The measure_perf function should be executed after worker threads exit
to collect correct perf data. Otherwise, while workers are running, the
main thread may get incomplete data from workers.
In the meanwhile, remove unnecessary barrier in the test.
For signal variables "ldata.done" and "ldata.start", no operations
should keep the order that being executed after them. So the wmb after
them can be moved.

Replace master lcore with main lcore and
replace slave lcore with worker lcore.
Keep the old functions and macros but mark them as deprecated
for this release.
The "--master-lcore" command line option is also deprecated
and any usage will print a warning and use "--main-lcore"
as replacement.
