a0cadc83c6 Refactor timing locking behavior
- Do not start CPU thread until after splash screen
    - Insure that only CPU thread can actually create/destroy the audio interfaces

5f4bf6b1a7 Use single buffer queue callback for OpenSLES/Android
- OpenSLES Callback now performs simple mix of 2 sources (speaker and mockingboard)
    - Avoids multiple callbacks which was a performance penalty especially for low-end droids

60d32583ae Gets mockingboard playing with OpenSLES backend
- At ring buffer boundaries, we submit first the beginning of the samples buffer and then the end

f234de116f Refactor speaker system to prevent audio glitches and to support CPU automatic speed switching
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
