++ The 3 state fields could possibly also go into their own struct.

++
++ All string fields for which there is a small set of possible
++ values, (section, maintainer, architecture, maybe version?), that
++ are reused among different packages -- for all such packages we
++ should move from "char *"s to some atom datatype to share data
++ storage and use less memory. We might even do reference counting,
