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.

Throughout mmap, size-related variables and parameters are still using
DWORD as type, which disallows mapping ranges > 4Gigs. Fix this by
using SIZE_T throughout for those vars and parameters.
Also, drop unused off parameter from 1st variant of mmap_record::map_pages.
