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

p2p1 UP 08:00:27:ee:0b:3b <BROADCAST,MULTICAST,UP,LOWER_UP>

v2: Now with color support!
v3: Better field width estimation (except netdev names to keep output at a
decent width) and whitespace fixup.

The previous man page fixup introduced a syntax error due to missing
opening bracket, which might crash some humanoid BNF parsers.

My previous patch 5950ba9 ("lib/namespace: don't leak fd in error case")
was a step in the wrong direction. Instead of closing the opened file
descriptor in error case only, follow a better approach here and close
the fd as soon as it is not used anymore. This way the inelegant goto
statements can be dropped, and the fd leak in non-error case is fixed as
well.

* Improve manual page synopsis and built-it help
* Use full subcommand names (e.g. 'address' and 'maddress')
* Specify when IPv4, IPv6 or both are affected
* Add lifetimes, home and nodad
* Remove any remaining excess spaces
Commit 43d29f7 substantially improves generated ip-address.8 instead of
ip-address.8.in and commit e419f2d removes the generated one losing the
improvements entirely. This commit recovers the lost changes, adapts
them to the current manual page and adds more man page and help
improvements.

* Add `can` to list of supported link types
* Document `addrgenmode`
* Document `link-netnsid`
* Document VLAN link type
* Improve VXLAN link type documentation
- Fix VXLAN srcport/dstport docs
- Document `udpcsum`, `udp6zerocsumtx` and `udp6zerocsumrx`
This was working before, but only if realloc a) succeeded and b) did not
move the buffer to a different location. ''**buf = **new_buf' then
writes the value of *new_buf's first field into that of *buf.

This is similar to command options corresponding to other NTF_* flags
already exposed to the user space (examples self/master).

There is no special reason to use the secure version of getenv, thus let's

After commit 8250bc9ff4 ("ss: Unify inet sockets output") raw sockets
are displayed as udp because dgram_show_line() is used for both and
thus IPPROTO_UDP is used for both so proto_name() returns "udp".
Fix this by checking dg_proto which is set according to the caller of
dgram_show_line().
