The initialization of drivers happens in a separate thread.
However, the main thread continues initialization and sets
shutdown callbacks (virStateShutdownPrepare() and
virStateShutdownWait()) even though the driver init thread is
still running. This is dangerous because if the daemon decides to
quit early (e.g. because SIGINT was delivered) the
shutdownPrepare and shutdownWait callback are called over
partially init drivers.
Set callbacks only after all drivers were initialized.

However other cpu drivers do not have the 'getHostData' function
implemented.
Skip the comparison if we do not have host CPUData available,
since virCPUDataIsIdentical always returns an error in that case.

Non-shared storage migration of guests which are disk I/O intensive and
have fast local storage may actually never converge if the guest happens
to dirty the disk faster than it can be copied.
This patch introduces a new flag
'VIR_MIGRATE_NON_SHARED_SYNCHRONOUS_WRITES' which will instruct
hypervisors to synchronize local I/O writes with the writes to remote
storage used for migration so that the guest can't overwhelm the
migration. This comes at a cost of decreased local I/O performance for
guests which behave well on average.
