Display @ symbols on startup
...
There's actually a lot going on here to make the @ symbol display
happen.
The @ symbols are the visual representation of NUL-character bytes. They
are inverse video, as dictated by the Apple //e technical reference. As
part of the bootup sequence, those bytes are overwritten with space
characters.
As part of the work, we now have a table of rows and columns that map to
display buffer addresses.

Rewrite status checks with macros
...
This also forces the result of operations to be considered purely as
8-bit results in _some_ cases, but not in others. We were missing some
times when an overflow is the expected behavior; because SET_RESULT()
and mos6502_modify_status() use ints, this overflow was not properly
observed.
