This adds support for either all udp or all tcp|tls resolvers. At a later stage, we can of course support mixed sets of resolvers (especially with the previous commit paving this path).
…e.connect This avoids the need to unmarshal the arguments for a Dns_stub.t instantiation, and makes the surface more uniform.
similar to qubes-mirage-firewall (thanks @palainp), at initialization time a single udp_port is reserved as last resort. In general, the UDP source port is randomized, and UDP.listen/unlisten are executed on that port (which is as well registered / unregistered). If the port allocation fails, the last_udp_port is used, which is always listened to.

previously, the source port of the remote (usually 53) was checked against our source port (some random ephemeral), leading to no accepted reply. the mirage udp interface does not provide the destination port in the callback (report as mirage/mirage-tcpip#497).
