    Use calloc to allocate xports (BZ #17542)
    
    If xports is NULL in xprt_register we malloc it but if sock >
    _rpc_dtablesize() that memory does not get initialised and may in theory
    contain any value. Later we make a conditional jump in svc_getreq_common
    based on the uninitialised memory and this caused a general protection
    fault in rpc.statd on an older version of glibc but this code has not
    changed since that version.
    
    Following is the valgrind warning.
