Deprecate find_task_by_pid()

Browse source 
There are some places that are known to operate on tasks'
global pids only:

* the rest_init() call (called on boot)
* the kgdb's getthread
* the create_kthread() (since the kthread is run in init ns)

So use the find_task_by_pid_ns(..., &init_pid_ns) there
and schedule the find_task_by_pid for removal.

What: find_task_by_pid
When: 2.6.26
Why: With pid namespaces, calling this funciton will return the
wrong task when called from inside a namespace.
The best way to save a task pid and find a task by this
pid later, is to find this task's struct pid pointer (or get
it directly from the task) and call pid_task() later.
If someone really needs to get a task by its pid_t, then
he most likely needs the find_task_by_vpid() to get the
task from the same namespace as the current task is in, but
this may be not so in general.
