Subject: [PATCH 54/59] sysctl: Remove support for directory strategy routines.

From: Eric W. Biederman <ebiederm@...ssion.com> - unquoted

parse_table has support for calling a strategy routine
when descending into a directory.  To date no one has
used this functionality and the /proc/sys interface has
no analog to it.

So no one is using this functionality kill it and make
the binary sysctl code easier to follow.
