[NEW PORT] sysutils/sysctlbyname-improved-kmod: sysctl node to implement an improved sysctlbyname(3) clone

Browse Source 
Kernel module to add the sysctl.entryidinputbyname sysctl node
to allow to implement an improved sysctlbyname(3) clone to handle:

 * a node without a level name, e.g., "security.jail.param.allow.mount."
 * a CTLTYPE_NODE with a no-NULL handler, e.g., "kern.proc.pid.<pid>"

The sysctlbyname_improved() function and an example are provided, too.
