Stephen Hemminger cb056611a8 eal: rename lcore master and slave 
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.
