* dirmngr/dns-stuff.c: Include npth.h
(my_unprotect, my_protect): New wrapper.
(resolve_name_adns): Put unprotect/protect around adns calls.
(get_dns_cert): Ditto.
(getsrv): Ditto.
(get_dns_cname): Ditto.

* dirmngr/dns-stuff.c (tor_credentials): New.
(enable_dns_tormode): Add arg new_circuit and update tor_credentials.
(my_adns_init): Rework to set Tor mode using a config file options and
always use credentials.
* dirmngr/server.c (cmd_dns_cert): Improve error message.
* dirmngr/t-dns-stuff.c (main): Add option --new-circuit.
--
Note that the option --new-circuit in t-dns-stuff is not really useful
because a new circuit is also used for the first call to the function.
Todo: We need to find a policy when to requrest a new curcuit and we
also need to add credentials to the assuan_sock_connect calls.

(getsrv): Run srand only once.
* dirmngr/t-dns-stuff.c (main): Allow passing another name for --srv
and change output format.
* dirmngr/dns-stuff.c: Replace all use of default_errsource.
(my_adns_init): Move to top.
(resolve_name_adns): New.
(resolve_dns_name) [USE_ADNS]: Divert to new func.

* dirmngr/dns-stuff.c (is_onion_address): New.
* dirmngr/ks-engine-hkp.c (hostinfo_s): Add field "onion".
(map_host): Special case onion addresses.
(ks_hkp_print_hosttable): Print an 'O' for an onion address.
* dirmngr/http.c (connect_server): Special case onion addresses.
--
Note that this requires the latest libassuan from git. Onion addresses
are always support regardless of the --use-tor flag.

* dirmngr/http.c (connect_server) [W32]: Remove gethostbyname hack;
we require getaddrinfo anyway.
* dirmngr/dns-stuff.c (AI_ADDRCONFIG): Add replacement if not defined.
(map_eai_to_gpg_error) [W32]: Take care of unsupported codes.

* dirmngr/dns-stuff.c (resolve_name_standard): On failure retry by
first resolving the CNAME.
(get_dns_cname): New.
* dirmngr/t-dns-stuff.c (main): Add option --cname.
--
At least the getaddrinfo implementation in glibc 2.19-13 from Debian
returns EAI_NONAME if the CNAME points to a too long list of A/AAAA
addresses. Looking at the wire the data is correctly returned from
the server but getaddrinfo seems to get confused by truncation and
retry. To fix this we resolve the CNAME again and call getaddrinfo
again with the canonical name.

(my_adns_init): new.
(getsrv)[USE_ADNS]: Use my_adns_init.
(getsrv)[!USE_ADNS]: Return an error if Tor mode is active.
* dirmngr/t-dns-stuff.c: Add option --use-tor.

* dirmngr/dns-stuff.c (getsrv): Replace MAXDNAME.

(struct srventry): Use a fixed value instead of MAXDNAME.
* dirmngr/http.c (connect_server): Use DIMof instead of MAXDNAME.
Malloc a helper array.
--
Depending on the order of included headers it might be that we allocate
the array with a different size than what we test against in another
module. To make it more robust we use the actual known size of
checking.
A better would be to use a linked list and avoid these large arrays.

* dirmngr/dns-stuff.c: Bail out if neither ADNS nor getaddrinfo is
available.
--
We used to have replacement code for getaddrinfo and thus check for it
in configure. However, this was for the old http and dns-cert code
from common/. For dirmngr I made liberal use of getaddrinfo w/o
without checking. Just in case someone tries to build on an old
platform we now error our with a suitable #error.

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