dirmngr: Implement a getaddrinfo wrapper.
* dirmngr/dns-stuff.h: Include some header files.
(dns_addinfo_t, dns_addrinfo_s): New.
* dirmngr/dns-stuff.c: Always include DNS related headers.
(free_dns_addrinfo): New.
(resolve_name_standard): New.
(resolve_dns_name): New.

* dirmngr/t-dns-stuff.c: Include netdb.h.
(main): Keep old default mode with no args but else print outout of
resolve_dns_name.  Revamp option parser.
--

This wrapper allows us to switch to ADNS and thus Tor for standard
name resultion.

The patch for http.c is a sanity check because tor mode is anyway

Given that libgpg-error is a dependency of all GnuPG related libraries
it is better to define such macros at only one place instead of having
similar macros at a lot of places.  For now we need repalcement
macros, though.

stdout reader after EOF from read_log_data.
* dirmngr/crlcache.c (crl_cache_reload_crl): Close the reader before

--

I assumed that the log_fd also has a reader object but that reader
object is used for stdout and needs to be closed by the consumer.

The real bug with the non-released ldap_wrapper control objects was
that when looping over distribution points we did not closed the used
reader object before the next iteration.  Now, the test case had more
than one DP and thus we lost one reader object.

--

The major bug here was that on an EOF of the log fd the log fd was not
closed and thus the final queue item removal could not work.  Checking
the queue on a timeout is not really necessary but it help in case
there is a race condition lingering.

This is because on 64 bit systems "sizeof aptr > sizeof aint" and thus
Valgrind complains about this.  It is no a real problem because we

sprintf has been replaced by snprintf to avoid warnings on some
platforms.

xfree et al. is required so that replacement functions are
used if defined.  For example the Libgcrypt functions which may not be
fully compatible with standard free.

Impossible conditions should use GPG_ERR_INTERNAL.
