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.

We still use SDL_Rect internally, but we want to abstract the use of it
