    rpc: change client insecure port ceiling from 65535 to 49151

    current port allocation to various processes (clumsy):

     1023 - 1       -> client ports range if bind secure is turned on
    49151 - 1024    -> fall back to this, if in above case ports exhaust
    65535 - 1024    -> client port range if bind insecure is on
    49152 - 65535   -> brick port range

    now, we have segregated port ranges 0 - 65535 to below 3 ranges

     1023 - 1       -> client ports range if bind secure is turned on
    49151 - 1024    -> client port range if bind insecure is on
                       (fall back to this, if in above case ports exhaust)
    49152 - 65535   -> brick port range

    so now we have a clean segregation of port mapping
