--
Previously, if a host had both a SRV record for hkp and hkps, the
wrong port was used for the protocol that was used second, because the
hostinfo did not store a port per protocol, and the hosttable does not
discriminate between hosts using the protocol.
Fix this by querying the SRV records on demand, storing a port per
protocol, and returning the right port.

This small patch was submitted along with this comment:
We've been having issues over at Arch Linux with the new libdns
code. Our /etc/nsswitch.conf contains the following line:
hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname
And it turns out dirmngr fails to parse the negation statement (the
bang in !UNAVAIL). This results in gnupg not being able to resolve
any name.
Looking at dirmngr/dns.c it was unclear to me how to properly handle
such negations. The dns_anyconf_scan calls used in
dns_nssconf_loadfile do not allow to store a negation bit easily...
In the meantime, I wrote the attached patch which ignores those
statements altogether. It makes libdns work as expected for us.

Short version: macOS doesn't include /etc/nsswitch.conf and GnuPG's
dirmngr is hard-erroring when that file is missing, such that no DNS
operations succeed and --recv-key returns ENOENT type errors to the
caller.
