modify to the way we used XDR definitions files (.x files)

Earlier:
step 1: copy the existing <xdr>.x files to /tmp
step 2: generate '.[ch]' files using 'rpcgen <xdr>.x'
step 3: check diff with the to the existing files, add only your part
        of changes back to the original file. (ignore other changes).
step 4: there is another file to write wrapper functions to convert
        structures to/from XDR buffers, update it with your new structure.
step 5: use these wrapper functions in the newly written procedures.
step 6: commit :-|

Now:
step 1: update (mostly adding only) the <xdr>.x file
step 2: run '<path-to-src>/extras/generate-xdr-files.sh <xdr>.x' command
step 3: implement rpc procedure to handle the request/response.
step 4: commit :-)
