T258, T264, T270: Implement two-level cspace layout using L1/L2 CNode objects.

distops functionality is NYI.

This commit also makes the root cnodes explicit for sys_map(), closes T270.

Notable changes:
* LRPC LMP endpoints are regular capabilities in L2 cnode, no longer in root
cnode.
* Capability operations take a capability address for the root cnode relative
to which capability addresses are to be resolved. The root cnode capability
address must be resolvable in the current domains cspace.

Closes T264.

Keep cptrs right-shifted throughout capops.

Fixed some wrongly aligned cptrs in invocations from capops.
