atapi: GESN: implement 'media' subcommand
Implement the 'media' sub-command of the GET_EVENT_STATUS_NOTIFICATION
command. This helps us report tray open, tray closed, no media, media
present states to the guest.
Newer Linux kernels (2.6.38+) rely on this command to revalidate discs
after media change.
This patch also sends out tray open/closed status to the guest driver
when requested e.g. via the CDROM_DRIVE_STATUS ioctl (thanks Markus).
Without such notification, the guest and qemu's tray open/close status
was frequently out of sync, causing installers like Anaconda detecting
no disc instead of tray open, confusing them terribly.
