This patch prefix the mbuf pool ops name with "user" to indicate
that it is user defined.

This patch also change the logic to maintain the value of
user defined and compile time i.e. RTE_MBUF_DEFAULT_MEMPOOL_OPS.

The pktmbuf_create_pool is updated to reflect the same.

The patch itself looks good to me, but I think it deserves to be split
in 2 patches.
