After some discussion with David Howells at LSF/MM 2023, we arrived
at a plan to use a single sock_sendmsg() call for transmitting an
RPC message on socket-based transports. This is an initial part of
the transition to support handling folios with file content, but it
has scalability benefits as well.
Comments, suggestions, and test results are welcome.

SUNRPC: Convert svc_tcp_sendmsg to use bio_vecs directly
SUNRPC: Convert svc_udp_sendto() to use the per-socket bio_vec array
SUNRPC: Use a per-transport receive bio_vec array
SUNRPC: Send RPC message on TCP with a single sock_sendmsg() call
