refactor the player_shouldstop/sio_write dance in a function

change the log debug string for player_setup now it includes all the params, not only the rate

fix player wrt unknown files

allow changing sample bit size

support setting the number of channels for flac and vorbis

implement `load' command

don't send eof if we got a IMSG_STOP

extra new line

typo

don't assert IMSG_STOP there's a small window of time where we could deliver a pause message and crash the player.

move player_sendeof outside player_playnext
