All right. So, built time configuration CONFIG_NO_DEBUG should remove
all debugging code, including command line options pertaining to
debug.

Debug to stdout or stderr but not both. Actually, it would me more
politically right to use stderr for debug.
But we need some defaults.

* when running in foreground and '-d' command line option, debug
  messages go to stderr; if '-s' option is also present on the command
  line, debug messages will go to syslog too
* when running in background, and '-d' command line option, debug
  messages go to syslog only
* when '-d' command line option is not used, no debug messages will be
  generated

IMHO, I see some need for a few syslog messages when wpa_supplicant is
daemonized, like: started, authenticated, failed, stopped. What do you
think?

It is particulary useful to get syslog messages when running
wpa_supplicant on embeded systems.
