rq_pid2sbn, rq_pid2esi, rq_pidsetsbn, rq_pidsetesi - get/set SBN,ESI in rq_pid_t

       Bitshifting macros for getting and setting the SBN and ESI bits of rq_pid_t.

       SBN (Source Block Number) is an 8 bit unsigned integer. The Encoding Symbol ID (ESI) is a 24 bit unsigned
       integer in network byte order.

       These macros do not return errors.

       rq_pid2sbn, rq_pid2esi, rq_pidsetsbn, rq_pidsetesi - get/set SBN,ESI in rq_pid_t

rq_pid2sbn()   and   rq_pid2esi()   return  the  uint8_t  SBN  and  uint32_t  ESI  numbers  respectively.
       rq_pidsetsbn() and rq_pidsetesi() both return rq_pid_t with the appropriate bits set.
