Added new option 'type' to 'ip link show'
command which allows to filter devices by type:

    ip link show type bridge
    ip link show type vlan

Sometimes it's needed to have "ip address show" list only addresses
with certain flags not being set, e.g. in network scripts.
As an example one might want to exclude addresses in "tentative"
or "deprecated" state.

Support listing addresses with flags tentative, deprecated, dadfailed
not being set by prefixing the respective flag with a minus.

Remove all trailing whitespace and space before tabs.

Checking by SS_CLOSE state was remowed in:

    (45a4770b) ss: Remove checking SS_CLOSE state for packet and netlink

which is not really correct because now by default all sockets are seen
when do 'ss'.

Here is most correct fix which considers specified family.

To see netlink sockets:
    ss -A netlink

To see packet sockets:
    ss -A packet

And ss by default will show only connected/established sockets as it
was before all the time.

Replaced handling netlink messages by rtnl_dump_filter
from lib/libnetlink.c, also:

    - removed unused dump_fp arg;
    - added MAGIC_SEQ #define for 123456 seq id;
    - silently exit if ENOENT errno is caused for NETLINK_SOCK_DIAG proto
        in lib/libnetlink.c: rtnl_duml_filter_l(...) function. This fix
        was added in a3fd8e58 by Eric
        for misc/ss.c

Go back to kernel version of if_bridge.h and use patched
version of linux/in6.h and libc-compat.h

Needs to be built at runtime.

Now it is posible to filter by existing Netlink protos:

    ss -A netlink src uevent
    ss -A netlink src nft
    ss -A netlink src genl

Something like that maybe ?

This patch fixes the following issues which was introduced by me in commits:

    #1 (2dc85485) ss: Fixed broken output for Netlink 'Peer Address:Port' column
    ISSUE: Broken layout when all sockets are printed out

    #2 (eef43b50) ss: Identify more netlink protocol names
    ISSUE: Protocol id is not printed if 'numbers only' output was specified (-n)

Also aligned the width of the local/peer ports to be more wider.

I tested with a lot of option combinations (I may miss some test cases),
but layout seems to me better than the previous released version of iproute2/ss.

Adding in6.h breaks build with redefined values.

The issue was observed when IPv6 router broadcasted NDUSEROPT
messages which are not handled by monitor and caused printing
'Timestamps' w/o message because such kind of rtnl messages is not
handled by monitor.

As 'ip monitor' by default subscribes to the all mcast rtnl groups except
RTGRP_TC then all messages of these rtnl groups which are not handled by
monitor may cause such issues.

Fixed by subscribing by default to rtnl mcast groups which are
supported by 'ip monitor'.

This option was used only for 'ip link', but it can be useful to have it for
'ip address'. Thus it is possible to display link details and addresses with one
command.

Example:
$ ip -d a ls dev gre1
9: gre1@NONE: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1468 qdisc noqueue state UNKNOWN group default
    link/gre 10.16.0.249 peer 10.16.0.121 promiscuity 0
    gre remote 10.16.0.121 local 10.16.0.249 ttl inherit ikey 0.0.0.10 okey 0.0.0.10 icsum ocsum
    inet 192.168.0.249 peer 192.168.0.121/32 scope global gre1
       valid_lft forever preferred_lft forever
    inet6 fe80::5efe:a10:f9/64 scope link

I dont see a reason that packet and netlink states will be
printed only if SS_CLOSE state is set in filter, in that case
to print states of netlink or packet sockets it is needed to run:

    ss -A netlink state close

instead of:

    ss -A netlink
