Peter Eisentraut 8ce795fcb7 Fix some confusing uses of const
There are a few places where we have

    typedef struct FooData { ... } FooData;
    typedef FooData *Foo;

and then function declarations with

    bar(const Foo x)

which isn't incorrect but probably meant

    bar(const FooData *x)

meaning that the thing x points to is immutable, not x itself.

This patch makes those changes where appropriate.  In one
case (execGrouping.c), the thing being pointed to was not immutable,
so in that case remove the const altogether, to avoid further
confusion.
