1e90474c37 [NET_SCHED]: Convert packet schedulers from rtnetlink to new netlink API
Convert packet schedulers to use the netlink API. Unfortunately a gradual
conversion is not possible without breaking compilation in the middle or
adding lots of casts, so this patch converts them all in one step. The
patch has been mostly generated automatically with some minor edits to
at least allow seperate conversion of classifiers and actions.

9bb268ed7c [NETFILTER]: xt_TOS: Change semantic of mask value
This patch changes the behavior of xt_TOS v1 so that the mask value
the user supplies means "zero out these bits" rather than "keep these
bits". This is more easy on the user, as (I would assume) people keep
more bits than zeroing, so, an example:

	Action:     Set bit 0x01.
    	before (&): iptables -j TOS --set-tos 0x01/0xFE
    	after (&~): iptables -j TOS --set-tos 0x01/0x01

This is not too "tragic" with xt_TOS, but where larger fields are used
(e.g. proposed xt_MARK v2), `--set-xmar 0x01/0x01` vs. `--set-xmark
0x01/0xFFFFFFFE` really makes a difference. Other target(!) modules,
such as xt_TPROXY also use &~ rather than &, so let's get to a common
ground.

(Since xt_TOS has not yet left the development tree en direction to
mainline, the semantic can be changed as proposed without breaking
iptables.)

8ce22fcab4 [NETFILTER]: Remove some EXPERIMENTAL dependencies
Most of the netfilter modules are not considered experimental anymore,
the only ones I want to keep marked as EXPERIMENTAL are:

- TCPOPTSTRIP target, which is brand new.

- SANE helper, which is quite new.

- CLUSTERIP target, which I believe hasn't had much testing despite
  being in the kernel for quite a long time.

- SCTP match and conntrack protocol, which are a mess and need to
  be reviewed and cleaned up before I would trust them.

b3fd3ffe39 [NETFILTER]: Use the ctl paths instead of hand-made analogue
The conntracks subsystem has a similar infrastructure
to maintain ctl_paths, but since we already have it
on the generic level, I think it's OK to switch to
using it.

So, basically, this patch just replaces the ctl_table-s
with ctl_path-s, nf_register_sysctl_table with
register_sysctl_paths() and removes no longer needed code.

After this the net/netfilter/nf_sysctl.c file contains
the paths only.
