NeoGeo slot work [S. Smith]

Message that was posted to me

"Hi David

It was to my great disappointment that your work on the NeoGeo Multislot (Dec 2013) was not included in MAME.  To aid the process I've taken your work and spent some hours addressing the concerns put forward by the developers.  The code I'm sending to you converts Neo Geo to fully use slot devices for the cartridges and implements the multi-slot using techniques that have greater likelihood of being met with approval.

In some places the slot trampolines caused performance to drop below 100% so I've used methods to avoid them gathered by the study of other slot devices in MESS.  Performance is the same as it was prior to this update.

I first sent this with the forms on the official site but received no reply so I'm turning to you directly.
