Rename gen_marshal_input() to gen_marshal(), because the generated
function marshals both arguments and results.
Rename gen_visitor_input_containers_decl() to gen_marshal_vars(), and
move the other variable declarations there, too.
Rename gen_visitor_input_block() to gen_marshal_input_visit(), and
rearrange its code slightly.
Rename gen_marshal_input_decl() to gen_marshal_proto(), because the
result isn't a full declaration, unlike gen_command_decl()'s.
New gen_marshal_decl() actually returns a full declaration.
