  **The pathset is target for 19.02**

Improved testpmd macswap performance for x86 by take advantage
of SSE instructions.
On a broadwell 1.6GHz sever with a i40e 25G NIC.
We abserve 17.7% performance improvement for testpmd's macswap
test.

  app/testpmd: code refactory for macswap
  app/testpmd: improve MAC swap performance for x86
  app/testpmd: further improve MAC swap performance for x86

v2:

- replace PKT_TX_VLAN_PKT/PKT_TX_QINQ_PKT with PKT_TX_VLAN/PKT_TX_QINQ
- only set vlan / outer_vlan when related ol_flags is set.
- fix coding style
