Rename a header and some methods to make way for subsequent audio recording additions.

Renaming audio_output.h to audio_io.h as future patches will add audio recording code to this file.
Also renamed a couple of methods to make it clear that these are for audio playback/output and similar methods will be added for audio capture/recording soon.
BUG=none
TEST=no change in functionality.
