blockdev: read-only-mode for blockdev-change-medium
Add an option to qmp_blockdev_change_medium() which allows changing the
read-only status of the block device whose medium is changed.
Some drives do not have a inherently fixed read-only status; for
instance, floppy disks can be set read-only or writable independently of
the drive. Some users may find it useful to be able to therefore change
the read-only status of a block device when changing the medium.
