Fix the problem of songs not advancing without client activity The select() in the main event loop blocks now (saving us many unnecessary wakeups). This interacted badly with the threads that were trying to wakeup the main task via pthread_cond_signal() since the main task was not blocked on a condition variable, but on select(). So now if we detect a need to wakeup the player, we write to a pipe which select() is watching instead of blindly calling pthread_cond_signal(). git-svn-id: https://svn.musicpd.org/mpd/trunk@7347 09075e82-0dd4-0310-85a5-a0d7c8717e4f

added prefix to header macros "LOG_H" is a macro which is also used by ffmpeg/log.h. This is ffmpeg's fault, because short macros should be reserved for applications, but since it's always a good idea to choose prefixed macro names, even for applications, we are going to do that in MPD.

main_notify: define main_task so we can use it for assertions It'll be easier to keep track of what code runs in what task/thread this way.
