sched: Add a generic notifier when a task struct is about to be freed
This patch adds a notifier which can be used by subsystems that may be interested in when a task has completely died and is about to have it's last resource freed. The Android lowmemory killer uses this to determine when a task it has killed has finally given up its goods. Signed-off-by: San Mehat <san@google.com>
