specifically, rewrite them to permit some markup in the column headers,
and use "Ta" instead of literal tabs; mandoc does not currently match groff
100%, but a mandoc fix may be some time off, and we've gone enough releases
with poorly formatting column lists.
in some cases i have rewritten the lists as -tag, where -column made
little sense.

.Bl -column header1 header2 ... <Bl flags>
mixing things up confuses mandoc, and adding flags in can screw up the list.
this hopefully just makes things a bit safer (and more consistent).
(one more bit of work left and all column lists should format how we want)

which is used by (amongst other things) initgroups(3) to set the supplemantary
groups on login.

Use bgpd(8) for this which on a peering router often needs openfiles-cur

smaller improvements; jmc@ and nicm@ both ask me to get this in because
further tweaking will be easier in-tree

dd_flags is renamed to the placeholder position dd_unused so that
we can spot "broken software" which assumes we have Jan Simon Pendry's
union mounts (we don't have them, and won't have them ever again).
