Here is a first try.  I did pretty much exactly what I proposed in the
quoted text, so I don't have much else to say about it.  I didn't see an
easy way to specify multiple ids and xreflabels for a given entry, so the
entries that describe multiple roles just use the name of the first role
listed.  In practice, I think this just means you need to do a little extra
work when linking to one of the other roles from elsewhere in the docs,
which doesn't seem too terrible.
