5a65ec0aff Add uv_handle_{get,set}_data functions that's absent in pre-1.19 libuv to make code clearer.
This might be removed when we stop supporting older libuv versions.

bc5aae1579 netmgr: make tcp listening multithreaded.
When listening for TCP connections we create a socket, bind it
and then pass it over IPC to all threads - which then listen on
in and accept connections. This sounds broken, but it's the
official way of dealing with multithreaded TCP listeners in libuv,
and works on all platforms supported by libuv.

70397f9d92 netmgr: libuv-based network manager
This is a replacement for the existing isc_socket and isc_socketmgr
implementation. It uses libuv for asynchronous network communication;
"networker" objects will be distributed across worker threads reading
incoming packets and sending them for processing.

UDP listener sockets automatically create an array of "child" sockets
so each worker can listen separately.

TCP sockets are shared amongst worker threads.

A TCPDNS socket is a wrapper around a TCP socket, which handles the
the two-byte length field at the beginning of DNS messages over TCP.

(Other wrapper socket types can be implemented in the future to handle
DNS over TLS, DNS over HTTPS, etc.)
