[PATCH V2 17/20] include: Define constants for parallel save/restore

From: Claudio Fontana <cfontana(a)suse.de&gt; Add a new VIR_DOMAIN_SAVE_PARALLEL flag to the save and restore APIs, which can be used to specify the use of multiple, parallel channels for saving a domain. The number of parallel channels can be set using the VIR_DOMAIN_SAVE_PARAM_PARALLEL_CHANNELS typed parameter.
