Reimplement the send/recv code as migrate

I believe some people did use this, but I had intermittent problems getting it to work reliably.
It has now been re-implemented as a single "migrate" command using ssh.

A guest can now be transferred completely from the source host using a single command.
See the man page for more details

vm migrate -s guest-name new-host

Ideally passwordless key-auth should be used, although not strictly necessary.
