Add rom, ram2 bank memory; modify read/write sig
...
The signature for read/write map functions now accepts a void pointer so
that we can pass in the machine that those functions may need to know
about. This is a bit hairy, but allows us to avoid the need for a
yet-uglier global variable.

Small bug in the jump label code for IND
...
This also required a rethink on some core functions which now needed to
know about the memory segment; and further changes in the unit-testing
code on the disassembly suite was also necessary.

Switch references from SDL_Rect to vm_area
...
We still use SDL_Rect internally, but we want to abstract the use of it
in our API. The only thing the rest of the app should care about is the
vm_area struct.

Add ability to set logical size of window at any time
...
We also removed the scale field, as the screen does not expect to manage
its own logical coordinates in SDL.
Additionally, we added an xcoords and ycoords function to the screen
externs so that you don't have to "know" that screen has those as
fields.
