Cleaned up the logging command-line option variables:
- renamed VG_(logging_to_filedes) as VG_(logging_to_socket), which is
  clearer
- no longer exporting clo_log_to, which avoids the confusion about whether
  it or VG_(logging_to_socket) actually controls where output goes
- couple of other minor cleanups
