18cd17b80a Now that sppp announces address additions and removals with state 
flags, we no longer need the custom sppp code to detect if we are
connected or not.

Add commentary on if we really need to handle RTM_DELADDR only when
detached.

8248001c7f Use unsigned, not signed, int for shifting 1 left until zero. 
Signed shift into sign bit and beyond is undefined behaviour.

bbdb057767 Just ignore a bunch of well-known routing socket messages ifwatchd 
doesn't care about to make verbose mode less noisy.  When it does print
an unknown header type, also say which one it doesn't like.

59ca47f545 In the initial interface scan at start time, query the link status of 
the interfaces and call the CARRIER script if a link is already there.
This allows me to boot my notebook with the cable pluged and
fixes PR bin/26830.

25943be498 Use the new SPPPGETSTATUSNCP ioctl, if supported, to avoid reporting 
intermitent changes on "volatile" interfaces based on if_spppsubr.c.
This interfaces used to cause ifwatchd to call the up and down scripts
with 0.0.0.0 addresses between entering PPP phase network and IPCP
completition.

5005fdb656 Run "arrival" scripts too in the inital pass on startup. 
Open the routing socket before this pass to close a small window where
we would miss messages at startup (and get state kept by the scripts
out of sync).

7b6f872d11 Add, #ifdef SPPP_IF_SUPPORT, special case treatment for sys/net/if_spppsubr.c 
based interfaces. Note: all other interface types work the same as before,
and no names are hardcoded.

When a if_spppsubr.c based interface is marked IFF_UP, but has not yet
reached phase NETWORK (i.e. it didn't connect yet or authentication has not
yet completed) do not call the ip-up script for it on the initial pass
over all IFF_UP interfaces.

This fixes a race condition on startup when ip-up/ip-down are statefull
and need to be called pairwise (for example if ip-up adds and ip-down
removes a default route).

0f93714245 Pass the remote address (or broadcast addres) to the up/down scripts as 
well. This is very usefull for setting up the right routes ;-)

Thanks to Bjoern Labitzke for pointing out this missing feature.

c8b09ee080 New utility: ifwatchd. 
Monitors the routing socket for address changes of autonomous (kernel only)
interfaces (like PPPoE) and runs up/down scripts similar to what pppd
does for its interfaces.
