"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
<net/if_arp.h>.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

I think the new wordings are more clear and could save some support
questions.

This is mainly cosmetic for 'arp' and 'netstat -r'.

The NetBSD version of this patch (see NetBSD PR kern/2381) has this change
already. This should close our PR kern/1140 .

gcc only inlines memcpy()'s whose count is constant and didn't inline
these. I want memcpy() in the kernel go away so that it's obvious that
it doesn't need to be optimized. Now it is only used for one struct
copy in si.c.
Get rid of ac->ac_ipaddr and arpwhohas() since they assume that
an interface has only one address.

others: start to populate the link-layer branch of the net mib, by
moving ARP to its proper place. (ARP is not a protocol family, it's an
interface layer between a medium-access layer and a protocol family.)
sysctl(8) needs to be taught about the structure of this branch, unless
Poul-Henning implements dynamic MIB exploration soon.
Add five sysctl variables that you should probably never tweak.

(It's net.arp because arp isn't limited to inet, though our present
implementation surely is).
we're at it, eliminate obsolete exposure of `struct llinfo_arp' to
the world. (This dates back to when ARP entries were not stored in
the routing table, and there was no other way for the `arp' program
to read the whole table than to grovel around in /dev/kmem.)
there may even be LKMs.) Also, change the internal name of `unixdomain'
to `localdomain' since AF_LOCAL is now the preferred name of this family.
Declare netisr correctly and in the right place.

like there may be a number of incipient bugs in this code.
Also, get ready for the time when all IP gateway routes are cloning, which
is necessary to keep proper TCP statistics.
a FreeBSD box to do proxy ARP as easily as most commercial routers do,
without messing around with (potentially variable) Ethernet addresses.
This code is really quite simple; I'm not at all sure why it wasn't
implemented in 4.4.
It might be worth stealing an interface flag (maybe IFF_LINK1) to use for
finer-grained control over which interfaces get proxy treatment. For the
moment, it's all or nothing.
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.
NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.
