in particular a single write will result in a single re-key event,
rather than 64 writes causing 64 re-keys -- wasting the kernel's time.

As schwarze@ also stated, this will prevent anyone from calling it
(which would be an error) and makes it clearer that rc.subr is not just
a functions container.
No functionnal change, unless you were calling rc_conf from an rc script
which would have been wrong anyway.

rc.conf.

local_rcconf would get overwritten by flags from the rc script itself.
Based on an original idea and diff from robert@, create an rc_conf
function that we add in the rc_script after the defaults daemon*
variables.
This way we can use defaults variables names in other part of the script
(when defining a specific pexp for instance).
While here, simplify setting up the default daemon variables so that we
don't need to do any substitution in rc_start.
rc scripts must include daemon variables before calling rc_conf. All
other locally modified variables (pexp, rc_reload, local additions...)
must come after.
