qcow2: Add bdrv_discard support

This adds a bdrv_discard function to qcow2 that frees the discarded clusters.
It does not yet pass the discard on to the underlying file system driver, but
the space can be reused by future writes to the image.

scsi hotplug: Set DriveInfo member bus correctly

drive_init() picks the first free bus and unit number, unless the user
specifies them.

This isn't a good fit for the drive_add monitor command, because there
we specify the controller by PCI address instead of using bus number...

r3480 added this check to account for the entry vector 0xfff00100 to be

Moreover, BIOS size check is already done previously, so this part can...
