[PATCH 03/40] svc: Change the svc_sock in the rqstp structure to a transport

[Tom Tucker <tom@opengridcomputing.com>]

The rqstp structure contains a pointer to the transport for the 
RPC request. This functionaly trivial patch adds an unamed union 
with pointers to both svc_sock and svc_xprt. Ultimately the 
union will be removed and only the rq_xprt field will remain. This 
allows incrementally extracting transport independent interfaces without 
one gigundo patch.
