Subject: [PATCH v2 0/3] sysctl: move sysctl type to ctl_table_header

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
