2f688f82da Incorporate new radix code from UCB. This fixes the orphaned mask bugs.
This submission was done by hand-applying FreeBSD local modifications on
top of the UCB code, rather than trying to patch the UCB code in on top
of the FreeBSD code due to the extensive changes.

cd02a0b741 Finally finish the cloning cleanup work by making sure that clones
go away whenever a clone's parent is changed, or a route is added in a
certain set of circumstances.

This also includes code to forbid setting a route's gateway to an
address which can only be reached through that route, thus (hopefully)
eliminating one class of cloning bottomless-recursion bugs.

5f679211e3 Fix slioctl(). It has to return -1 for ioctls that it doesn't know about
so that these ioctls can be handled by the calling layer(s).

Clean up the recently added code:
- include the appropriate header to declare an implicitly declared function.
- declare timeout functions correctly and remove numerous bogus casts that
  hid (but didn't fix) their incorrectness.

b4fff2ae1a Patch from Greg Ansley:
In rare cases, when the filter specified accesses an multi-byte value that
is split across mbuf's, the value loaded is incorrect.  And if you are very
unlucky (like me) it will index off the end of the mbuf and into an
unallocated page and panic the system.

If you look at the code you will discover the the index *k* is added to
the pointer *cp* and the used AGAIN as a subscript.

ca9301398c This sl enhancement helps to keep serial line (modem) connection alive.
It is common case when modem hangs with carier on but don't
receive anything from another side.
This thing commonly healed with hangup and redialing.
Enhancements below allows to determine when such action
is needed and inform attach program with SIGURG signal.
There two ioctls set: outfill and keepalive, used from both
sides of connection. Outfill repeatedly sends FRAME_END with
specified timeout (i.e. 40 seconds). It is needed to get input on
other side even if no user activity on slip line currently.
Keepalive checks FRAME_ENDs from other side, and if no one
got in specified timeout (i.e. 60 seconds, max modem retrain time),
send SIGURG to attach program.
I plan to add code to slattach to handle this thing too.

   o Fixing bug for Predictor-1 function.
   o Add new parameter that re-sent interval for set timeout commands.
   o Improving RTT (Round Trip Time) and reducing processor time.
     - Previous Timer service was using polling, and now using
       SIGALRM ;-)
     - A 0.94beta2 will not work correctly....

   -- Follows are additinal feature not including 0.94beta2
   o Support Proxy ARP

   o Marging common routine in CHAP/PAP.
   o Enhancing LCP/IPCP log information.
   o Support local Authfication connection on port 300x and tty.

       password in ppp.secret. if either ppp.secret file nor
       your hostname line don't exist, It will notify a message
       and working as same as previous version.(Backword compatibility)

18e1f1f110 route.c: keep track of where cloned routes come from, and make sure to
delete them when the ``parent'' goes away

route.h: add glue to track this to rtentry structure.  WARNING WILL ROBINSON!
This will be yet another incompatible change in your route-using binaries.
I apologize, but this was the only way to do it.  I took this opportunity
to increase the size of the metrics to what I believe will be the final
length for 2.1, so that when the T/TCP stuff is done, this won't happen
again.
