Expose more out/readfuncs support functions.
Previouslybcac23d exposed a subset of support functions, namely theones Kaigai found useful. In20160304193704.elq773pyg5fyl3mi@alap3.anarazel.de I mentioned thatthere's some functions missing to use the facility in an externalproject.To avoid having to add functions piecemeal, add all the functions whichare used to define READ_* and WRITE_* macros; users of the extensiblenode functionality are likely to need these. Additionally exposeoutDatum(), which doesn't have it's own WRITE_ macro, as it needsinformation from the embedding struct.Discussion: 20160304193704.elq773pyg5fyl3mi@alap3.anarazel.de
