addresses used as part of code execution (ie, from the PC) during emulation.
This gives Distella much more information than can be determined from a
static analysis alone, resulting in an extremely accurate disassembly.
This also allows to generate very accurate debugger .cfg files.
Not all carts have been ported to this new scheme yet, particularly ones
having extended RAM that can be mapped out dynamically.
Note that this new scheme doubles the amount of RAM used for storing ROM
images, so up to 128KB extra will be used. There's also a small runtime
check for each instruction executed. Preliminary testing doesn't show
any slowdowns, but we'll see how it goes.

'Stephen Anthony' (aka, me) in addition to Brad Mott as copyright
holders for Stella. I think I've been with the project long
enough now (almost 10 years) to justify being specifically mentioned
above and beyond 'the Stella Team'.

classes. First off, the distella code has been integrated into a
DiStella class. This code isn't yet tied to the debugger, but it does
at least compile and generate valid output.
The RamDebug class has been replaced by a CartDebug class, which
takes responsibility for the previous RamDebug stuff as well as
things related to Cart address space (read from write ports,
disassembly, etc).
Fixed E7 bankswitching when reading from the write port in the upper
256byte area.
Fixed 'read from write port functionality' in general for all carts
that supported it previously. Basically, if _rwport is enabled, the
address is checked to be an actual read (vs. one that's part of a
normal write cycle), *and* it's actually an illegal access (each
cart/bankswitch type now provides a hint to indicate this condition).
Still TODO is clean up the rework, properly integrate DiStella, and
fix labels and defines (which seem to be completely broken).
