Lots of fixes, notion of pager hierarchy, fixed tgroup capability checking

Browse Source 
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.
