sched: automated per session task groups

A recurring complaint from CFS users is that parallel kbuild has a negative
impact on desktop interactivity.  This patch implements an idea from Linus,
to automatically create task groups.  This patch only implements Linus' per
tty task group suggestion, and only for fair class tasks, but leaves the way
open for enhancement.

Implementation: each task's signal struct contains an inherited pointer to a
refcounted autogroup struct containing a task group pointer, the default for
all tasks pointing to the init_task_group.  When a task calls __proc_set_tty(),
the process wide reference to the default group is dropped, a new task group is
created, and the process is moved into the new task group.  Children thereafter
inherit this task group, and increase it's refcount.  On exit, a reference to the
current task group is dropped when the last reference to each signal struct is
dropped.  The task group is destroyed when the last signal struct referencing
it is freed.   At runqueue selection time, IFF a task has no cgroup assignment,
it's current autogroup is used.

The feature is enabled from boot by default if CONFIG_SCHED_AUTOGROUP is
selected, but can be disabled via the boot option noautogroup, and can be
also be turned on/off on the fly via..
   echo [01] > /proc/sys/kernel/sched_autogroup_enabled.
..which will automatically move tasks to/from the root task group.

Some numbers.

A 100% hog overhead measurement proggy pinned to the same CPU as a make -j10

About measurement proggy:
  pert/sec = perturbations/sec
  min/max/avg = scheduler service latencies in usecs
  sum/s = time accrued by the competition per sample period (1 sec here)
  overhead = %CPU received by the competition per sample period

Average service latency is an order of magnitude better with autogroup.
(Imagine that pert were Xorg or whatnot instead)

Using Mathieu Desnoyers' wakeup-latency testcase:

With taskset -c 3 make -j 10 running..

taskset -c 3 ./wakeup-latency& sleep 30;killall wakeup-latency

without:
maximum latency: 42963.2 µs
average latency: 9077.0 µs
missed timer events: 0

with:
maximum latency: 4160.7 µs
average latency: 149.4 µs
missed timer events: 0
