[libvirt] [PATCH 0/4] Support for sending signals to guest processes



One of the things people want to be able todo with LXC is to send
arbitrary signals to processes inside the container. This series
introduces a virDomainSendProcessSignal API for that purpose. The
LXC driver impl is limited to sending signals to the "init" pid
(ie pid == 1), but in the future we'll extend this to arbitrary
container PIDs (via /proc/$PID/ns/pid + setns()).

If the QEMU guest agent had a suitable command we could support
this for QEMU too.
