mdoc: make pages render with mandoc

It's a bit more pedantic regarding .Bl list elements. This has an added
benefit of unbreaking the ipfw(8) manpage, where groff was silently
skipping one list element.

Sort sections.

Added the EXIT STATUS section where appropriate.

Introduce options definition the standard way.

Give an example showing how to change the mesg status of terminals
other than the default one.

PR: 13073

Affect the first of stdin, stdout and stderr that is attached to a terminal.
Write status information to stdout instead of stderr.
Exit status when an error occurs musn't be 1, that is reserved for
indicating that messages are disabled.

These changes bring mesg(1) up to SUSv3 conformance.
