ORG rework, part 2

Browse Source 
AddressMap API reshuffle.  Added "pre-label" to class and API.  Split
AddressMapEntry into two parts to make it clear when FLOATING_LEN
has been resolved.

Updated display line list generator to use in-line linear map
traversal.  Previous approach was to walk through the list of regions
in a second pass, inserting .ORG directives, but that was awkward
and is no longer needed.
