sctp: delay calls to sk_data_ready() as much as possible

1st patch is a preparation for the 2nd. The idea is to not call
->sk_data_ready() for every data chunk processed while processing
packets but only once before releasing the socket.

v2: patchset re-checked, small changelog fixes
v3: on patch 2, make use of local vars to make it more readable
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Currently processing of multiple chunks in a single SCTP packet leads to
multiple calls to sk_data_ready, causing multiple wake up signals which
are costy and doesn't make it wake up any faster.

With this patch it will note that the wake up is pending and will do it
before leaving the state machine interpreter, latest place possible to
do it realiably and cleanly.

Note that sk_data_ready events are not dependent on asocs, unlike waking
up writers.

v2: series re-checked
v3: use local vars to cleanup the code, suggested by Jakub Sitnicki

It wastes space and gets worse as we add new flags, so convert bit-wide
flags to a bitfield.

Currently it already saves 4 bytes in sctp_sock, which are left as holes
in it for now. The whole struct needs packing, which should be done in
another patch.

Note that do_auto_asconf cannot be merged, as explained in the comment
before it.

bridge: support sending rntl info when we set attributes through sysfs/ioctl

This patchset is used to support sending rntl info to user in some places,
and ensure that whenever those attributes change internally or from sysfs,
that a netlink notification is sent out to listeners.

It also make some adjustment in bridge sysfs so that we can implement this
easily.

I've done some tests on this patchset, like:
[br_sysfs]
  1. change all the attribute values of br or brif:
  $ echo $value > /sys/class/net/br0/bridge/{*}
  $ echo $value > /sys/class/net/br0/brif/eth1/{*}

  2. meanwhile, on another terminal to observe the msg:
  $ bridge monitor

[br_ioctl]
  1. in bridge-utils package, do some changes in br_set, let brctl command
  use ioctl to set attribute:
         if ((ret = set_sysfs(path, value)) < 0) { -->
         if (1) {

  $ brctl set*

  2. meanwhile, on another terminal to observe the msg:
  $ bridge monitor

This test covers all the attributes that brctl and sysfs support to set.

Now when we change the attributes of bridge or br_port by netlink,
a relevant netlink notification will be sent, but if we change them
by ioctl or sysfs, no notification will be sent.

We should ensure that whenever those attributes change internally or from
sysfs/ioctl, that a netlink notification is sent out to listeners.

Also, NetworkManager will use this in the future to listen for out-of-band
bridge master attribute updates and incorporate them into the runtime
configuration.

The original tokenized iid support implemented via f53adae4 ("net: ipv6:
add tokenized interface identifier support") didn't allow for clearing a
device token as it was intended that this addressing mode was the only one
active for globally scoped IPv6 addresses. Later we relaxed that restriction
via 617fe29d ("net: ipv6: only invalidate previously tokenized addresses"),
and we should also allow for clearing tokens as there's no good reason why
it shouldn't be allowed.
