docs: Regenerate man pages with a newer version of pod2man

The manpages are generated from pod files using pod2man, but it has been
a long time since we last re-generated them, and the new versions of
pod2man generate significantly different (and simpler) pages.

So this patch just regenerates the man pages, to make future changes
easier and more self contained to review.
