[Libvir] [PATCH] virDomainMigrate (version 5) (for discussion only, but getting there)

This is a rolled up patch for virDomainMigrate, including virsh and Python fixes. Changes since last time: - VIR_MIGRATE_LIVE is exported to Python - 'resource' parameter is now named 'bandwidth' - there is now an extra domainMigrateFinish step It needs a bit more testing which I can't do today while I'm at the office. Rich.
