ATAPI optical drive support

Add support for ATAPI optical drives (CD/DVD/BD-ROM).

Although these devices use SCSI commands transported over ATA/PI, for the initial implementation it would be smarter to extend the ATA driver with simple specialized support for ATAPI drives rather than attempting to convert it to a generic SCSI HBA driver.

See also ticket #140 (ISO 9660).

Minimalistic ATAPI CD-ROM support is available as of changeset:mainline,847. It is only tested with Qemu and seems to read the HelenOS CD image through Qemu's ATAPI without problems. I've only looked at the data using bdd, so it would be nice to try this with the cdfs driver. I will test this with a real optical drive (my LG BD reader/writer) when I get home.

Note that the driver currently does not report media capacity for CD-ROM.
