    sink, source: Add a mode to avoid resampling if possible

    This adds an "avoid-resampling" option to daemon.conf that makes the
    daemon try to use the stream sample rate if possible (the device needs
    to support it, which currently only ALSA does), and there should not be
    any other stream connected).

    This should enable some of the "audiophile" use-cases where users wish
    to play high sample rate audio files without resampling.

    We still will do conversion if sample formats don't match, though. This
    means that if you want to play 96 kHz/24 bit audio without any
    modification the default format will need to be set to be 24-bit as
    well. This will force all streams to be upconverted, which, other than
    the wasted resources, should be relatively harmless.
