These lines are generally out-of-date, incomplete and unnecessary. With
SPDX and git repository much more accurate and fine grained information
about licensing and authorship is available, hence let's drop the
per-file copyright notice. Of course, removing copyright lines of others
is problematic, hence this commit only removes my own lines and leaves
all others untouched. It might be nicer if sooner or later those could
go away too, making git the only and accurate source of authorship
information.

This part of the copyright blurb stems from the GPL use recommendations:
https://www.gnu.org/licenses/gpl-howto.en.html
The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.
hence, let's just get rid of this old cruft, and shorten our codebase a
bit.

This new helper combines asprintf() and write_string_file() in one,
which is useful at various places to shorten the code a bit.

This changes
r = ...;
if (r < 0)
to
if (... < 0)
when r will not be used again.

Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.
I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

This new function reports whether ambient caps are available, and should
be quick because the result is cached.

privileges when executing a NOP
This way daemons which already dropped all caps may use the call to
drop priviliges again, which becomes a non-failing NOP.

Let's drop the caching of the setgroups /proc field for now. While there's a
strict regime in place when it changes states, let's better not cache it since
we cannot really be sure we follow that regime correctly.
More importantly however, this is not in performance sensitive code, and
there's no indication the cache is really beneficial, hence let's drop the
caching and make things a bit simpler.
Also, while we are at it, rework the error handling a bit, and always return
negative errno-style error codes, following our usual coding style. This has
the benefit that we can sensible hanld read_one_line_file() errors, without
having to updat errno explicitly.

It might be blocked through /proc/PID/setgroups

This is a cleaned up result of running iwyu but without forward
declarations on src/basic.

Although having a two line mask like
/// UNNEEDED by elogind
#if 0
it is much more easier to read (and patch!) if those two lines were
condense into a one-line mask start like
#if 0 /// UNNEEDED by elogind

The util.[hc] files have been stripped of a lot of functions, that
got sorted into various new files representing the type of
utility.
This commit adds the missing files.
