I pushed the first two commits (the selinux stuff) and worked a bit more on
the subsequent ones.

- As requested, I've renamed the 'doc-html' and 'doc-man' targets to just 'html'
and 'man'. Which then seems to also necessitates renaming the existing
install-doc-{html,man}. I'm not so sure about this change, likely because I
use autocomplete to remember the spelling of ninja (or make) targets, which
is easier with [install-]doc-{html,man} than with [install-]{html,man}.

- I added a commit to change what 'docs' builds, undoing that part of
969509c3f2e. I also moved the 'all' target in doc/src/sgml/Makefile up to
the 'html' target to make things less confusing there, as discussed in the
thread referenced in the commit message.

Because of the 'html' target, Tom can still just build html easily.

- I renamed 'meson-targets.txt' to 'targets-meson.txt' and renamed other files
to match. One reason is that meson tries to prevent conflict between its
internal targets by prefixing them with 'meson-', and the old names
conflicted with that rule. If we ever wanted to add something similar for
make, the new naming also seems better.

- I added documentation for some developer targets (reformat-dat-files,
expand-dat-files, update-unicode)

I didn't move 'world' in the docs, as it doesn't quite seem right in the "code
targets" section?

I attached the pkglibdir thing again, even though I don't plan to push it or
really review it further. Thought it might still be interesting for Christoph.
