qio: Clean up q.*full()

The old qfull() and qwritable() should be opposites.  qfull() was actually
wrong in that if we had set no limit, qfull() would always return TRUE
instead of always returning FALSE.  I guess in Plan 9 it was on the caller
to know if there was a limit or not.

qnotfull() was a rendez condition, not a generic function.  It also wasn't
just about being full or not, it included being closed.  Renaming the
function makes that more clear.
