pledge audio too
while for my particular use-case this has always worked with only "stdio recvfd", sio_open(3) mentions that if no further sio_open calls are made all pledges can be dropped except for "audio", so let's keep it.
remove the got_stop hack
now player_playnext has enough information to decide wheter to call player_senderr or player_sendeof.
change the log debug string for player_setup
now it includes all the params, not only the rate
don't assert IMSG_STOP
there's a small window of time where we could deliver a pause message and crash the player.
