David Haywood 9592cff5b3 resurrect some old MVS multi-slot code
this is mostly functional but about 2 years old now, and badly needs some modernizations.  It's a bit ugly in places because I've had to make sure the legacy methods work too, although in other places simply because it's old code I never quite got around to cleaning up.

basically the inits have been split into ones that need calling once on startup (decryptions etc.) and ones that need calling when a new slot is activated (custom banking / protection handlers)

mame64 neogeo -cart1 kof98 -cart2 kof99 -cart3 kof2000 -cart4 kof2001 -cart5 kof2002 -cart6 kof2003
works, assuming you have the RAM.  certain combinations / orders don't work, maybe the real system is like that, maybe there are flaws in the implementation.

once loaded as multi-game the neogeo will run through the attracts of each game in order, if you insert a coin then you can select next / previous game with the '3' and '4' (which are mapped to those buttons on the system) just like real hardware.

if you're low on memory try
mame64 neogeo -cart1 lbowling -cart2 samsho -cart3 mutnat -cart4 pbobblen -cart5 neomrdo -cart6 turfmast
instead

if you want an example of where it fails right now then put -cart1 roboarmy in slot 1 instead, it hangs after cycling through the games (or moving through them with 3) it's possible something isn't reset properly.  This might become clearer as I clean things up a bit.

I've verified eas and neocdz work as before
