One step on improving the class api so that it can not be used incorrectly.
This also fixes the module owner issue with the dev files that happened when
the devt logic moved to the class core.

This patch changes the type of the third parameter 'length' of the 
raw_send_hdrinc() function from 'int' to 'size_t'.
This makes sense since this function is only ever called from one 
location, and the value passed as the third parameter in that location is 
itself of type size_t, so this makes the recieving functions parameter 
type match. Also, inside raw_send_hdrinc() the 'length' variable is 
used in comparisons with unsigned values and passed as parameter to 
functions expecting unsigned values (it's used in a single comparison with 
a signed value, but that one can never actually be negative so the patch 
also casts that one to size_t to stop gcc worrying, and it is passed in a 
single instance to memcpy_fromiovecend() which expects a signed int, but 
as far as I can see that's not a problem since the value of 'length' 
shouldn't ever exceed the value of a signed int).

This patch changes the type of the local variable 'i' in 
raw_probe_proto_opt() from 'int' to 'unsigned int'. The only use of 'i' in 
this function is as a counter in a for() loop and subsequent index into 
the msg->msg_iov[] array.
Since 'i' is compared in a loop to the unsigned variable msg->msg_iovlen 
gcc -W generates this warning : 

net/ipv4/raw.c:340: warning: comparison between signed and unsigned

Changing 'i' to unsigned silences this warning and is safe since the array 
index can never be negative anyway, so unsigned int is the logical type to 
use for 'i' and also enables a larger msg_iov[] array (but I don't know if 
that will ever matter).

This patch gets rid of the following gcc -W warning in net/ipv4/raw.c :

net/ipv4/raw.c:387: warning: comparison of unsigned expression < 0 is always false

Since 'len' is of type size_t it is unsigned and can thus never be <0, and 
since this is obvious from the function declaration just a few lines above 
I think it's ok to remove the pointless check for len<0.

This patch silences these two gcc -W warnings in net/ipv4/raw.c :

net/ipv4/raw.c:517: warning: signed and unsigned type in conditional expression
net/ipv4/raw.c:613: warning: signed and unsigned type in conditional expression

It doesn't change the behaviour of the code, simply writes the conditional 
expression with plain 'if()' syntax instead of '? :' , but since this 
breaks it into sepperate statements gcc no longer complains about having 
both a signed and unsigned value in the same conditional expression.

Implements an interface to be used by leaf qdiscs maintaining an internal
skb queue. The interface maintains a backlog in bytes additionaly
to the skb_queue_len() maintained by the queue itself. Relevant statistics
get incremented automatically. Every function comes in two variants, one
assuming Qdisc->q is used as queue and the second taking a sk_buff_head
as argument. Be aware that, if you use multiple queues, you still have to
maintain the Qdisc->q.qlen counter yourself.

This patch replaces the spin_lock_irqsave call on the receive queue
lock in SCTP with spin_lock_bh.  Despite the proliferation of
spin_lock_irqsave calls in this stack, it is only entered from the
IPv4/IPv6 stack and user space.  That is, it is never entered from
hardirq context.

The call in question is only called from recvmsg which means that
IRQs aren't disabled.  Therefore it is safe to replace it with
spin_lock_bh.

In light of my recent patch to net/ipv4/udp.c that replaced the
spin_lock_irq calls on the receive queue lock with spin_lock_bh,
here is a similar patch for all other occurences of spin_lock_irq
on receive/error queue locks in IPv4 and IPv6.

In these stacks, we know that they can only be entered from user
or softirq context.  Therefore it's safe to disable BH only.
