Praparation series to enable constification of struct ctl_table further
down the line.
No functional changes are intended.

These changes have been split out and reworked from my original
const sysctl patchset [0].
I'm resubmitting the patchset in smaller chunks for easier review.
Each split-out series is meant to be useful on its own.

Changes since the original series:
* Explicit initializartion of header->type in init_header()
* Some additional cleanups

Took me some time but I finally got around to it. I just had comments
regarding the commit messages. I'll add this to sysctl testing to get
the ball rolling; I'll add it to sysctl-next after you modify the commit
messages.

Thx.

This all looks super sexy to me, but I'd love Eric's feedback on patch
series before merging as he may know some other facts over sysctl_mount_point
I might be missing.
