These are all in POSIX now. ENORECOVERABLE and EOWNERDEAD are errors
returned for robus mutexes that we don't implement yet (but might want
to implement at one point). EBASMSG and EPROTO are really obsolete
values for streams. EBADMSG got re-used in catgets(3), but our
implementation doesn't generate it and the message passing extension
(which we don't implement). EPROTO probably should have been marked
as obsolete (and therefore optional). Given that Darwin, FreeBSD,
NetBSD, Linux and Solaris all provide this, we're probably better off
adding them as well.
