- Futher disentangle display, interface, and video backends
- Backend video owns the staging/intermediate framebuffer for now
- Add the beginnings of display update callbacks
- 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

Squashed commit of the following:
REFACTOR : fix comments, logging, and rename some variables
REFACTOR : fix up some commentary, clean deadc0de
REFACTOR : mostly fix all the audio glitches
- amplitudes of samples are gradually shifted to zero when speaker has fallen silent
- simplifies speaker state machine
- fullspeed mode only enqueues quiet samples
REFACTOR : fix up a number of other functions and comments
REFACTOR : clean up code to submit normal speed wave buffer to OpenAL
Move some initializations to the cpu_thread()
REFACTOR : properly reset the speaker cycles access counter so we don't underflow and assert
REFACTOR : should never get a split buffer from our soundcore implementation
Fix warning from gcc ... static array size needs to be computed from integer values
REFACTOR : gcc (but not clang) complains about these, so just make them preprocessor defines
REFACTOR : use unsigned long long because we don't actually care that this counter is 64bit
REFACTOR : remainder_buffer and miscellaneous tweaks
- Adds implementation commentary to document remainder_buffer purpose
- Also adds sample average for square wave boundary in case where remainder_buffer not used (whole-sample boundary)
- Variable renaming and code shuffling
REFACTOR : do not dynamically alloc remainder buffer
- Never attribute to cache-coherancy bugs what is a simple thread race =P
REFACTOR : comments and whitespace
REFACTOR : rename public speaker API functions
REFACTOR : clean up public speaker API
REFACTOR : tabs to spaces
REFACTOR : moar deadc0de clean up and renaming
REFACTOR : remove deadc0de paths from soundcore
REFACTOR : fully excise soundtype stuff now that we only support soundcard output
Move a file static to function scope
REFACTOR : rename more variables and remove deadc0de
REFACTOR : samples_buffer naming and change to explict int16_t
REFACTOR : removed deadc0de and shuffled code locations
REFACTOR : remainder buffer naming and clarify type
REFACTOR : move joystick timing to VM module and remove header visibility
REFACTOR : clarify speaker variable name
REFACTOR : clarify cycle counting codepaths
REFACTOR : VBL/timing interfaces
- eliminates passing around a common global
REFACTOR : names and comments
HACK around volume issue
REFACTOR : rename speaker feedback variable
REFACTOR : rename global total cycle count
REFACTOR : rename a constant
Fix test builds
REFACTOR: rename to is_fullspeed
REFACTOR : local variable naming changes
REFACTOR : migrate cycle timing variables to correct location and remove header visibility
Allow fullspeed codepath to update speaker
REFACTOR : remove deadc0de paths in prep for cleanup
REFACTOR : speaker now manages its own VM entry point
- Attempts to be byte-stream compatible with how AppleWin handles DOS-order, ProDOS-order, and NIB images
- Adds support for ProDOS-order images
- First cut at VBL support: (//e FlappyBird boots now!)
* TYPE : send debugger console through to the machine
* LOAD : send textfile through to the same mechanism
* FBSHA1 : get a SHA1 value of the current machine framebuffer
* better CPU stepping functionality
