API and mechanism to allow generic messages to be inserted into WAL that are intended to be read by logical decoding plugins. This commit adds an optional new callback to the logical decoding API. Messages are either text or bytea. Messages can be transactional, or not, and are identified by a prefix to allow multiple concurrent decoding plugins. (Not to be confused with Generic WAL records, which are intended to allow crash recovery of extensible objects.)
