description:
Rework the various sysctl-related routines to call the correct code
for each version. While here, extract the 5.0 specific code instead
of including in the main rtsock.c code.
Also, clean up all the sysctl-related routines to prevent building
more than one copy, no matter how many places rtsock.c gets #include'd
into!
