Refactor the API structure, simplifying lifetimes and generics.
- Stack is now a thin handle that implements Copy+Clone. Instead of passing &Stack around, you can now pass Stack.
- Stack and DnsSocket no longer need a generic parameter for the device driver.
- The run() method has been moved to a new Runner struct.
- Sockets are covariant wrt their lifetime.
- An implication of the refactor is now you need only one StaticCell instead of two if you need to share the network stack between tasks.
Use standard core::net IP types instead of custom ones from smoltcp.
Update to smoltcp v0.12.
Add mdns Cargo feature.
dns: properly handle AddrType::Either in get_host_by_name()
dns: truncate instead of panic if the DHCP server gives us more DNS servers than the configured maximum.
stack: add wait_link_up(), wait_link_down(), wait_config_down().
tcp: Add recv_queue(), send_queue().
tcp: Add wait_read_ready(), wait_write_ready().
tcp: allow setting timeout through embedded-nal client.
tcp: fix flush() hanging forever if socket is closed with pending data.
tcp: fix flush() not waiting for ACK of FIN.
tcp: implement ReadReady, WriteReady traits from embedded-io.
udp, raw: Add wait_send_ready(), wait_recv_ready(), flush().
udp: add recv_from_with(), send_to_with() methods, allowing for IO with one less copy.
udp: send/recv now takes/returns full UdpMetadata instead of just the remote IpEndpoint.
raw: add raw sockets.

Added ReadReady and WriteReady impls on TcpSocket.
Avoid never resolving TcpIo::read when the output buffer is empty.
Update to smoltcp v0.11.
Forward constants from smoltcp in DNS query results so changing DNS result size in smoltcp properly propagates.
Removed the nightly feature.
