include: Define constants for parallel save/restore

Browse Source 
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 and restoring a domain. The number of parallel channels
can be set using the VIR_DOMAIN_SAVE_PARAM_PARALLEL_CHANNELS
typed parameter.
