OSS: handle device disconnects and reconnects (w/o needing a mpd restart)
Like the ALSA patches, this allows OSS devices to be disconnected during playback and MPD will be able to reopen and reuse them without restarting. git-svn-id: https://svn.musicpd.org/mpd/trunk@4366 09075e82-0dd4-0310-85a5-a0d7c8717e4f
