Add support for attaching aggregation labels to sysctl objects.

I'm currently working on writing a metrics exporter for the Prometheus
monitoring system to provide access to sysctl metrics. Prometheus and
sysctl have some structural differences:

- sysctl is a tree of string component names.
- Prometheus uses a flat namespace for its metrics, but allows you to
attach labels with values to them, so that you can do aggregation.

An initial version of my exporter simply translated

hw.acpi.thermal.tz1.temperature

to

sysctl_hw_acpi_thermal_tz1_temperature_celcius

while we should ideally have

sysctl_hw_acpi_thermal_temperature_celcius{thermal_zone="tz1"}

allowing you to graph all thermal zones on a system in one go.

The change presented in this commit adds support for accomplishing this,
by providing the ability to attach labels to nodes. In the example I
gave above, the label "thermal_zone" would be attached to "tz1". As this
is a feature that will only be used very rarely, I decided to not change
the KPI too aggressively.

Round out SYSCTL macros to the full set of fixed-width types

Add S8, S16, S32, and U32 types; add SYSCTL*() macros for them, as well
as for the existing 64-bit types. (While SYSCTL*QUAD and UQUAD macros
already exist, they do not take the same sort of 'val' parameter that
the other macros do.)

Clean up the documented "types" in the sysctl.9 document. (These are
macros and thus not real types, but the manual page documents intent.)

The sysctl_add_oid(9) arg2 has been bumped from intptr_t to intmax_t to
accommodate 64-bit types on 32-bit pointer architectures.

This is just the kernel support piece; the userspace sysctl(1) support
will follow in a later patch.
