Fix CGB timings

Changing the timings of memory writes so they’re not effectively one T-cycle late. This screws up APU’s cycle accuracy for now.

Rewrote PPU (currently only emulates DMG correctly) to use the new timing mechanism. Removed “future interrupts” (No longer required because SameBoy is now T-cycle based)

Complete rewrite of the APU. Channel 3 is complete and passes all the relevant tests from blargg’s suite, as well as PCM34-based tests. Actual sound output is basic and limited, though.

- Added audio supersampling support to greatly improve audio quality.
...
- Fixed a bug where low sampling rate or disabled sound resulted in wrong APU behavior.
- Added API to get the current number of pending samples.
- This change broke save state compatibility with v0.8 and older
Closes #8 .

More accurate FPS capping that tracks time correctly even when the screen is off. Should also support restarting the LCD during blank to increase FPS to 63.

Stabilizing API: New joypad, debugger and reset APIs; internal APIs and direct struct access are no longer available without defining GB_INTERNAL. The SDL port uses the new “public” APIs, as well as most of the non-debug Cocoa code.
