This is different problem (and different code) than user IDs. I do
think the keyserver helpers should handle IDNA for keyserver
hostnames. This should not be part of gpg, though. Let gpg pass the
utf8 keyserver name to the gpgkeys_foo program and if gpgkeys_foo
needs to do IDNA-to-ascii that should be done there.
I hear the curl people are planning on IDNA support, so if we do end
up using curl for the HTTP-ish keyservers, this may happen
