add support for brief output for link and addresses
This adds support for slightly less output than is normally provided by 'ip link show' and 'ip addr show'. This is a bit better when you have a host with lots of interfaces. Sample output: $ ip -br link show lo UNKNOWN 00:00:00:00:00:00 <LOOPBACK,UP,LOWER_UP> p2p1 UP 08:00:27:ee:0b:3b <BROADCAST,MULTICAST,UP,LOWER_UP> p7p1 UP 08:00:27:9d:62:9f <BROADCAST,MULTICAST,UP,LOWER_UP> p8p1 DOWN 08:00:27:dc:d8:ca <NO-CARRIER,BROADCAST,MULTICAST,UP> p9p1 UP 08:00:27:76:d9:75 <BROADCAST,MULTICAST,UP,LOWER_UP> p7p1.100@p7p1 UP 08:00:27:9d:62:9f <BROADCAST,MULTICAST,UP,LOWER_UP> $ ip -br -4 addr show lo UNKNOWN 127.0.0.1/8 p2p1 UP 192.168.56.2/24 p7p1 UP 70.0.0.1/24 p8p1 DOWN 80.0.0.1/24 p9p1 UP 10.0.5.15/24 p7p1.100@p7p1 UP 200.0.0.1/24 $ ip -br -6 addr show lo UNKNOWN ::1/128 p2p1 UP fe80::a00:27ff:feee:b3b/64 p7p1 UP 7000::1/8 fe80::a00:27ff:fe9d:629f/64 p8p1 DOWN 8000::1/8 p9p1 UP fe80::a00:27ff:fe76:d975/64 p7p1.100@p7p1 UP fe80::a00:27ff:fe9d:629f/64 $ ip -br addr show p7p1 p7p1 UP 70.0.0.1/24 7000::1/8 fe80::a00:27ff:fe9d:629f/64 v2: Now with color support! v3: Better field width estimation (except netdev names to keep output at a decent width) and whitespace fixup.
