[libvirt] [PATCH 4/4] lxc: store tty pid

[Dave Leskovec <dlesko linux vnet ibm com>]

This patch will use a file in the lxc configuration directory to store the tty
forwarding process pid.  The pid is stored after the process is fork()'d.  It's
loaded during startup when the config for a running container is loaded.  The
file is deleted when the domain is undefined.  This should avoid "losing" the
tty pid over a libvirtd restart.
