In get_mem_values we open the process without PROCESS_VM_READ access
and are *still* able to request working set information, despite
MSDN claiming we need it for this purpose. Instead of adding this
access right, just add an comment to point this out for now.

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.

to get information of heap virtual memory blocks. Store heap id and
flags, as well as end address of each block.
(heap_info::fill_if_match): Check incoming base address against full
address range of heap chunks. Convert flag values in extra heap
information.
(format_process_maps): Change order so that heap check is done before
MEM_MAPPED check since there are shareable heaps.
