QPID-7306: Memory management error in Link/Bridge
qpid::broker Link and Bridge use Connection::requestIOProcessing() to register
callbacks in the connection thread. They were binding a plain "this" pointer to
the callback, but the classes are managed by boost::shared_ptr so if all the
shared_ptr were released, the callback could happen on a dangling pointer.
This fix uses boost::weak_ptr in the callbacks, so if all shared_ptr instances
are released, we don't use the dead pointer.
Link::destroy cannot be skipped, so use a shared_ptr for that.
