limiting mechanics for services
Thanks to the recent change to rc.subr(8) it is no longer necessary to
define a resource limiting logic in service scripts. limits(1) is now run
by default and its configuration is handled via the "${name}_limits"
variable.
Unfortunately, there is a collision of variable names. The service scripts
are broken on FreeBSD version with that new change (>= 12.0).
The patch preserves the old behavior on the systems without the rc.subr(8)
modification.
