changed from daemon.info to a new option default_syslog that
uses daemon.info as default and additionally parses syslog
messages for info about facility,priority and uses this info
if available.

Some deamons/etc that log messages to syslog do not specify facility.level
in their messages. The logger is configured to parse the message looking
for facility.level (option: --prio-prefix). If the message does not include
If no facility.priority is specified, the logger will use the one specified
after -p, this is now provided. For example, PPSi does not specify
facility.priority in messages (hopefully, this will change), without
"-p daemon.info", it was reported as user.info. If user wishes to,
he/she can override. This is the default config

calibration is finished.

Setting the options to force dot-config/IP over DHCP can
be dangerous. Until now, the switch would wait endlessly

This commit introduces a way to escape the loop. This can
be done by connecting to the back UART and pressing any
key.

Now it represents the overall status of system clock:
- verification with NTP time
- leap seconds file
