MFC 253262, 253318, 243184, 253444, 253505, 253520:

- Add a leaf node CTL_NET.PF_ROUTE.0.AF.NET_RT_DUMP.0.FIB. This returns
routing table with the specified FIB number, not td->td_proc->p_fibnum.

- Add check_namevarlist() to check if ${name}_var is reserved in
rc.subr or not.

- Fix a bug in ipv6_prefix_IF. It did not work with the 64-bit prefix
notation like 2001:db8:1:1.

- Use eui64 flag in ifconfig(8) instead of network6_getladdr()[*] for
interface indentifier part.

- Fix address range specification with ifconfig(8) options such as:

* inet 192.0.2.1-10 netmask 255.255.255.0 (inet range spec + ifconfig options)
* inet6 2001:db8:1::1-f prefixlen 60 (inet6 range spec + ifconfig options)

If prefixlen or netmask option is specified with CIDR notation at
the same time, the option is used.

- Do not set ND6_IFF_ACCEPT_RTADV on if_bridge(4) interfaces when
ipv6_enable=yes.

MFC r231505,231520:

Introduce a new NET_RT_IFLISTL API to query the address list. It works
on extended and extensible structs if_msghdrl and ifa_msghdrl. This
will allow us to extend both the msghdrl structs and eventually if_data
in the future without breaking the ABI.

The MFC is just to provide the new API to old stable branches to make
updating and if needed downgrading a lot easier for updates to 10.

Bump __FreeBSD_version to allow ports to more easily detect the new API.

Add proper const keywords to sysctl(3) parameters.

The `name' and `newp' arguments can be marked const, because the buffers
they refer to are never changed. While there, perform some other
cleanups:

- Remove K&R from sysctl.c.
- Implement sysctlbyname() using sysctlnametomib() to prevent
duplication of an undocumented kernel interface.
- Fix some whitespace nits.

It seems the prototypes are now in sync with NetBSD as well.

This commit includes the following core components:

* rc(8) script and glue code for sensorsd(8)
* sysctl(3) doc fixes for CTL_HW tree
* sysctl(3) documentation for hardware sensors
* sysctl(8) documentation for hardware sensors
* support for the sensor structure for sysctl(8)
* rc.conf(5) documentation for starting sensorsd(8)
* sensor_attach(9) et al documentation
* /sys/kern/kern_sensors.c
o sensor_attach(9) API for drivers to register ksensors
o sensor_task_register(9) API for the update task
o sysctl(3) glue code
o hw.sensors shadow tree for sysctl(8) internal magic
* <sys/sensors.h>
* HW_SENSORS definition for <sys/sysctl.h>
* sensors display for systat(1), including documentation
* sensorsd(8) and all applicable documentation

The userland part of the framework is entirely source-code
compatible with OpenBSD 4.1, 4.2 and -current as of today.

All sensor readings can be viewed with `sysctl hw.sensors`,
monitored in semi-realtime with `systat -sensors` and also
logged with `sensorsd`.
