DPDK has a two features in dpdk 16.04.
1) reduce start up time
2) signal handler when will be killed and do some clean up
This patch is to enable automation for the features.

+
+======================================
+DPDK enable short-lived application
+======================================
+This feature is to reduce application start up time, and when exit, do more
+clean up so that it could be re-run many times.
+
+Prerequisites
+-------------
+To test this feature, need to using linux time
+and start testpmd by:
+create and mount hugepage, must create more hugepages so that could measure time more obviously.
+ # echo 8192 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
+ # mount -t hugetlbfs hugetlbfs /mnt/huge
+Bind nic to DPDK
+ ./tools/dpdk_nic_bind.py -b igb_uio xxxx:xx:xx.x
+start testpmd using time
+ # echo quit | time ./testpmd -c 0x3 -n 4 -- -i
+
+-------------------------------------------------------------------------------
+Test Case 1: basic fwd testing
+-------------------------------------------------------------------------------
+1. start testpmd
+ ./testpmd -c 0x3 -n 4 -- -i
+2. set fwd mac
+3. send packet from pkg
+4. check all packets could be fwd back
+
+-------------------------------------------------------------------------------
+Test Case 2: Get start up time
+-------------------------------------------------------------------------------
+1. start testpmd
+ echo quit | time ./testpmd -c 0x3 -n 4 --huge-dir /mnt/huge -- -i
+2. get the time stats of the startup
+3. repeat step 1~2 for at least 5 times to get the average
+
+-------------------------------------------------------------------------------
+Test Case 3: Clean up with Signal -- testpmd
+-------------------------------------------------------------------------------
+1. create 4G hugepages, so that could save times when repeat
+ echo 2048 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
+ mount -t hugetlbfs hugetlbfs /mnt/huge1
+1. start testpmd
+ ./testpmd -c 0x3 -n 4 --huge-dir /mnt/huge1 -- -i
+2. set fwd mac
+3. send packets from pkg
+4. check all packets could be fwd back
+5. kill the testpmd in shell using below commands alternately:
+ SIGINT: pkill -2 testpmd
+ SIGTERM: pkill -15 testpmd
+6. repeat step 1~5 for 20 times, and packet must be fwd back with no error for each time.
+
+-------------------------------------------------------------------------------
+Test Case 4: Clean up with Signal -- l2fwd
+-------------------------------------------------------------------------------
+1. create 4G hugepages, so that could save times when repeat
+ echo 2048 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
+ mount -t hugetlbfs hugetlbfs /mnt/huge1
+1. start testpmd
+ ./l2fwd -c 0x3 -n 4 --huge-dir /mnt/huge1 -- -p 0x01
+2. set fwd mac
+3. send packets from pkg
+4. check all packets could be fwd back
+5. kill the testpmd in shell using below commands alternately:
+ SIGINT: pkill -2 l2fwd
+ SIGTERM: pkill -15 l2fwd
+6. repeat step 1~5 for 20 times, and packet must be fwd back with no error for each time.
+
+-------------------------------------------------------------------------------
+Test Case 5: Clean up with Signal -- l3fwd
+-------------------------------------------------------------------------------
+1. create 4G hugepages, so that could save times when repeat
+ echo 2048 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
+ mount -t hugetlbfs hugetlbfs /mnt/huge1
+1. start testpmd
+ ./l3fwd -c 0x3 -n 4 --huge-dir /mnt/huge1 -- -p 0x01 --config="(0,0,1)"
+2. set fwd mac
+3. send packets from pkg
+4. check all packets could be fwd back
+5. kill the testpmd in shell using below commands alternately:
+ SIGINT: pkill -2 l3fwd
+ SIGTERM: pkill -15 l3fwd
+6. repeat step 1~5 for 20 times, and packet must be fwd back with no error for each time.
