Implement migration via unix sockets.  While you can fake this using
exec and netcat, this involves forking another process and is
generally not very nice.  By doing this directly in qemu, we can avoid
the copy through the external nc command.  This is useful for
implementations (such as libvirt) that want to do "secure" migration;
we pipe the data on the sending side into the unix socket, libvirt
picks it up, encrypts it, and transports it, and then on the remote
side libvirt decrypts it, dumps it to another unix socket, and
feeds it into qemu.

The implementation is straightforward and looks very similar to
migration-exec.c and migration-tcp.c


It would be nice to support migration via arbitrary fd using the recent SCM_RIGHTS support.
