[PATCH] Remove CTL_UNNUMBERED

From: Alexey Dobriyan
Date: Thu Jul 26 2007 - 12:45:45 EST

CTL_UNNUMBERED is unneeded, because it expands to

.ctl_name = 0

The same effect can be achieved by skipping .ctl_name initialization,
saving one line per sysctl.

Update docs and headers telling people to not add CTL_ numbers and
giving example.

This is probably all we can do to stop the flow of new CTL_ numbers,
because most of sysctls are copy-pasted. CTL_UNNUMBERED doesn't solve
this problem at all.

into the kernel and then as a separate patch allocate a binary sysctl number.
