New _alpm_find_dep_satisfier function
This function finds the first satisfier package in a pkglist. Using it instead of _alpm_find_dep_satisfiers eliminates some memleaks and it is faster. (_alpm_find_dep_satisfiers and _alpm_find_pkg_satisfiers will be removed soon.) Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>
