2f777ce881 Several core changes to status, soft switches
Regarding soft switches, we had several we should have been listening
for on both reads and writes, but were only doing so on writes; this is
now fixed.

Regarding statuses, we were incorrectly calculating both carry and
overflow. This should now be fixed, although some quick examinations of
disassembly output suggest there is something else amiss. Debugging will
continue shortly.

Mostly for vim to make it easier to skip over blocks with '}'.

bf529d6c9b Finish map, mapper handling for keyboard events
We still need to revise the test code we currently have for handling
keyboard functions; I imagine some code will need to be removed.

05e95d7798 Use bitwise OR, not AND, to add flags.
This was a copy-n-paste oops. I swear I know how bitwise AND and OR
works. Pinky swear!

45eb7b5e58 Add zero page memory mapper functions
This also adds tests for those functions. We have, furthermore, removed
some redundant (and non-externed!) functions from apple2.mem.c which was
the old bank switching code that got moved to apple2.bank.c.

208c909fc2 Memory is determined solely by BANK_ALTZP.
Previously, we just used whatever the segment was that got passed in.
But aside from switching the stack and zero page, ALTZP also changes
where bank-switchable memory is read from and written to; it's either
always aux memory (ALTZP is on) or always main memory (ALTZP is off).

c953616a71 Finish refactor to separate bank_switch and memory_mode
There is one failing test, which I expect to fail at this point; that's
because we need to write a read/write map function for the stack and
zero page so that they use aux memory when BANK_ALTZP is on, and main
memory when not.

ceccacfbc8 Rework bank switch and memory mode into their own fields.
This is to better define and respect the various modes that you can have
in Apple II memory access. This is a work in progress at the moment.

f69454c965 Some soft switches now require consecutive reads
To allow this to work, we had to allow the CPU struct to record what the
last opcode/operand/address were, although in truth we only needed the
last address.
