700bc31465 Copy system rom into $C800..$CFFF; document. 
Things are getting a little hairy...at least, as to my own
comprehension. Documentation is a must.

06d37d24d7 Allow us to call objstore_init more than once. 
This also separates some code into objstore_ready().

Peter Evans
e7a404508e Add init functions for disk2, sys rom 
Also move the defines for bank offset, rom size, etc. into apple2.mem.h
which makes a little more sense.

ee7b5f66b0 Add support for a map machine pointer 
To be sent to the read/write functions that are implemented by said
machine.

834959c10a Add rom, ram2 bank memory; modify read/write sig 
The signature for read/write map functions now accepts a void pointer so
that we can pass in the machine that those functions may need to know
about. This is a bit hairy, but allows us to avoid the need for a
yet-uglier global variable.

b42d5370aa Small bug in the jump label code for IND 
This also required a rethink on some core functions which now needed to
know about the memory segment; and further changes in the unit-testing
code on the disassembly suite was also necessary.
