ipstats_stat_desc_show_xstats() operates by first parsing the attribute
stream into a type-indexed table, and then accessing the right attribute.
But bridge VLAN stats are given as several BRIDGE_XSTATS_VLAN attributes,
one per VLAN. With the above approach to parsing, only one of these
attributes would be shown. Instead, iterate the stream of attributes and
call the show_cb for each one with a matching type.

`ip stats' displays a range of bridge_slave-related statistics, but not
the VLAN stats. `bridge vlan' actually has code to show these. Extract the
code to libutil so that it can be reused between the bridge and ip stats
tools.
Rename them reasonably so as not to litter the global namespace.

Add support for displaying bridge VLAN statistics in `ip stats'.
Reuse the existing `bridge vlan' display and JSON format:
# ip stats show dev v2 group xstats_slave subgroup bridge suite vlan
2: v2: group xstats_slave subgroup bridge suite vlan
10
RX: 3376 bytes 50 packets
TX: 2824 bytes 44 packets
20
RX: 684 bytes 7 packets
TX: 0 bytes 0 packets
# ip -j -p stats show dev v2 group xstats_slave subgroup bridge suite vlan
[ {
"ifindex": 2,
"ifname": "v2",
"group": "xstats_slave",
"subgroup": "bridge",
"suite": "vlan",
"vlans": [ {
"vid": 10,
"rx_bytes": 3376,
"rx_packets": 50,

},{
"vid": 20,
"rx_bytes": 684,
"rx_packets": 7,
"tx_bytes": 0,
"tx_packets": 0
} ]
} ]
Similarly for the master stats:
# ip stats show dev br1 group xstats subgroup bridge suite vlan
211: br1: group xstats subgroup bridge suite vlan
10
RX: 3376 bytes 50 packets
TX: 2824 bytes 44 packets
20
RX: 684 bytes 7 packets
TX: 0 bytes 0 packets
# ip -j -p stats show dev br1 group xstats subgroup bridge suite vlan
[ {
"ifindex": 211,
"ifname": "br1",
"group": "xstats",
"subgroup": "bridge",
"suite": "vlan",

"vid": 10,
"flags": [ ],
"rx_bytes": 3376,
"rx_packets": 50,

},{
"vid": 20,
"flags": [ ],
"rx_bytes": 684,
"rx_packets": 7,

"tx_packets": 0
} ]
} ]

Notes:
v3:
- Add man page coverage.
- Order the VLAN suite at the end in both master and slave subgroups.
- Retain Nik's Acked-by for these.
v2:
- Add the master stats as well.
