ss: use compact output for undetected screen width
This change fixes calculation of width in case user pipes the output.
SS output output works correctly when stdout is a terminal. When one
pipes the output, it tries to use 80 or 160 columns. That adds a
line-break if user has terminal width of 100 chars and output is of
the similar width. No width is assumed here.
To reproduce the issue, call
ss | less
and see every other line empty if your screen is between 80 and 160
columns wide.
This second version of the patch fixes screen_width being set to arbitrary
value.

For the 'set key' command, the given 'nodeid' parameter decides the
mode to be applied to the key, particularly:
- If NODEID is empty, the key is a 'cluster' key which will be used for
all message encryption/decryption from/to the node (i.e. both TX & RX).
The same key will be set in the other nodes.
- If NODEID is own node, the key is used for message encryption (TX)

rdma/sys.c: fix possible out-of-bound array access
netns_modes_str[] array has 2 elements, when netns_mode is 2,
condition (2 <= 2) will be true and `mode_str = netns_modes_str[2]'
will be executed, which will result in out-of-bound read.

ip: allow to use alternative names as handle
Extend ll_name_to_index() to get the index of a netdevice using
alternative interface name. Allow alternative long names to pass checks
in couple of ip link/addr commands.

lib/ll_map: cache alternative names
Alternative names are related to the "parent name". That means,
whenever ll_remember_index() is called to add/delete/update and it founds
the "parent name" im object by ifindex, processes related
alternative name im objects too. Put them in a list which holds the
relationship with the parent.

ipnetns: do not check netns NAME when -all is specified
When `-all' argument is specified netns runs cmd on all namespaces
and NAME is not used, but netns nevertheless checks if argv[1] is a
valid namespace name ignoring the fact that argv[1] contains cmd
and not NAME. This results in bug where user cannot specify
absolute path to command.
# ip -all netns exec /usr/bin/whoami
Invalid netns name "/usr/bin/whoami"
This forces user to have his command in PATH.
Solution is simply to not validate argv[1] when `-all' argument is
specified.
