Daniel P. Berrange b8a68728b6 io: fix FD socket handling in DNS lookup
The qio_dns_resolver_lookup_sync() method is required to be a no-op
for socket kinds that don't require name resolution. Thus the KIND_FD
handling should not return an error.

Markus Armbruster a6c76285f2 io vnc sockets: Clean up SocketAddressKind switches
We have quite a few switches over SocketAddressKind.  Some have case
labels for all enumeration values, others rely on a default label.
Some abort when the value isn't a valid SocketAddressKind, others
report an error then.

Unify as follows.  Always provide case labels for all enumeration
values, to clarify intent.  Abort when the value isn't a valid
SocketAddressKind, because the program state is messed up then.

Improve a few error messages while there.

Daniel P. Berrange c1b412f1d9 io: introduce a DNS resolver API
Currently DNS resolution is done automatically as part
of the creation of a QIOChannelSocket object instance.
This works ok for network clients where you just end
up a single network socket, but for servers, the results
of DNS resolution may require creation of multiple
sockets.

Introducing a DNS resolver API allows DNS resolution
to be separated from the socket object creation. This
will make it practical to create multiple QIOChannelSocket
instances for servers.
