/**
* @file
* @brief This handles debugging.
*
* @note log message is sent to syslog or stderr depending on --foreground
* command line argument
*
* @code
* Log1(priority, "text");
* log "text" with priority level priority
* Log2(priority, "text: %d", 1234);
* log "text: 1234"
* the format string can be anything printf() can understand
* Log3(priority, "text: %d %d", 1234, 5678);
* log "text: 1234 5678"
* the format string can be anything printf() can understand
* LogXxd(priority, msg, buffer, size);
* log "msg" + a hex dump of size bytes of buffer[]
* @endcode
