ls-remote: create '--sort' option

Create a '--sort' option for ls-remote, based on the one from for-each-ref. This e.g. allows ref names to be sorted by version semantics, so that v1.2 is sorted before v1.10. Signed-off-by: Harald Nordgren <haraldnordgren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
