    protocol-native: fix bytes-to-usec conversion of "on-the-fly" data
    
    The on_the_fly_snapshot variable contains the amount of bytes that has
    been sent from the source IO thread to the main thread, but not yet
    pushed to the stream memblockq. The data is in the stream format, but
    the bytes-to-usec conversion used the source format, which caused random
    latency reporting errors.

    core: change configured_default_sink/source type to string
    
    This allows us to restore the default device properly when a
    hotpluggable device (e.g. a USB sound card) is set as the default, but
    unplugged temporarily. Previously we would forget that the unplugged
    device was ever set as the default, because we had to set
    configured_default_sink to NULL to avoid having a stale pa_sink pointer,
    and also because module-default-device-restore couldn't resolve the name
    of a currently-unplugged device to a pa_sink pointer.
