notify: more cleanups, add error checking for pipe errors
Don't bother initializing the junk buffer, we really don't care. The array was also unnecessary and ugly. Also, avoid returning the byte count we read/wrote since it unnecessarily exposes internal details of the implementation to the callers. git-svn-id: https://svn.musicpd.org/mpd/trunk@7219 09075e82-0dd4-0310-85a5-a0d7c8717e4f
