dirmngr: Use the new DNS wrapper for the HKP engine.
* dirmngr/ks-engine-hkp.c (my_getnameinfo): Change arg type to
dns_addrinfo_t.
(map_host): Replace getaddrinfo by resolve_dns_name.
--

Note that we still need to replace getnameinfo so that the PTR lookup
is either suppressed or also done via ADNS.

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

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

Using the homedir for extra-certs and trusted-certs makes

provide those through the SENDCERT command.
You can use trusted-certs and extra-certs to provide
users with a base of locally available certificates that are
not already in store of the applications.

Only report support for the hkps scheme when GnuPG / dirmngr

This helps debuging and enable the user to detect whether support
for hkps is included by doing a
`gpg-connect-agent --dirmngr 'keyserver --help' /bye`.
Currently hkps will be listed as a supported scheme but trying to
add a keyserver using it will silently fail.

As a digression, https is never listed as a valid scheme.

gnulib has always been a cause of trouble in GnuPG because we used
only a very few functions and the complex include machinery of gnulib
is quite complex and the cause for many build problems for example on
OS X.  This is not gnulib's fault but due to our limited use of gnulib
and that we only rarely update the gnulib code to avoid regressions.

In part two we will address the functions

 mkdtemp
 setenv
 unsetenv
 strpbrk

which may bot be implemented on all platforms.  They are not required
on a libc based system.

--

In the course of building GnuPG 2.1.0 beta864 on debian, i found that
several of the installed executables were linked to libraries that
they did not need to be linked to, which would cause unnecessary
package dependencies at runtime.

The changeset here removes these unnecessary libraries from linking.

Something similar could possibly also be done by passing --as-needed
to the linker, but trimming the depenencies seems more parsimonious.
