Norman Feske 07669ac991 os: record-and-play session interfaces and mixer
- New session interfaces:
  - os/include/play_session   (for audio playing   / mic-input driver)
  - os/include/record_session (for audio recording / audio-output driver)
- Mixer at os/src/record_play_mixer providing both play and record services
- Simple waveform player at os/src/app/waveform_player
- Simple audio-signal capturing component at os/src/app/record_rom
- Simple oscilloscpe at gems/src/app/rom_osci (using record_rom)
- Simple test-audio_play for playing raw stereo f32 data

The _gems/run/waveform_player.run_ script illustrates the use of the new
components and interfaces.
