Actually define the task_pid() and task_tgid() functions. Also
replace pid with __pid so as to make sure any missed accessors are
caught.
The resulting object code seems to be identical in most cases, and is
actually shorter in cases where current->pid is used twice in a row,
as it does not dereference task-> twice.
