don't try to match the prev/next song; been broken since tx in load was added
originally i tried to match the previous or next song in the playing queue after a load command if the current song was not matched. The idea is ok-ish, but the implementation was broken and become a no-op after some recent refactoring in that area.
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 play_*() so that they return an integer
this will allow to remove the `got_stop' hack in player.c
drop now unused #include <sndio.h>
with the recent refactoring, sndio is only visible in player.c
fix argc check
argc can be -1 if we called noarg with argc=0, because optind is 1.
correctly handle arguments for sub-commands
things like "--" should be skipped etc, easier to rely on getopt(3).
