[PATCH 2/5] Move max_threads variable declaration into include file

[Andi Kleen <andi@firstfloor.org>]

From: Andi Kleen <ak@linux.intel.com>

Multiple files have a private extern for the max_threads variable
defined in fork.c. Declare it in linux/sched.h and remove the
special externs.

Needed for followon patch.
