scan_urlencoded2 - decode urlencoded data

       scan_urlencoded2 behaves like scan_urlencoded, but decodes '+' to ' '.

       See scan_urlencoded(3) for details.

       dest can be NULL. destlen can be NULL. dest can be src.

       scan_urlencoded2("foo%20bar",buf,&i) -> return 9, i=7, buf="foo bar"

       scan_urlencoded2("foo+bar",buf,&i) -> return 7, i=7, buf="foo bar"

       scan_urlencoded("foo+bar",buf,&i) -> return 7, i=7, buf="foo+bar"
