Notion of pager hierarchy introduced using the existing but unused pagerid field. Thread creation now has two more flags TC_AS_PAGER and TC_SHARE_PAGER. The former sets creator as pager, the latter sets creator's pager as pager. Thread group capability sharing now correctly carries shared capabilities to the thread group leader's tgr_cap_list list, and this list is checked during capability checking.
