    David Howells authored
    Support network namespacing in AF_RXRPC with the following changes:
    
     (1) All the local endpoint, peer and call lists, locks, counters, etc. are
         moved into the per-namespace record.
    
     (2) All the connection tracking is moved into the per-namespace record
         with the exception of the client connection ID tree, which is kept
         global so that connection IDs are kept unique per-machine.
    
     (3) Each namespace gets its own epoch.  This allows each network namespace
         to pretend to be a separate client machine.
    
     (4) The /proc/net/rxrpc_xxx files are now called /proc/net/rxrpc/xxx and
         the contents reflect the namespace.
    
    fs/afs/ should be okay with this patch as it explicitly requires the current
    net namespace to be init_net to permit a mount to proceed at the moment.  It
    will, however, need updating so that cells, IP addresses and DNS records are
    per-namespace also.
