Once again get rid of busy waiting and use SIGSTOP for pause

OSS - Bithead USB => bad ALSA - Bithead USB => OK OSS - Onboard i8x0 => OK ALSA - Onboard i8x0 => OK bad - slow shutdown, pauses, dropped audio after pause/resume git-svn-id: https://svn.musicpd.org/mpd/trunk@6861 09075e82-0dd4-0310-85a5-a0d7c8717e4f
