    svc - Implement more features
    * All stdout/stderr output now goes to a pipe and a pipe buffering thread
      to read it into a circular buffer as well as write it to the log file.
      The program is now able to retain ~8KB worth of output in its circular
      buffer whether there is a log file attached to the service or not.
    * When /dev/null is specified as the log file, short-cut the descriptor to -1
      instead of actually writing to /dev/null.
    * log, logf, and tailf directives now work.
    * Properly escape '.' on a line by itself for all buffered data dumped
      over a remote link (allowing logs to contain our command response
    * Implement -f (foreground option) and clean-up descriptor initialization.
    * Implement -s (sync on exit)
