commit 0698324cde3e0cef7eeb6cfd1640c5eefdf13698
Author: Werner Koch <wk at gnupg.org>
Date: Thu Aug 11 20:46:51 2016 +0200
common: New function string_to_u64.
* common/stringhelp.c (string_to_u64): New.
* dirmngr/http.c (longcounter_t): Remove.
(struct cookie_s): Change content_length to uint64_t.
(parse_response): Use string_to_u64.

Meanwhile we allow some C99 features including stdint.h. Thus we can
simplify things now.
