0de32b854f Fall back to kvm interface for protocols that do not yet 
offer a sysctl interface. Fixes PR bin/36210.

65305bdc98 Good intentions are still intentions. If we can't open kvm, but we still 
have sysctl, it's still not enough for -P. A groveler is a groveler is
a groveler.

On a different note, this code needs a rewrite.

32f8a691e7 - Back to using kvm if we have access to it, since the sysctl stats do not 
yet support all the fields we need.
- Don't core-dump if we could not open the kvm file.

5d7aa1a613 Make netstat use sysctl when dumping routing tables/stats. 
Heavily based on similar code from Claudio Jeker (at OpenBSD).

While here, fix inet/inet6 sysctl stuff commited previously to
actually work, and some other nits to make netstat more sysctl
friendly.

One step closer to losing setgid kmem on this one...

d65009381e Request process information using sysctl(3) and not kvm(3) since bpf(4)

66daeed445 Implemented the userland part of the BPF statistics and BPF peers, 
net.bpf.stats and net.bpf.peers sysctls respectively. netstat(1) now
has an additional syntax:
	netstat [-s] [-B] [-I Interface]

Only the super user can see a list of BPF peers with the following command:
# netstat -B
Active BPF peers
PID     Int     Recv     Drop     Capt     Flags  Bufsize  Comm
4941    lo0     0        0        0        I--S-  262144   tcpdump
252     ex0     19668    0        5        I-RS-  32768    dhclient

And every user can see the BPF statistics with:
$ netstat -s -B
bpf:
        19669 total packets received
        5 total packets captured
        0 total packets dropped

This idea came from FreeBSD (Christian S.J. Peron) but, currently, they
doen't have a userland utility in the base system to read the sysctls.

f8aeaf6223 Fix two stupid bugs I introduced with stats for fast-ipsec: 
1. Pass the caller-supplied protocol name down through ipsec_switch().

2. Remove my poor attempt to print fast-ipsec stats automagically for
`netstat -s'.  The previous code would print (fast)IPsec per-protocol
stats even for 'netstat', which is just wrong.

A better fix would be to enumerate the sub-"protocols" under IPsec;
but first lets fix the broken behaviour now, for a pullup to 2.0.

85b3ba5bf1 Redo net.inet.* sysctl subtree for fast-ipsec from scratch. 
Attach FAST-IPSEC statistics with 64-bit counters to new sysctl MIB.
Rework netstat to show FAST_IPSEC statistics, via sysctl,  for
netstat -p ipsec.

New kernel files:
	sys/netipsec/Makefile		(new file; install *_var.h includes)
	sys/netipsec/ipsec_var.h	(new 64-bit mib counter struct)

Changed kernel files:
	sys/Makefile			(recurse into sys/netipsec/)
	sys/netinet/in.h		(fake IP_PROTO name for fast_ipsec
					sysctl subtree.)
	sys/netipsec/ipsec.h		(minimal userspace inclusion)
	sys/netipsec/ipsec_osdep.h	(minimal userspace inclusion)
	sys/netipsec/ipsec_netbsd.c	(redo sysctl subtree from scratch)
	sys/netipsec/key*.c		(fix broken net.key subtree)

	sys/netipsec/ah_var.h		(increase all counters to 64 bits)
	sys/netipsec/esp_var.h		(increase all counters to 64 bits)
	sys/netipsec/ipip_var.h		(increase all counters to 64 bits)
	sys/netipsec/ipcomp_var.h	(increase all counters to 64 bits)

	sys/netipsec/ipsec.c		(add #include netipsec/ipsec_var.h)
	sys/netipsec/ipsec_mbuf.c	(add #include netipsec/ipsec_var.h)
	sys/netipsec/ipsec_output.c	(add #include netipsec/ipsec_var.h)

	sys/netinet/raw_ip.c		(add #include netipsec/ipsec_var.h)
	sys/netinet/tcp_input.c		(add #include netipsec/ipsec_var.h)
	sys/netinet/udp_usrreq.c	(add #include netipsec/ipsec_var.h)

Changes to usr.bin/netstat to print the new fast-ipsec sysctl tree
for "netstat -s -p ipsec":

New file:
	usr.bin/netstat/fast_ipsec.c	(print fast-ipsec counters)

Changed files:
	usr.bin/netstat/Makefile	(add fast_ipsec.c)
	usr.bin/netstat/netstat.h	(declarations for fast_ipsec.c)
	usr.bin/netstat/main.c		(call KAME-vs-fast-ipsec dispatcher)

65e5548a17 Add MBUFTRACE kernel option. 
Do a little mbuf rework while here.  Change all uses of MGET*(*, M_WAIT, *)
to m_get*(M_WAIT, *).  These are not performance critical and making them
call m_get saves considerable space.  Add m_clget analogue of MCLGET and
make corresponding change for M_WAIT uses.
Modify netinet, gem, fxp, tulip, nfs to support MBUFTRACE.
Begin to change netstat to use sysctl.
