* imagedev/cassette: add bitwise operators for cassette_state so a lot of ugly casts can go away
* audio/leland.cpp, cubeqst.cpp: make better use of loops in machine configuration
* screen: validate crystal values used for set_raw
* driver: get rid of sound start/reset overrides in machine configuration
* vrender0.cpp, nexus3d.cpp: corrected pixel clock crystal value
* mw8080bw.cpp: turned several audio subsystems into devices
* bus/sat_ctrl: don't start subdevices in device_start - the machine does it for you
* mb14241.cpp: simplify handlers
* fgoal.cpp: updated for simplified handlers
* devfind, screen: repair some doxy comments that had rotted with refactoring
* doxygen: disable warnings for undocumented things - it's most of our codebase
* snowbros.cpp: restore an output level setting lost in MCFG removal
There's an outstanding validation error from the HP98543 DIO video card
not using a valid crystal value. Someone needs to find a picture of the
card and confirm or deny the existence of the 39.504MHz crystal.
The various start/reset overrides are bugs waiting to happen. It's not
immediately obvious that the ones run earlier can end up being called
multiple times if subsequent ones throw missing dependencies exceptions.
They're a relic of when everything from the old C-style drivers was
thrown into classes all jumbled together.
I haven't tested the hh_sm510.cpp changes very well yet - I'll give it
another review soon, and test it some more before the end of the month.
I'm not sure about whether any of the B or BA handlers should be in the
base config methods for G&W. I've left them there for some
configurations that always have them, but I might rip them out of the
common methods altogether. It's not like Tiger where all the games use
them.
