Show IP addresses in cli/list output

[gronke]

Currently the output of cli/list does not print useful information about jail's network configuration or status.

Requirements

• the cli/list table cell is multiline when there are multiple IP addresses shown
• When a jail is stopped
  • IP4.ADDR shows the value configured for ip4_addr in JailConfig
  • IP6.ADDR shows the value configured for ip6_addr in JailConfig
• Whan a jail is started
  • IP4.ADDR shows a list of the real jail's IPv4 addresses
  • IP6.ADDR shows a list of the real jail's IPv6 addresses
  • marks a listed IP address with a * when it was automatically assigned (with DHCP or Router Advertisement)
