sysctl.7. Remove the list of MIBs from sysctl.8 so we don't have to maintain duplicate information, as proposed by YAMAMOTO Takashi on tech-userlevel. Also remove references to header files from sysctl.8. The numeric constants remain documented, they are still needed in some cases. See the discussion on tech-userlevel. ("mib list in sysctl.8") OK by YAMAMOTO Takashi.
