When a function not returning RECORD has a single OUT parameter, use

When a function not returning RECORD has a single OUT parameter, use
the parameter's name (if any) as the default column name for SELECT FROM
the function, rather than the function name as previously.  I still think
this is a bad idea, but I lost the argument.  Force decompilation of
function RTEs to specify full aliases always, to reduce the odds of this
decision breaking dumped views.
