- pkg.h, pkg.c (new_pkg, free_pkg): provide package structure definition,
allocation, and deallocation
- fixup.c, gobble.c, prereq.c, qpkg.c: include "pkg.h"
- gobble.c (finish_pkg): use free_pkg instead of just "free" to avoid
leaking memory

- fixup.h, fixup.c (sort_versions): sort package versions
- qpkg.c (do_fixups, main): do fixups when done gobbling
