        Valgrind:

        * binparser.c (bin_parser_free): Add this function

        * elfparser.c (elf_parser_free): Call bin_parser_free()

        * sysprof.c (compute_text_width, add_text): Plug leaks

        * collector.c (add_trace_to_stash): Copy n_addresses to a stack
        variable instead of reading it out of the mmap'ed area all the
        time. (That way if there is an overrun, we won't write too much
        into the address array).
