BF/ENH: include [PID] into logging msgs, remove indentation from syslog messages

Otherwise leads to incorrect parsing of the log messages by syslog(-ng). See
http://bugs.debian.org/730202

I also removed %(levelname)-6s from syslog messages completely since they are
passed to the syslog and it is up to the configuration/admin to decide include
levels into the messages or not (I have checked that at least debug level indeed
goes to /var/log/debug)
