libxbps: * Added xbps_set_cachedir() and xbps_get_cachedir(). By default it's set to /var/cache/xbps if not specified and it's always relative to the root directory. * Move mkpath() code from sync_remote_pkgidc.c into its own file mkpath.c to use it in another parts of the code. * Added xbps_get_binpkg_local_path(), that returns the local path to a binary package file, stored in cachedir or local repo. * Remote pkg index files are now stored directly in metadir/repodir, skipping the arch directory because binpkgs are now in cachedir. xbps-bin: * Added -c flag to set the cachedir. * Check sha256 hashes in the download stage so that it can check a downloaded binpkg immediately once is stored. * If a binpkg doesn't match the hash it will be refetched. Bump XBPS_RELVER to 20091128. --HG-- extra : convert_revision : xtraeme%40gmail.com-20091128013841-kkcvk07lsqdr26w8
