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.

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).

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.

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.

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.

Both main and auxiliary memory need to keep an extra 4k of memory that

within the main and aux segments.
