Commit b0b0c0a26e "nfsd: add proc file listing kernel's gss_krb5
enctypes" added an nunnecessary dependency of nfsd on the auth_rpcgss
module.
It's a little ad hoc, but since the only piece of information nfsd needs
from rpcsec_gss_krb5 is a single static string, one solution is just to
share it with an include file.

SUNRPC: Deal with the lack of a SYN_SENT sk->sk_state_change callback...
TI-RPC introduces the capability of performing RPC over AF_LOCAL
sockets. It uses this mainly for registering and unregistering
local RPC services securely with the local rpcbind, but we could
also conceivably use it as a generic upcall mechanism.
This patch provides a client-side only implementation for the moment.
We might also consider a server-side implementation to provide
AF_LOCAL access to NLM (for statd downcalls, and such like).
Autobinding is not supported on kernel AF_LOCAL transports at this
time. Kernel ULPs must specify the pathname of the remote endpoint
when an AF_LOCAL transport is created. rpcbind supports registering
services available via AF_LOCAL, so the kernel could handle it with
some adjustment to ->rpcbind and ->set_port. But we don't need this
feature for doing upcalls via well-known named sockets.
This has not been tested with ULPs that move a substantial amount of
data. Thus, I can't attest to how robust the write_space and
congestion management logic is.

As libtirpc does in user space, have our registration API try using an
AF_LOCAL transport first when registering and unregistering.
This means we don't chew up privileged ports, and our registration is
bound to an "owner" (the effective uid of the process on the sending
end of the transport). Only that "owner" may unregister the service.
The kernel could probe rpcbind via an rpcbind query to determine
whether rpcbind has an AF_LOCAL service. For simplicity, we use the
same technique that libtirpc uses: simply fail over to network
loopback if creating an AF_LOCAL transport to the well-known rpcbind
service socket fails.
This means we open-code the pathname of the rpcbind socket in the
kernel. For now we have to do that anyway because the kernel's
RPC over AF_LOCAL implementation does not support autobind. That may
be undesirable in the long term.

Clean up: Use a more generic name for xs_encode_tcp_fragment_header();
it's appropriate to use for all stream transport types. We're about
to add new stream transport.
Also, move it to a place where it is more easily shared amongst the
various send_request methods. And finally, replace the "htonl" macro
invocation with its modern equivalent.

The TCP connection state code depends on the state_change() callback
being called when the SYN_SENT state is set. However the networking layer
doesn't actually call us back in that case.

The RDMA CM currently infers the QP type from the port space selected
by the user. In the future (eg with RDMA_PS_IB or XRC), there may not
be a 1-1 correspondence between port space and QP type. For netlink
export of RDMA CM state, we want to export the QP type to userspace,
so it is cleaner to explicitly associate a QP type to an ID.
Modify rdma_create_id() to allow the user to specify the QP type, and
use it to make our selections of datagram versus connected mode.

On occasion, it is useful for the NFS layer to distinguish between
soft timeouts and other EIO errors due to (say) encoding errors,
or authentication errors.
The following patch ensures that the default behaviour of the RPC
layer remains to return EIO on soft timeouts (until we have
audited all the callers).
