Adding multiple questions on a single DNS query is not supportted by
most DNS servers. This patch issues two separate DNS queries
sequentially for ipv4 and then for ipv6.
Fixes: https://savannah.gnu.org/bugs/?39710
* grub-core/net/bootp.c (parse_dhcp_vendor): Add DNS option.
* grub-core/net/dns.c (grub_dns_qtype_id): New enum.
* (grub_net_dns_lookup): Now using separated dns packages.
* (grub_cmd_nslookup): Add error condition.
* (grub_cmd_list_dns): Print DNS option.
* (grub_cmd_add_dns): Add four parameters: --only-ipv4,
* --only-ipv6, --prefer-ipv4, and --prefer-ipv6.
* include/grub/net.h (grub_dns_option_t): New enum.
* (grub_net_network_level_address): option added.
