Bahadir Balban 18ffa0b4d1 Added a TASK_CAP_LIST macro that abstracts away the primary cap list
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.
