The ma_audio_buffer object is used for storing raw audio data in memory
and reading from it like any other data source. It supports flexible
memory management, reading, seeking, memory mapping and looping.

See documentation under "Audio Buffers" for a detailed description.

This addresses some clipping issues when accumulating.

ma_zero_pcm_frames() will be removed in version 0.11.

This adds the following:
  * MA_VERSION_MINOR
  * MA_VERSION_MAJOR
  * MA_VERSION_REVISION
  * MA_VERSION_STRING
  * ma_version()
  * ma_version_string()
