This is another patch on the way towards a unified XFRM tunnel
encapsulation function.

This patch changes the value of props.header_len for IPCOMP to
exclude the IPCOMP header.  The reason is that the IPCOMP header
is added only if the packet is compressible.  That is, if the
size of the compressed payload plus the size of the IPCOMP header
is less than that of the original payload.

This means that the IPCOMP encapsulation does not impose any
overhead at all as far as the MTU is concerned.  The current
code incorrectly reduces the MTU by the size of the IPCOMP
header.

As a side-effect, this means that we don't have to move the
IP header around when IPCOMP is used.

This patch updates the network emulation packet scheduler.
	* name changed from delay to netem since it does more than just delay
	* Catalin's merged code to do packet reordering
	* uses a socket queue's directly rather than layering on qdisc(fifo)
	  because this is used in performance tests.
	* adds placeholder in API for future enhancements (rate and duplicate).

Packet with IPPROTO_HOPOPTS extended header isn't logged properly by
ip6t_LOG.c. It only prints PROTO=0 and nothing more, because
IPPROTO_HOPOPTS=0 and in this file 0 is used to indicate last header.
This patch fix it by using IPPROTO_NONE to indicate last header.

Just because gcc accepts [index] bar as
[index] = bar is no reason to make use of
that gross construct.

Also fully C99ify

This makes it not get sized/copied around to/from
userspace correctly.  The real crux of the problem
comes from the rtnetlink attribute copying line which
read:
	RTA_PUT(skb, TCA_STATS, (char*)&st->lock - (char*)st, st);
which is not necessarily sizeof(struct tc_stats) due
to alignment issues.

This way we will not forget to update XFRM_MSG_MAX in
the future.

This is another step towards the union of the tunnel mode encapsulation
between transforms.  As there are significant differences between the
tunnel encapsulation of IPv4 and IPv6, I'll be dealing with IPv4 only
for now.

This particular patch rearranges the code in ah_output to isolate the
tunnel mode encapsulation.

This patch makes netlink_connect() return the value of err instead of 0.
It doesn't actually make any difference since the current implementation
of netlink_autobind() never fails.  But since we went to all this trouble
to check the return status of autobind, might as well return the correct
value :)

While getting hands-on with netkit (www.netkit.org), a networking
simulation environment based on UML, it struck me that ifconfig wasn't
capable of calculating the proper broadcast address for a subnetted
interface. Some browsing through newsgroups and on the Debian package
site (nettools), showed that this leads to misconfigured interfaces and
a couple of bugreports on ifconfig.

Digging a bit deeper revealed that it actually is an issue with
SIOIFNETMASK. Once you bring up an interface with SIOIFADDR, a classfull
netmask and broadcast address is set (if applicable for the type of
interface), in order to get a properly configured interface. But if you
subnet the network using SIOIFNETMASK no proper broadcast address is
set. So you always have to calculate it yourself, obviously leading to
configuration errors.

This patch takes care of this. First of all it doesn't change
existing functionality, eg. a command like 'ifconfig eth0 192.168.1.1
netmask 255.255.255.240 broadcast 192.168.1.0' still works. But if you
omit the broadcast address, a proper 'all ones' broadcast address for the
subnet is set. 'ifconfig eth0 192.168.1.1 netmask 255.255.255.240' gives
you 'eth0 inet addr:192.168.1.1 Bcast:192.168.1.15 Mask:255.255.255.240'
and this should solve some real life problems.

As ->vm_private_data is used as a cursor for swapout of VM_NONLINEAR vmas,

For 32-bit, one quickly discovers that swapon() is not given an fd already
opened with O_LARGEFILE to act upon and the forcing of O_LARGEFILE for
64-bit is irrelevant, as the system call's argument is a path.  So this
patch manually forces it for swapon() and swapoff().
