service: fixup shared_from_this saga for setOwner/setParent.

We now catch the bad weak ptr and create the shared_ptr
ourselves. This is allowed since we know that it is stored
in the other Service and not destructed at the end of the
function.

In addition, for Boost 1.53+. use enable_shared_from_raw which
has the old enable_shared_from_this2 behavior again.
