DDC_DEVICEs are control points for high-end monitors such as the
HP DreamColor. The DDC/CI interface allows userspace applications
to upload custom colorspaces and interact with the display without
using the monitor hardware controls.
Previously we checked the SysV priority value to figure out if a SysV
unit was enabled or not, since th value was mostly read from the S
startup links. Since we read this value from the LSB headers as a
fallback we hence ended up considering a lot more services enabled than
were actually enabled.
This patch adds an explicit boolean which encodes whether a sysv service
is enabled or not via S links.

For example, not all systems have PROC_KCORE enabled. Avoid a broken symbolic
link in those cases.

Extend the DVD+RW/DVD-RAM check in commit 1ef6c9e to also cover DVD-RW, since
in "restricted overwrite" mode they behave similar to DVD+RW.

Those do not yet support the 0x46 "GET CONFIGURATION" support. If we have
those, fall back to the 0x51 "READ DISC INFORMATION" call. This can only
differentiate between CD-RW and CD-R, but first that's better than a complete
detection failure, and second, those old drives likely don't support more
modern media in the first place.

Once formatted, DVD+RW and DVD-RAM discs are always reported "complete" by the
drive. Check the if the Volume Descriptor or Volume Descriptor Anchor sectors
are empty, and if so, set the status to blank. If the disc is unformatted the
blank status is maintained and no reads are issued. If the disc is formatted and
read command fails, the status remains set to complete to avoid accidental
blanking.

We should do only do classes of devices, not individual pieces
of hardware.
There is no way for us to manage this in the long term, and it needs
to be thought through what we want here, but it surely isn't a list of
smartphones in the udev source tarball installed on all systems.
