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.
