Fix grammar for IN/OUT/INOUT parameters. This commit doesn't actually
implement any new feature, it just pushes the 'not implemented' error
message deeper into the backend. I also tweaked the grammar to accept
Oracle-ish parameter syntax (parameter name first), as well as the
SQL99 standard syntax (parameter mode first), since it was easy and
people will doubtless try to use both anyway.
