Added xbps_get_pkg_plist_dict_from_repo().
This function will fetch a requested plist file in a binary package matching its 'pkgname' object by searching in repository pool. This works in any kind of repository, local and remote. Some code was Taken from NetBSD's pkg_install HEAD. Oh, and it's on-the-fly! doesn't need to download the binpkg first! --HG-- extra : convert_revision : xtraeme%40gmail.com-20091125020936-7uf2ncrf1692c5hz
