Make sunrpc code usable again

  New configure option --enable-obsolete-rpc makes the deprecated RPC
  headers and functions available at compile time as they were before
  version 2.14.  This option will be removed at some time in the future
  after the TI-RPC library becomes fully sufficient for the needs of
  existing applications.
