Some refactoring to export json(b) conversion functions

Browse Source 
This is to export datum_to_json(), datum_to_jsonb(), and
jsonb_from_cstring(), though the last one is exported as
jsonb_from_text().

A subsequent commit to add new SQL/JSON constructor functions will
need them for calling from the executor.
