double free. Found and tested by Stefan Schmieta. OK markus@ mbalmer@

Use the proper in_ifscrub() / in_ifinit() calls for
address changes to generate routing messages.
The correct way to set the default route now
needs the -ifp option, e.g.
route add default -ifp pppoe0 0.0.0.1
Since the route is set right after bringing
the interface up, it still works w/out -ifp though.
Changes mostly from NetBSD.

m_prepend() should never be called directly, use M_PREPEND() instead.
Doing so simplifies the code. Tested by fkr@ and Paul de Weerd.

Instead, keep the proc pointer in it and put the selinfo on a list
in struct proc in selrecord. Then clean up the list when leaving
sys_select and sys_poll.

we had to put this workaround in since /etc/rc used to use the exit code
if "ifconfig pflog0" to decide wether we run on a kernel with pflog support.
rc has been fixed to explicitely create pflog0 when pf and pflogd are
enabled in November 2006, so now is the time to remove this compat hack.
pplz who haven't updated rc since 2006/11/16 lose pflogd. ok ryan theo

This provides a similar functionality as ARP balancing,
but also works for traffic that comes across routers.
IPv6 is supported as well.
The configuration scheme will change as soon we have sth better.
Also add support for changing the MAC address on carp(4)
interfaces. (code from mcbride)

Previously the descriptor was locked only after
an interface is set, leading to a race condition.

via TUNSIFINFO. ppp(8) was happily clearing the RUNNING flag and so all
incomming packets where dropped. Issue reported by irix <at> ukr <dot> net.
While there check that the mtu is in a valid range -- stolen from SIOCSIFMTU
case.

this allows an atomic read and reset counters, instead of read, reset in a
later ioctl and lose everything in between.
use the previously unused of pr->action. When it is set to PF_GET_CLR_CNTR,
the ioctl requires write permissions and counters are reset after they have
been copied out to userland.
obsoletes DIOCCLRRULECTRS, which only works for the main ruleset, but not
within anchors (yeah, that's how it all started)
ok dhartmei, mcbride and theo agree as well

ip6_dst (i'm bit skeptical about checksumming when the box is not the
final destination).
drop IPv6 jumbograms, as it could cause various funny symptoms due to
ip6_plen being 0 (yup, we should properly handle it instead).

- if the interface was auto-created by opening a /dev/tun* device it will
auto-destroy on close. This is comparable to ifconfig tun0 destroy and
will remove all routes and addresses associated with the interface.
- if the interface was created by ifconfig(8) or hostname.if(5) the interface
is persistent -- it is just marked as not running. Especially routes are no
longer removed when the interface is closed. This is useful for static
setups like the server side of a ssh vpn or static qemu session.
This behaviour is more logic then the half done cleanup that is currently done.

unicast reverse path forwarding (URPF) check drops packets coming in
on an interface other than that which holds the route back to the
packet's source address. this caused problems with routes bound to a
carp interface instead of the underlying interface. this diff
validates the underlying carpdev if the route is bound to a carp
interface.

P2P is commonly used in relation to peer to peer networks, PTP is used
in various protocols for layer 2 point to point links (ie., full
duplex ethernet links).
note that the newly added brconfig commands [-]p2p and [-]autop2p will
change to [-]ptp and [-]autoptp.
