Add rtcache_unref to release points of rtentry stemming from rtcache

In the MP-safe world, a rtentry stemming from a rtcache can be freed at any
points. So we need to protect rtentries somehow say by reference couting or
passive references. Regardless of the method, we need to call some release
function of a rtentry after using it.

The change adds a new function rtcache_unref to release a rtentry. At this
point, this function does nothing because for now we don't add a reference
to a rtentry when we get one from a rtcache. We will add something useful
in a further commit.

This change is a part of changes for MP-safe routing table. It is separated
to avoid one big change that makes difficult to debug by bisecting.

Patch posted to tech-net@
  http://mail-index.netbsd.org/tech-net/2015/03/15/msg005004.html

The choice to use a new structure sockaddr_big has been retained since
changing sockaddr_storage size would lead to unnecessary ABI change. The
use of the new structure does not preclude future work that increases
the size of sockaddr_storage and at that time sockaddr_big may be
trivially replaced.

Tested by mrg@ and myself, discussed with rmind@, posted to tech-net@

Make IPV4 mapped addresses able to do IPV4 multicast. Fixes needed:

	- allow binding to mapped v4 multicast addresses
	- define v4moptions, allow setting it via ioctl, pass it to ip_output,
	  free it when killing the pcb.

Ideally we would allow the IPV6 multicast setsockopts work on mapped addresses
too, but this is a lot more work and linux does not do it either.

Reduces the resources demanded by TCP sessions in TIME_WAIT-state using
methods called Vestigial Time-Wait (VTW) and Maximum Segment Lifetime
Truncation (MSLT).

MSLT and VTW were contributed by Coyote Point Systems, Inc.

Even after a TCP session enters the TIME_WAIT state, its corresponding
socket and protocol control blocks (PCBs) stick around until the TCP
Maximum Segment Lifetime (MSL) expires.  On a host whose workload
necessarily creates and closes down many TCP sockets, the sockets & PCBs
for TCP sessions in TIME_WAIT state amount to many megabytes of dead
weight in RAM.

Maximum Segment Lifetimes Truncation (MSLT) assigns each TCP session to
a class based on the nearness of the peer.  Corresponding to each class
is an MSL, and a session uses the MSL of its class.  The classes are
loopback (local host equals remote host), local (local host and remote
host are on the same link/subnet), and remote (local host and remote
host communicate via one or more gateways).  Classes corresponding to
nearer peers have lower MSLs by default: 2 seconds for loopback, 10
seconds for local, 60 seconds for remote.  Loopback and local sessions
expire more quickly when MSLT is used.

Vestigial Time-Wait (VTW) replaces a TIME_WAIT session's PCB/socket
dead weight with a compact representation of the session, called a
"vestigial PCB".  VTW data structures are designed to be very fast and
memory-efficient: for fast insertion and lookup of vestigial PCBs,
the PCBs are stored in a hash table that is designed to minimize the
number of cacheline visits per lookup/insertion.  The memory both
for vestigial PCBs and for elements of the PCB hashtable come from
fixed-size pools, and linked data structures exploit this to conserve
memory by representing references with a narrow index/offset from the
start of a pool instead of a pointer.  When space for new vestigial PCBs
runs out, VTW makes room by discarding old vestigial PCBs, oldest first.
VTW cooperates with MSLT.

It may help to think of VTW as a "FIN cache" by analogy to the SYN
cache.

A 2.8-GHz Pentium 4 running a test workload that creates TIME_WAIT
sessions as fast as it can is approximately 17% idle when VTW is active
versus 0% idle when VTW is inactive.  It has 103 megabytes more free RAM
when VTW is active (approximately 64k vestigial PCBs are created) than
when it is inactive.

Eliminate address family-specific route caches (struct route, struct
route_in6, struct route_iso), replacing all caches with a struct
route.

The principle benefit of this change is that all of the protocol
families can benefit from route cache-invalidation, which is
necessary for correct routing.  Route-cache invalidation fixes an
ancient PR, kern/3508, at long last; it fixes various other PRs,
also.

Discussions with and ideas from Joerg Sonnenberger influenced this
work tremendously.  Of course, all design oversights and bugs are
mine.

DETAILS

1 I added to each address family a pool of sockaddrs.  I have
  introduced routines for allocating, copying, and duplicating,
  and freeing sockaddrs:

        struct sockaddr *sockaddr_alloc(sa_family_t af, int flags);
        struct sockaddr *sockaddr_copy(struct sockaddr *dst,
                                       const struct sockaddr *src);
        struct sockaddr *sockaddr_dup(const struct sockaddr *src, int flags);
        void sockaddr_free(struct sockaddr *sa);

  sockaddr_alloc() returns either a sockaddr from the pool belonging
  to the specified family, or NULL if the pool is exhausted.  The
  returned sockaddr has the right size for that family; sa_family
  and sa_len fields are initialized to the family and sockaddr
  length---e.g., sa_family = AF_INET and sa_len = sizeof(struct
  sockaddr_in).  sockaddr_free() puts the given sockaddr back into
  its family's pool.

  sockaddr_dup() and sockaddr_copy() work analogously to strdup()
  and strcpy(), respectively.  sockaddr_copy() KASSERTs that the
  family of the destination and source sockaddrs are alike.

  The 'flags' argumet for sockaddr_alloc() and sockaddr_dup() is
  passed directly to pool_get(9).

2 I added routines for initializing sockaddrs in each address
  family, sockaddr_in_init(), sockaddr_in6_init(), sockaddr_iso_init(),
  etc.  They are fairly self-explanatory.

3 structs route_in6 and route_iso are no more.  All protocol families
  use struct route.  I have changed the route cache, 'struct route',
  so that it does not contain storage space for a sockaddr.  Instead,
  struct route points to a sockaddr coming from the pool the sockaddr
  belongs to.  I added a new method to struct route, rtcache_setdst(),
  for setting the cache destination:

        int rtcache_setdst(struct route *, const struct sockaddr *);

  rtcache_setdst() returns 0 on success, or ENOMEM if no memory is
  available to create the sockaddr storage.

  It is now possible for rtcache_getdst() to return NULL if, say,
  rtcache_setdst() failed.  I check the return value for NULL
  everywhere in the kernel.

4 Each routing domain (struct domain) has a list of live route
  caches, dom_rtcache.  rtflushall(sa_family_t af) looks up the
  domain indicated by 'af', walks the domain's list of route caches
  and invalidates each one.

KNF: de-__P, bzero -> memset, bcmp -> memcmp.  Remove extraneous
   parentheses in return statements.

Cosmetic: don't open-code TAILQ_FOREACH().

Cosmetic: change types of variables to avoid oodles of casts: in
   in6_src.c, avoid casts by changing several route_in6 pointers
   to struct route pointers.  Remove unnecessary casts to caddr_t
   elsewhere.

Pave the way for eliminating address family-specific route caches:
   soon, struct route will not embed a sockaddr, but it will hold
   a reference to an external sockaddr, instead.  We will set the
   destination sockaddr using rtcache_setdst().  (I created a stub
   for it, but it isn't used anywhere, yet.)  rtcache_free() will
   free the sockaddr.  I have extracted from rtcache_free() a helper
   subroutine, rtcache_clear().  rtcache_clear() will "forget" a
   cached route, but it will not forget the destination by releasing
   the sockaddr.  I use rtcache_clear() instead of rtcache_free()
   in rtcache_update(), because rtcache_update() is not supposed
   to forget the destination.

Constify:

   1 Introduce const accessor for route->ro_dst, rtcache_getdst().

   2 Constify the 'dst' argument to ifnet->if_output().  This
     led me to constify a lot of code called by output routines.

   3 Constify the sockaddr argument to protosw->pr_ctlinput.  This
     led me to constify a lot of code called by ctlinput routines.

   4 Introduce const macros for converting from a generic sockaddr
     to family-specific sockaddrs, e.g., sockaddr_in: satocsin6,
     satocsin, et cetera.

Pass the current process structure to in_pcbconnect() so that it can
pass it to in_pcbbind() so that can allocate a low numbered port
if setsockopt() has been used to set IP_PORTRANGE to IP_PORTRANGE_LOW.
While there, fail in_pcbconnect() if the in_pcbbind() fails - rather
than sending the request out from a port of zero.
This has been largely broken since the socket option was added in 1998.

IPv6 kernel code, based on KAME/NetBSD 1.4, SNAP kit 19990628.
(Sorry for a big commit, I can't separate this into several pieces...)
Pls check sys/netinet6/TODO and sys/netinet6/IMPLEMENTATION for details.

- sys/kern: do not assume single mbuf, accept chained mbuf on passing
  data from userland to kernel (or other way round).
- "midway" ATM card: ATM PVC pseudo device support, like those done in ALTQ
  package (ftp://ftp.csl.sony.co.jp/pub/kjc/).
- sys/netinet/tcp*: IPv4/v6 dual stack tcp support.
- sys/netinet/{ip6,icmp6}.h, sys/net/pfkeyv2.h: IETF document assumes those
  file to be there so we patch it up.
- sys/netinet: IPsec additions are here and there.
- sys/netinet6/*: most of IPv6 code sits here.
- sys/netkey: IPsec key management code
- dev/pci/pcidevs: regen

In my understanding no code here is subject to export control so it
should be safe.
