Added netlist-based audio to early Cinematronics vector games

[aaronsgiles]

• Added netlist simulations for the following games: Space War, Barrier, Star Hawk, Speed Freak, Star Castle, War of the Worlds, Sundance, Tail Gunner, Rip Off, Armor Attack, Warrior, Solar Quest, Boxing Bugs. Removed previous samples-based sound. [Aaron Giles, Couriersud]

• Added built-in minimal artwork for Warrior. [Aaron Giles]

• Changed speaker maximum sample tracking to be based on new compile-time define SPEAKER_TRACK_MAX_SAMPLE instead of MAME_DEBUG. [Aaron Giles]

• Modernized 74164 and 74393 netlist TTL devices. [Aaron Giles]

@aaronsgiles There are only three minor bits of feedback I have, none of which should be blockers for merging, but it would be nice to have them addressed before the Saturday code freeze.

1. In some of the source files (namely the Cinematronics audio device, it looks like), you're using u8 in various places, but I've also seen some spots that use uint32_t. For consistency, it's preferred to have all one style or all the other. Since you've rewritten the majority of the file, it's up to you which one.

2. I'm a little leery of compile-time defines, since it can and does lead to dead, unmaintained code. Being able to track clipping seems like a useful development feature. I would consider having a command-line enable flag.

3. Having a hard-coded magic number of 100000 for the number of samples to reject is a bit eyebrow-raising. If possible, consider allowing the user to supply the number via the command line if the flag outlined in point 2 is supplied.
