We moved initial list of a pager's caps from ktcb to task's space since the task is expected to trust its space. Most references to task->cap_list had to change. Although a single cap list only tells part of the story about the task's caps, the TASK_CAP_LIST macro works for us to get the first private set of caps that a task has.
