The last big commit: let usr.sbin/ use WARNS=6 by default.

WARNS=6 cleanup. This includes:
- Apply __unused on unused parameters
- Use const where suitable
- Use PRIu64 instead of the deprecated %q
- Bump WARNS to 6

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

Add and activate the man page for memcontrol(8).
