Dr. David Alan Gilbert 7e555c6c58 migration/postcopy: Add max-postcopy-bandwidth parameter 
Limit the background transfer bandwidth during the postcopy
phase to the value set on this new parameter.  The default, 0,
corresponds to the existing behaviour which is unlimited bandwidth.

/*
* Notably absent: Proper permission management. This is sad, but it seems
* almost impossible to achieve without changing the semantics and thereby
* limiting the use cases of the qemu-io HMP command.
*
* In an ideal world we would unconditionally create a new BlockBackend for
* qemuio_command(), but we have commands like 'reopen' and want them to
* take effect on the exact BlockBackend whose name the user passed instead
* of just on a temporary copy of it.
*
* Another problem is that deleting the temporary BlockBackend involves
* draining all requests on it first, but some qemu-iotests cases want to
* issue multiple aio_read/write requests and expect them to complete in
* the background while the monitor has already returned.
*
* This is also what prevents us from saving the original permissions and
* restoring them later: We can't revoke permissions until all requests
* have completed, and we don't know when that is nor can we really let
* anything else run before we have revoken them to avoid race conditions.
*
* What happens now is that command() in qemu-io-cmds.c can extend the
* permissions if necessary for the qemu-io command. And they simply stay
* extended, possibly resulting in a read-only guest device keeping write
* permissions. Ugly, but it appears to be the lesser evil.
