Not tested on the if_sr, if_cx and if_ar drivers, but

Any users of these drivers (or even better: donors
of hardware for them) please contact phk@freebsd.org

for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.
These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

FreeBSD repository version of this file and the isdn4bsd version,
adopt those changes from the i4b version that make this file
BSD-version independent. I attempted to avoid uglifying this file too
much, thus deviated a little from the i4b version (and hope they will
adopt the changes, too).
The diffs mostly concentrate on:
. #include differences between the systems
. different callout handling between FreeBSD vs. Net/OpenBSD
. interface naming (Net/OpenBSD store the ASCII name including the
unit # in struct ifnet, FreeBSD only the name)
. use of random() in FreeBSD vs. time-based pseudo-randomization in
Net/OpenBSD (for loopback detection ad CHAP challenges -- i
assume at least OpenBSD could also benefit from random(), but that's
the way i've got this file)
. interface address list elements are named a little differently
between FreeBSD and Net/OpenBSD
I attempted to segregate those compat fixes from other code fixes and
enhancements.

* Figure out UTC relative to boottime. Four new functions provide
time relative to boottime.
* move "runtime" into struct proc. This helps fix the calcru()
problem in SMP.
* kill mono_time.
* add timespec{add|sub|cmp} macros to time.h. (XXX: These may change!)
* nanosleep, select & poll takes long sleeps one day at a time

"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.
Most uses of time.tv_sec now uses the new variable time_second instead.
gettime() changed to getmicrotime(0.
Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).
A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.
Add a new nfs_curusec() function.
Mark a couple of bogosities involving the now disappeard time variable.
Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.
Change profiling in ncr.c to use ticks instead of time. Resolution is
the same.
Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

This will not make any of object files that LINT create change; there
might be differences with INET disabled, but hardly anything compiled
before without INET anyway. Now the 'obvious' things will give a
proper error if compiled without inet - ipx_ip, ipfw, tcp_debug. The
only thing that _should_ work (but can't be made to compile reasonably
easily) is sppp :-(
This commit move struct arpcom from <netinet/if_ether.h> to

In sppp_chap_input:
1) in the CHAP_CHALLENGE case don't output the peer's name if it is not
what we expected (DEBUG) since it will be printed out in the course
of events anyway.
2) in the CHAP_SUCCESS case test whether the peer is required to
authenticate himself [(sp->lcp.opts & (1 << LCP_OPT_AUTH_PROTO))],
otherwise the state machine may never switch into the network state.
I saw this case against 2 different ISPs; they never bothered to
authenticate themselves to me.
In sppp_pap_input:
in the PAP_ACK case do the same as in 2) above for the same reason.
The #ifdef IPXIP in netipx/ipx_if.h is OK (used from ipx_usrreq.c and
ifconfig.c only).
I also fixed a typo IPXTUNNEL -> IPTUNNEL (and #ifdef'ed out the code
inside, as it never could have compiled - doh.)

this to provide PPP support for the BISDN project (right now).
Unfortunatley, while the existing API was almost up to the point, i
needed one minor API change in order to decouple the this-layer-
started and this-layer-finished actions from the respective Up and
Down events of the lower layer. This requires two additional lines in
the attach routines of all existing lower layer interface drivers that
are using syncPPP (shortcutting these actions and events). Apart from
this, i believe i didn't change the API of all this, so everything
should plug in without too many hassles. Please report if i broke
something in the existing drivers.
For a list of features (including new ones like dial-on-demand), and
things still to be done, please refer to the man page i'll commit asap.

it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..

rtalloc1() to allow for any interface flags to be ignored; currently
this is only useful for RTF_PRCLONING. Get rid of rt_prflags and re-unite

This also adds a new interface parameter, `ifi_physical', which will
eventually replace IFF_ALTPHYS as the mechanism for specifying the
