dirmngr: Add workaround for broken getaddrinfo.
* 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. Signed-off-by: Werner Koch <email@example.com>
