9b703b1455 Eradicate the variable "time" from the kernel, using various measures.
"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.

bcae2312af Make INET a proper option.
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>.

8b06260475 Set the rmx.rmx_expire to 0 when creating fake ethernet addresses for the
broadcast and multicast routes, otherwise they will be expired by
arptimeout after a few minutes, reverting to " (incomplete)". This makes
the work done by rev 1.27 stay around until the route itself is deleted.
This is mainly cosmetic for 'arp' and 'netstat -r'.

The NetBSD version of this patch (see NetBSD PR kern/2381) has this change

11d257651d Changed some memcpy()'s back to bcopy()'s.
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.

3bc72fd215 in_proto.c: spell ``Internet'' right and put whitespace after commas.
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.)

Poul-Henning implements dynamic MIB exploration soon.

91aa19bcd7 Convert ARP to use queue.h macros rather than insque/remque. While
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.)

9ce9e24f39 Implement full proxy ARP, gated on option ARP_PROXYALL. This allows
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.

f9fc827448 Fix up some sloppy coding practices:
- 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.
