alpm_list : add new alpm_list_diff_sorted function
This is more efficient than alpm_list_diff since it assumes the two lists are sorted. And also we get the two sides of the diff. Even sorting should more efficient than the current list_diff. Sorting the two lists should be O(n*log(n)+m*log(m)) while the current list_diff is O(n*m). So I also reimplemented list_diff using list_diff_sorted.
