svc: Add xpo_accept transport function
Previously, the accept logic looked into the socket state to determine whether to call accept or recv when data-ready was indicated on an endpoint. Since some transports don't use sockets, this logic now uses a flag bit (SK_LISTENER) to identify listening endpoints. A transport function (xpo_accept) allows each transport to define its own accept processing. A transport's initialization logic is reponsible for setting the SK_LISTENER bit. I didn't see any way to do this in transport independent logic since the passive side of a UDP connection doesn't listen and always recv's. In the svc_recv function, if the SK_LISTENER bit is set, the transport xpo_accept function is called to handle accept processing. Note that all functions are defined even if they don't make sense for a given transport. For example, accept doesn't mean anything for UDP. The function is defined anyway and bug checks if called. The UDP transport should never set the SK_LISTENER bit.
