Merge branch 'ip-Use-rb-trees-for-IP-frag-queue'

Peter Oskolkov says:

====================
ip: Use rb trees for IP frag queue.

This patchset
 * changes IPv4 defrag behavior to match that of IPv6: overlapping
   fragments now cause the whole IP datagram to be discarded (suggested
   by David Miller): there are no legitimate use cases for overlapping
   fragments;
 * changes IPv4 defrag queue from a list to a rb tree (suggested
   by Eric Dumazet): this change removes a potential attach vector.

Upcoming patches will contain similar changes for IPv6 frag queue,
as well as a comprehensive IP defrag self-test (temporarily delayed).
