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.

Add memory injection to 6502; main memory in apple2
...
Note that memory _is_ now managed in apple2, and _not_ in mos6502.

We can no longer assume PC increments during address handling
...
This change required a number of consequent changes to assumptions we'd
made, and I'm not 100% confident we have things right at this point in
time.

Vastly simplify unit tests for mos6502
...
Criterion's init and fini config options allow us to register setup and
teardown functions. We now use this to register the common cpu variable
for the mos6502 tests, albeit through the use of a global variable.
Doing so necessitated that each of the different test files have their
own suites, due to some implementation details in Criterion, but this is
No Big Deal.

Add functions for instructions, cycles, and address modes.
...
This also adds a new table for cycles, and adds unit test functions for
the work as well.
