Emmanouil Papadeas c36460060e
Further refactoring to AudioDriver implementations after .
- Rename all instances of `capture_start()` and `capture_end()` to their new
  names. Fixes .
- More internal renames to match what was started in .
- Use `override` consistently so that such refactoring bugs can be caught.
- Harmonize the order of definition of the overridden virtual methods in each
  audio driver.
- Harmonize prototype for `set_output_device` and `set_input_device`.
