In this file I introduce the pattern of documenting <dataset>ent
functions that hold internal iteration state with @mtasurace{:<dataset>}
and, in addition to it, for those that use a static buffer to hold the
return value, @mtasurace{:<dataset>buf}.
for ChangeLog
* manual/socket.texi: Document MTASC-safety properties.
