We were using a void *data element in pmpkg_t before, which is unsafe by its nature of being untyped. Reimplement data as origin_data being a union that can hold either a path to a package file or a pointer to a cache database, and make the other necesary updates in the code to reflect this. See package.h for details. Signed-off-by: Dan McGee <dan@archlinux.org>
