do not infloop on a query ending in %XY, for invalid hex X or Y
When a query ends in say %gg, (or any invalid hex) e.g.,
http://git.gnome.org/browse/gdlmm/commit/?id=%gg
convert_query_hexchar calls memmove(txt, txt+3, 0), and then returns
txt-1, so the loop in http_parse_querystring never terminates. The
solution is to make the memmove also copy the trailing NUL.
