Basic dependency support for pkgfs.
The code looks at db(1) btree files stored in PKGFS_DEPSDIR to know what dependencies are required for X package, and walks the dependency chain every time that X package contains a deps .db file. Every time a package is stowned, the pkg is registered into PKGFS_DESTDIR/.pkgfs-registered-pkgs.db, and removed when it's unstowned. --HG-- extra : convert_revision : b5222a890dd41b96dc72ee3e90bb72a282fe0841
