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.

Make vm_area_set be an inline function.
...
Gets most of the benefits of being a macro, but also gains type safety
(which macros do not have).

Use vm_area for draw_rect.
...
This simplifies and to some degree normalizes the way we reference areas
in the vm subsystem.

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.

This involves using glfw. This first commit creates a window but doesn't
do anything with it; it also just hangs until you can escape out
somehow.
