r->buf is hardcoded to 2056 which is (256 + 1) * 8, allowing 256 luns at
most. If more than 256 luns are specified by user, we have buffer
overflow in scsi_target_emulate_report_luns.
To fix, we allocate the buffer dynamically.

If user does not specify a serial id, e.g.
-device virtio-blk-pci,serial="serial_id"
or
-drive serial="serial_id"
no serial id will be assigned.
Add a default serial id in this case to help identifying
the disk in guest.

This is on top of Paolo and Nick's work.
Current status:
Basically, tcm_vhost + seabios works now. We still have one more issue,
vhost_verify_ring_mappings fails. The hotplug also works with the latest
tcm_vhost.ko hotplug patch.
Asias He (1):
disable vhost_verify_ring_mappings check
Device needs the exact size of these data structure. Prevent padding.
This fixes guest hang when booting seabios + tcm_vhost.

Before we start scsi target scanning, we need to set the
VIRTIO_CONFIG_S_DRIVER_OK flag so the device can do setup properly.
This fix a bug when booting tcm_vhost with seabios.
