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.
