Corinna Vinschen 166d3ddf5a Fix major device check when locking partitions
The change introduced in commit b2867a6 contains a faulty check for
the major device number in fhandler_dev_floppy::lock_partition.
Fix this.  Also fix comments.

Corinna Vinschen b2867a68b9 Handle up to 63 partitions per drive
Revamp device parsing code.  Introducing support for more partitions
into the shilka-generated parser has the unfortunate side-effect of
raising the size of the DLL by almost 2 Megs.  Therefore we split out
the handling for /dev/sdXY devices into a tiny bit of hand-written
code.

While at it, remove some unused cruft from devices.* and generally
clean up the device class to provide access methods instead of direct
access to members.
