A hover service to show tool tip text for hovering over a program address in the listing.
The tool tip text shows relationships to key topological elements of the program relative to
the address -- offset from image base, offset from current memory block; if the address is
within the bounds of a function, the offset from function entry point; if the address is within
the bounds of defined data, the offset from the start of the data.
