Gleb Smirnoff cc65eb4e79 Hide struct inpcb, struct tcpcb from the userland. 
This is a painful change, but it is needed.  On the one hand, we avoid
modifying them, and this slows down some ideas, on the other hand we still
eventually modify them and tools like netstat(1) never work on next version of
FreeBSD.  We maintain a ton of spares in them, and we already got some ifdef
hell at the end of tcpcb.

Details:
- Hide struct inpcb, struct tcpcb under _KERNEL || _WANT_FOO.
- Make struct xinpcb, struct xtcpcb pure API structures, not including
  kernel structures inpcb and tcpcb inside.  Export into these structures
  the fields from inpcb and tcpcb that are known to be used, and put there
  a ton of spare space.
- Make kernel and userland utilities compilable after these changes.
- Bump __FreeBSD_version.

This is a mini-SNMP daemon. The basic daemon implements the system group
and a number of private extensions to manage the UDP transport mapping,
communities, trap destinations and loadable modules. In this form it can
be used to provide remote access to arbitrary data that can be described in
the form as required by the SMI. The daemon speaks both SNMPv1 and SNMPv2c.

One basic loadable module is provided together with the daemon:

- snmp_mibII provides the information groups for ip, tcp, and udp.

Installation
------------

As usual by doing:

	configure [--with-libbegemot[=path]]
	make
	make install

This does not install a configuration file. The standard location for the
configuration is /etc/snmpd.config, but can be overwritten on the command
line. An example configuration file is provided. Use --with-libbegemot
to use libbegemot instead of libisc.

Running
-------

	snmpd [-m name[=value]] [-p pid-file] [-c config-file] [-d] [-l prefix]
	      [-D debug-flags] [-I path]

	-m	defines a configuration macro. If no value is given it
		is set to the empty string.

	-p	specify the file where to store the PID. Default is
		/var/run/{prefix}.pid.

	-c	specify the configuration file. Default is /etc/{prefix}.config.

	-d	don't go into daemon mode.

	-l	specify the prefix. This is used for the default config and
		pid file names and for the syslog. Default is "snmpd".

	-D	specify debug flags:

		d	dump all PDUs.

		e	debug event library.

	-I	specify the include path for system configuration files.
		Default is /etc:/usr/etc:/usr/local/etc.

The directory snmpd contains a snmpd.sh script, which can be copied to
/usr/local/etc/rc.d to automatically start and stop the daemon. snmpd.config
is an example config script.
