hostapd: backport support for sending debug messages to the syslog
It wasn't possible to read hostapd wpa_printf messages unless running hostapd manually. It was because hostapd was printing them using vprintf and not directly to the syslog. We were trying to workaround this problem by redirecting STDIN_FILENO and STDOUT_FILENO but it was working only for the initialization phase. As soon as hostapd did os_daemonize our solution stopped working. Please note despite the subject this change doesn't affect debug level messages only but just everything printed by hostapd with wpa_printf including MSG_ERROR-s. This makes it even more important as reading error messages can be quite useful for debugging. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

+Subject: [PATCH] hostapd: Add possibility to send debug messages to syslog
+
+We can only send module specific messages to syslog and not debug
+messages printed with wpa_printf. Add an extra command line parameter
+'-s' to allow it. The feature is enabled with compile flag
+CONFIG_DEBUG_SYSLOG as for wpa_supplicant and behaves in the same manner
+as the wpa_supplicant -s command line argument.
