Looks like Amos went offline: but yes, in a nutshell.
addr parsing now relies on qemu-sockets.c:inet_parse(), which has supported
[ip6addr]:port for a while, as opposed to net.c:parse_host_port(), which
didn't.
Additional Error-handling was added to
qemu-sockets.c:inet_connect()/inet_listen(), along with non-blocking support
for inet_connect(), to subsume the ad-hoc client/server setup in
migration-tcp.c
