Remove unused library support for old-protocol responses other than FIOXY.

The non-deprecated library entry points can only send 'W' and 'R",
so library users can only see the responses that can occur in a 'W'
stream (FIOXY).  Thus, the code for the old single-shot responses
(ABCDEKMNPQSTUV) is dead and can be removed.

This change allows us to reclaim a client-side mask bit previously
used by the 'E' command.

Users were first warned against relying on these responses in 2005. Anybody
who had been using them since since was asking for trouble.
