This reduces the preprocessed size of <linux/sched.h> and
speeds up the build a bit.
Also fix code that implicitly relied on headers included by <linux/cgroup-defs.h>.

If we add <linux/uidgid.h> then <linux/sched/user.h> becomes a
self-contained header and users of it either don't need <linux/sched.h>
or have already included it.
This reduces the size of the header dependency graph.

Separate all the MM types that are embedded directly in 'struct task_struct'
into the <linux/mm_types_task.h> header.
The goal is to include this header in <linux/sched.h>, not the full <linux/mm_types.h>
header, to reduce the size, complexity and coupling of <linux/sched.h>.
(This patch does not change <linux/sched.h> yet.)

Most of the structure predeclarations were at the head of sched.h, but not
all of them - there were a number of lines spread around sched.h, in
random places.
Move them to the head, and also sort them alphabetically.

Move rcu_copy_process() into kernel/fork.c, which is the only
user of this inline function.
This simplifies <linux/sched/task.h> to the level that <linux/sched.h>
does not have to be included in it anymore - which change is done
in a subsequent patch.

Linux-0.01 already defined 'current' in the middle of sched.h, so this
is an ancient historical precedent - but still in a modern kernel it
looks a bit weird that we have:
#include <asm/current.h>
in the middle of the header.
Move it further up. If this was done for some obscure dependency
reasons then we'll trigger and document it.
