* Soft restart:

- Allow NTP to reinitialize clock after the comm system
      in the first minute of uptime
    - Fix i2ptunnels not restarting
    - Increase minimum forward clock shift for soft restart
    - Reduce minimum backward clock shift for soft restart
    - Signal the I2CP client with a different message when restarting
    - I2CP client reconnects when receiving restart message
