dirmngr: Change to new ADNS Tor mode init scheme.
* 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.
