Log:
  sfxge(4): add function to create packed stream RxQ
  
  Encoding packed stream buffer size in RxQ type is not a future-proof
  idea taking into account a new RxQ types with extra parameters.
  To be consistent make packet stream buffer size a separate parameter.
  In order to avoid blowing of the default RxQ create function prototype
  add a dedicated function to create packed stream RxQ without not
  applicable paramters.
