Add virDomainSendProcessSignal API
Add an API for sending signals to arbitrary processes in the guest OS. This is primarily useful for container based virt, but can be used for machine virt too, if there is a suitable guest agent, * include/libvirt/libvirt.h.in: Add virDomainSendProcessSignal and virDomainProcessSignal enum * src/driver.h: Driver entry point * src/libvirt.c, src/libvirt_public.syms: Impl for new API Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
