Public API for parallel migration

Browse Source 
This patch adds a new VIR_MIGRATE_PARALLEL flag for migration APIs which
will ask the hypervisor to use multiple parallel connections for
migrating a domain. The number of parallel connections can be set using
VIR_MIGRATE_PARAM_PARALLEL_CONNECTIONS typed parameter.
