- Futher disentangle display, interface, and video backends
- Backend video owns the staging/intermediate framebuffer for now
- Add the beginnings of display update callbacks
- Correctly calculate 7 cycles for handling IRQs
- More frequent calls to MB_UpdateCycles()
- Correctly calculate timing for MB_EndOfVideoFrame() when testing/tracing/debugging
- Supported platforms:
- Mac/iOS (OpenAL)
- Desktop Linux/POSIX (OpenAL)
- Android (OpenSLES)
- TODO : for POSIX builds we should provide our own "null" audio backend if OpenAL/OpenSL not found by build script
- Eliminates a whole bunch of boilerplate setter/getter code in various places
- Accesses preferences directly from JSON data through custom json_parse.h API
- Improves code locality for Java menus/settings
- Breaking changes currently only tested on Linux desktop build =P
- Goal is to eventually eliminate most/many of the disparate getter/setter functions to allow better
modularity/scaling and platform portability
- Moves extra work off CPU/audio thread
- Prepares the way to possibly remove the vestigal intermediate indexed framebuffer and do direct RGBA_8888 writes
to XImage or OpenGL texture
- Prepares the ground for possible better emulation of video scanner hardware

- Differentiate between cpu_pause() when going to menu (and app is still foregrounded, and cpu_pauseBackground()
when a system backgrounding event has occurred.
- Destroy/free audio resources owned by CPU thread when background is requested, put CPU thread into waiting upon
pthread condition to resume.
- Mobile device now always signals pthread condition to force CPU thread resume from background
- Ensures various shutdown codepaths (interface, cpu/audio, main/video, ...) run on proper thread(s)
- Actually now runs the CloseAL() code
- Try to ensure all detached threads exit ... seems to help keep Valgrind happy =)
