If more than one instance of xenconsole is run against the same DOMID then each instance will only get some data. This change ensures exclusive access to the console by obtaining an exclusive lock on <XEN_LOCK_DIR>/xenconsole.<DOMID>. The locking strategy used is based on tools/libxl/libxl_internal.c:libxl__lock_domain_userdata().
