Anyway, I'm not sure about this.  connect_port is already a pretty
stupid unnecessarily-expensive mechanism that should probably die
outright, and globally speaking, here we're trading float comparison
for an indirect function call.  That's probably a win for a huge number
of control ports, but it seems like a pretty onerous requirement to
expect from hosts in general.  Lots of hosts simply call connect_port
unconditionally every period for some things because doing otherwise is
a pain.

connect_port adds a bunch of statefulness to the API that both sides
need to deal with and doesn't need to be there at all.  Easily the
worst thing in LADSPA that I really wish we hadn't inherited...

That said, this idea is clear enough, and simply a feature description,
so I'm not opposed to adding it.
