coreaudio had names that are not conforming to QEMU codding style.
coreaudioVoiceOut also had some members that are prefixed with redundant
words like "output" or "audio".
Global names included "out" to tell they are specific to output devices,
but this rule was not completely enforced.
The frame size had three different names "frameSize", "bufferFrameSize",
and "frameCount".
Replace identifiers to fix these problems.
