Benjamin Poirier b262a9becb bridge: Fix output with empty vlan lists
Consider this configuration:

ip link add br0 type bridge
ip link add vx0 type vxlan dstport 4789 external
ip link set dev vx0 master br0
bridge vlan del vid 1 dev vx0
ip link add vx1 type vxlan dstport 4790 external
ip link set dev vx1 master br0

	root@vsid:/src/iproute2# ./bridge/bridge vlan
	port    vlan-id
	br0      1 PVID Egress Untagged

	vx0     None
	vx1      1 PVID Egress Untagged

	root@vsid:/src/iproute2#

Note the useless and inconsistent empty lines.

	root@vsid:/src/iproute2# ./bridge/bridge vlan tunnelshow
	port    vlan-id tunnel-id
	br0
	vx0     None
	vx1

What's the difference between "None" and ""?

	root@vsid:/src/iproute2# ./bridge/bridge -j -p vlan tunnelshow
	[ {
		"ifname": "br0",
		"tunnels": [ ]
	    },{
		"ifname": "vx1",
		"tunnels": [ ]
	    } ]

Why does vx0 appear in normal output and not json output?
Why output an empty list for br0 and vx1?

Fix these inconsistencies and avoid outputting entries with no values. This
makes the behavior consistent with other iproute2 commands, for example
`ip -6 addr`: if an interface doesn't have any ipv6 addresses, it is not
part of the listing.

Benjamin Poirier 1a500c78ae bridge: Fix tunnelshow json output
repeats for "vlan tunnelshow" what commit 0f36267485 ("bridge: fix vlan
show formatting") did for "vlan show". This fixes problems in json output.

Note that the resulting json output format of "vlan tunnelshow" is not the
same as the original, introduced in commit 8652eeb3ab ("bridge: vlan:
support for per vlan tunnel info"). Changes similar to the ones done for
"vlan show" in commit 0f36267485 ("bridge: fix vlan show formatting") are
carried over to "vlan tunnelshow".

Benjamin Poirier 955a20be02 bridge: Deduplicate vlan show functions
print_vlan() and print_vlan_tunnel() are almost identical copies, save for
a missing newline in the latter which leads to broken output of "vlan
tunnelshow" in normal mode.

Benjamin Poirier dfa13e2273 bridge: Fix vni printing
Since commit c7c1a1ef51 ("bridge: colorize output and use JSON print
library"), print_range() is used for vid (16bits) and vni. However, the
latter are 32bits so they get truncated. They got truncated even before
that commit though.
