Here's a rework of this patch. It preserves the original signature of 
to_json{b}_is_immutable, and fixes some code duplication. It also uses 
the typecache to get composite info instead of calling relation_open, 
supports MultiRange types, and exits early if we made a recursive call 
(no need for json_categorize_type etc. in these cases).
