The DownloadUser option will be used to drop privledges to the specified user when downloading files. The intention is for this to be extended in the future to a more general sandbox configuration to cover operating on package and database files prior to verification. Add this option to pacman configuration and the various accessors into the libalpm backend. Signed-off-by: Allan McRae <allan@archlinux.org>
