Support set the CPU affinity of the live migration thread to improve
the migration performance in specific cases. By default, the migration
thread shares CPU resources with the VM process. With those API, support
pin migration thread to expected CPU list to avoid preempting CPU
resources of VM process.
New API 'pinMigrationThread' and virsh command 'virsh migrationpin'
is used to pin migration thread to expected CPU list before or during
migration.
New migration param 'migration.pin' is used to support migration pin
via interface 'virDomainMigrateToURI3'.
