Handle the helper assignment centrally, which allows to perform the

[NET_SCHED]: Fix endless loops (part 5): netem/tbf/hfsc ->requeue failures
When peeking at the next packet in a child qdisc by calling dequeue/requeue,
the upper qdisc qlen counter may get out of sync in case the requeue fails.
The qdisc and the child qdisc both have their counter decremented, but since
no packet is given to the upper qdisc it won't decrement its counter itself.
requeue should not fail, so this is mostly for "correctness".

[NET_SCHED]: Fix endless loops caused by inaccurate qlen counters (part 1)
There are multiple problems related to qlen adjustment that can lead
to an upper qdisc getting out of sync with the real number of packets
queued, leading to endless dequeueing attempts by the upper layer code.
All qdiscs must maintain an accurate q.qlen counter. There are basically
two groups of operations affecting the qlen: operations that propagate
down the tree (enqueue, dequeue, requeue, drop, reset) beginning at the
root qdisc and operations only affecting a subtree or single qdisc
(change, graft, delete class). Since qlen changes during operations from
the second group don't propagate to ancestor qdiscs, their qlen values
become desynchronized.
This patch adds a function to propagate qlen changes up the qdisc tree,
optionally calling a callback function to perform qdisc-internal
maintenance when the child qdisc becomes empty. The follow-up patches
will convert all qdiscs to use this function where necessary.

This patch also has a nice side effect in that all of the security attributes

[NETFILTER]: sip conntrack: better NAT handling
The NAT handling of the SIP helper has a few problems:
- Request headers are only mangled in the reply direction, From/To headers
not at all, which can lead to authentication failures with DNAT in case
the authentication domain is the IP address
- Contact headers in responses are only mangled for REGISTER responses
- Headers may be mangled even though they contain addresses not
participating in the connection, like alternative addresses
- Packets are droppen when domain names are used where the helper expects
IP addresses
This patch takes a different approach, instead of fixed rules what field
to mangle to what content, it adds symetric mapping of From/To/Via/Contact
headers, which allows to deal properly with echoed addresses in responses
and foreign addresses not belonging to the connection.
