Allow the port 'id's to be set by a user on the command line. This is
needed by management apps that will want a stable port numbering scheme
for hot-plug/unplug and migration.
Since the port numbers are shared with the guest (to identify ports in
control messages), we just send a control message to the guest
indicating addition of new ports (hot-plug) or notifying the guest of
the available ports when the guest sends us a DEVICE_READY control
message.

If the host connection to a port is closed on the destination machine
after migration, whereas the connection was open on the source, the
guest has to be informed of that.
Similar for a host connection open on the destination.

If some ports that were hot-plugged on the source are not available on
the destination, fail migration instead of trying to deref a NULL
pointer.

The number of ports on the source as well as the destination machines
should match. If they don't, it means some ports that got hotplugged on
the source aren't instantiated on the destination. Or that ports that
were hot-unplugged on the source are created on the destination.

The target could be started with max_nr_ports for a virtio-serial device
lesser than what was available on the source machine. Fail the migration
in such a case.

What is known today as bdrv_open2 becomes the new bdrv_open. All remaining
callers of the old function are converted to the new one. In some places they
even know the right format, so they should have used bdrv_open2 from the

Since commit 8da3ff180974732fc4272cb4433fef85c1822961 ("MMIO callback
interface changes"), the addresses passed to the I/O functions are an
offset to the start of the area. As a consequence, there is no need to
correct the address using the value of IOBR. This make possible the use
of the default MMIO functions. Moreover the addresses are now remaped
when the value if IOBR change.
The memory area corresponds to the devices behing the PCI bus, it should
not be mapped by the PCI controller. Remove the corresponding code.
