while the latter is the non-malloc-internal branch of the same code (and
also the OpenSSH portable variant).
Both of these originated in OpenBSD, but have also been implemented by
IllumOS, cf. https://www.illumos.org/issues/8546
Documentation for these functions is in malloc(3) upstream, the relevant
parts of which were previously imported in reallocarray(3bsd). Update
reallocarray(3bsd) with the changes that were introduced since, and add
the relevant bits for recallocarray() and freezero(), plus aliases.

Even though man-pages project now includes man pages for system data
types, we still include these for any other system that does not have
them, to provide a self-contained project with code and documentation.
groff(1) has changed the internal layout for the .Lb doc strings, but to
preserve backwards compatibility we cannot simply rename them, we need
to create new aliases so that these will work with old and new macros.

Use EINVAL instead of EDOOFUS. Add a missing synopsis for
pidfile_fileno() in the man page. Move the definition of struct pidfh
from libutil.h into pidfile.c following upstream change.
We mention that these are now superseded by the glibc implementations,
make the headers cope with already declared functions on glibc-based
systems, and document this in the man pages.
We have moved all man pages to section 3bsd, let's do the same for the
page title, and in all the references for uniformity and to avoid
confusions.
