mdoc: move CAVEATS, BUGS and SECURITY CONSIDERATIONS sections to the
bottom of the manpages and order them consistently.

GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

Write timestamps with exactly 9 digits after the period.
This ensures that the value written is both compatible with
older mtree versions (which expect the value after the period
to be an integer count of nanoseconds after the whole second)
and is a correct floating-point value.

Leave the parsing code unchanged so it will continue to read
older files.

Add the mtree.5 manpage. I'll come back soon and
remove the format specification from mtree.8.
I also need to reconcile a few issues between this
mtree.5 and what is actually implemented in FreeBSD's
mtree utility.
