  To: ferruh.yigit, wenzhuo.lu, beilei.xing, bernard.iremonger; +Cc: dev

This patch adds multi-process support for testpmd.
The test cmd example as follows:
the primary cmd:
./testpmd -w xxx --file-prefix=xx -l 0-1 -n 2 -- -i\
--rxq=16 --txq=16 --num-procs=2 --proc-id=0
the secondary cmd:
./testpmd -w xxx --file-prefix=xx -l 2-3 -n 2 -- -i\
--rxq=16 --txq=16 --num-procs=2 --proc-id=1
