Sound and other improvements to Sega G-80 games. (#7103)
Sound and other improvements to Sega G-80 games: [Aaron Giles, couriersud]
* Added netlist-based sound to Eliminator, Zektor, Space Fury, and Astro Blaster.
* Split the Sega Universal Sound Board and Speech Boards into their own separate files.
* Improved Universal Sound Board implementation for better accuracy in Star Trek and Tac/Scan.
* Wrote netlist-based backend for Universal Sound Board; currently disabled due to limitations in the system.
* Wrote netlist-based backend for Speech Board; currently disabled pending future sound system changes.
* Implemented wait states and the vector DRAW flag to help improve timing.
SP0250 Improvements: [Aaron Giles]
* Matched clock divider to real chip measurements.
* Fixed behavior when not fed enough data; addresses "gapping" in speech in Sega games.
* Implemented accurate LFR noise generator according to real chip measurements.
* Added pulse-width modulation DAC output mode for future consumption by netlist.
Netlist additions: [Aaron Giles]
* Added compile-time option to record nltool-compatible CSV files.
* Improved CD4020 implementation.
* Fixed CD4053 behavior.
* Added 74139 device.
* Added TL082 device.
8253 PIT changes: [Aaron Giles]
* Added explicit synchronization to all writes.
* Cleaned up some timing calculations to avoid double<->attotime conversions.
