STO APIs

APIs for parsing and manipulating serialized transaction objects (STOs) — locating a field or array element by code, and inserting or removing a field to build a new object. These functions used to share the "Utility APIs" page; for the return-value and error-code conventions they follow, see Utility APIs.
