[Xenial,SRU] Xenial update to 4.4.82 stable release

Patch "packet: fix tp_reserve race in packet_set_ring" was skipped
because it is already applied for CVE-2017-1000111.

Skipped a whole bunch of changes, namely:

* revert "net: account for current skb length when
  deciding about UFO"
* revert "ipv4: Should use consistent conditional judgement for ip
  fragment in __ip_append_data and ip_finish_output"
* udp: consistently apply ufo or fragmentation
* ipv4: Should use consistent conditional judgement for ip fragment
  in __ip_append_data and ip_finish_output
* net: account for current skb length when deciding about UFO

I checked the resulting files net/ipv4/udp.c, net/ipv4/ip_output.c,
and net/ipv6/ip6_output.c from the 4.4.y tree and our Xenial tree. And
overall there is only one difference in the ip*_ouput.c files which come
from applying
* "udp: avoid ufo handling on IP payload compression packets" and
* "ipv6: Don't use ufo handling on later transformed packets" which
I picked as additional patches to be part of CVE-2017-1000112. And those
still look like fixes to valid issues (though probably not directly related
to the CVE). So I would suggest we stay at what we got right now.
