Log message:
    Add optional "validator" function to languages that can validate the
    function body (and other properties) as a function in the language
    is created.  This generalizes ad hoc code that already existed for
    the built-in languages.

    The validation now happens after the pg_proc tuple of the new function
    is created, so it is possible to define recursive SQL functions.

    Add some regression test cases that cover bogus function definition
    attempts.
