Get rid of a couple of copies of the CC0 text. Add header comment to
CC0 files to remind people editing them what the terms are. Also add
some missing XML headers. The header comments in layouts won't bloat
the binary - they get stripped out before compressing, same as any other
comments.
- Set width and endianness for regions, including cartridges
- Make init code safer and more efficient
- De-duplicate some memory maps
- Separate state class for jaguarcd
I've tried to keep this driver from regressing any further than it already has while cleaning up the code and adjusting region usage to comply with the soon-to-be-committed "truth in endianness" requirement. It's possible that some regions should really be 16 bits instead of 32 or vice versa, and/or that DSP endianness may be incorrect.
