APU glitch: When turning the APU on while DIV's bit 4 (or 5 in double speed mode), the first DIV/APU event is skipped.

Components not affected by CGB’s double speed mode now operate in 8MHz mode to theoretically make advance_cycles(gb, 1) safe.

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 .

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.
