This is a redesign of the root and parent interfaces to eliminate blocking RPC calls. - New session representation at the parent (base/session_state.h) - base-internal root proxy mechanism as migration path - Redesign of base/service.h - Removes ancient 'Connection::KEEP_OPEN' feature - Interface change of 'Child', 'Child_policy', 'Slave', 'Slave_policy' - New 'Slave::Connection' - Changed child-construction procedure to be compatible with the non-blocking parent interface and to be easier to use - The child's initial LOG session, its binary ROM session, and the linker ROM session have become part of the child's envirenment. - Session upgrading must now be performed via 'env.upgrade' instead of performing a sole RPC call the parent. To make RAM upgrades easier, the 'Connection' provides a new 'upgrade_ram' method. Issue #2120
