[PATCH] RPC: introduce client-side transport switch
Move the bulk of client-side socket-specific code into a separate source
file, net/sunrpc/xprtsock.c.
Test-plan:
Millions of fsx operations. Performance characterization such as "sio" or
"iozone". Destructive testing (unplugging the network temporarily, server
reboots). Connectathon with v2, v3, and v4.
