2008-02-01svc: Move the authinfo cache to svc_xprt.Tom Tucker
Move the authinfo cache to svc_xprt. This allows both the TCP and RDMA transports to share this logic. A flag bit is used to determine if auth information is to be cached or not. Previously, this code looked at the transport protocol. I've also changed the spin_lock/unlock logic so that a lock is not taken for transports that are not caching auth info.

2008-02-01svc: Make close transport independentTom Tucker
Move sk_list and sk_ready to svc_xprt. This involves close because these lists are walked by svcs when closing all their transports. So I combined the moving of these lists to svc_xprt with making close transport independent. The svc_force_sock_close has been changed to svc_close_all and takes a list as an argument. This removes some svc internals knowledge from the svcs. This code races with module removal and transport addition. Thanks to Simon Holm Thøgersen for a compile fix.

The svc_create_xprt function is a transport independent version of the svc_makesock function. Since transport instance creation contains transport dependent and independent components, add an xpo_create transport function.

2008-02-01svc: Add xpo_accept transport functionTom Tucker
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.

2008-02-01svc: Add an svc transport classTom Tucker
The transport class (svc_xprt_class) represents a type of transport, e.g. udp, tcp, rdma. A transport class has a unique name and a set of transport operations kept in the svc_xprt_ops structure. A transport class can be dynamically registered and unregisterd. The svc_xprt_class represents the module that implements the transport type and keeps reference counts on the module to avoid unloading while there are active users. The endpoint (svc_xprt) is a generic, transport independent endpoint that can be used to send and receive data for an RPC service. It inherits it's operations from the transport class. A transport driver module registers and unregisters itself with svc sunrpc by calling svc_reg_xprt_class, and svc_unreg_xprt_class respectively.
