nsysctl (new sysctl) is a sysctl(8) utility clone to get or set kernel
state with libxo, sysctlmibinfo and extra options; improvements:
* sysctlmibinfo(3) provides a simple API to the sysctl MIB,
* all code about "opaque values" is in opaque.c,
* output via libxo(3) in human and machine readable formats,
* output is explicitly indicated by the options,
* new option -D show all properties,
* update option -e specific sep as a separator,
* new option -F show flags,
* new option -I show internal nodes,
* new option -l show label,
* new option -r show tag-root with libxo,
* new option -m show format string,
* delete option -n simply do not use -N,
* updated option -N force to show name,
* new option -p show [property-name]: property-value,
* new option -S show magic nodes with -a,
* new option -V if "showable" display value, otherwise hide the state,
* new option -v force to show value,
* new option -y show id.
