The first part continues fix from PR #539: references to
alogandelogwere fixed (replaced withshared_ptr) but reference torngwas not. Ifrngis accessed afterendpointis destroyed, application crashes.The second part fixes crash in
endpoint::handle_connect()called whenendpointis already destroyed. The fix is to captureshared_ptrinstead of rawthispointer (similar to callbacks inconnection).The crashes occurred regularly in automated tests for application that creates and destroys
endpointfor each client connection.
