The 3 version fields should go into a single version struct. (This
is especially important since, currently, pkg->version can easily
be mistaken for pkg_verson_str_alloc(pkg) although they are very
distinct. This has been the source of multiple bugs.
The 3 state fields could possibly also go into their own struct.
All fields which deal with lists of packages, (Depends,
Pre-Depends, Provides, Suggests, Recommends, Enhances), should each
be handled by a single struct in pkg_t
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,
but probably not since most often we only create new pkg_t structs,
we don't often free them. */
