DHCP is enabled by setting the `ip` config entry to "use_dhcp". Reusing this
config field rather than creating a new one means that there is no ambiguity
over which config field takes precedence.
Adds a thread to configure the interface based on DHCP events
Adds a `Dhcpv4Socket` as a wrapper around smoltcp's version
Formalises the storage of the IP addresses so that we can update one in
another module.
There's also a workaround for the first DHCP discover packet frequently
going missing.

Main changes:
Deal with interfaces now being generic over mediums, update interface name
and initialisation.
Interfaces now own their sockets. So we store a reference to the Interface
instead of the SocketSet in Scheduler and IO.
Sockets are no longer reference counted. We never called the function to
increase the socket's reference count, so now we just remove it where it
was previously released. This will result in the socket being dropped at
a different time, but I think that should be fine.
Tested firmware upload to the bootloader and spamming artiq_coremgmt log
calls to download the log from the firmware.

Remove the implementation of setting keepalive settings on sockets and use
the implementation from sipyco instead.
