blockdev: Store -drive option media in DriveInfo

DriveInfo is closely tied to -drive, and like -drive, it mixes
information about host and guest part of the block device.  Unlike
DriveInfo, BlockDriverState should be about the host part only.

One of the remaining guest bits there is the "type hint".  -drive
option media sets it, and qdevs "ide-drive", "scsi-disk" and non-qdev
IF_XEN devices check it to pick HD vs. CD.

Communicate -drive option media via new DriveInfo member media_cd
instead.
