Georgios Katsikas 63531389d5 app/testpmd: move variables definition in source 
This patch moves the definition of 3 variables in testpmd.h
into the respective .c file. The idea behind this move is
to allow external applications to compile against testpmd
without throwing compilation errors related to multiple
definition of variables.

Also, an extern dcb_q_mapping in testpmd.h is removed
since it appears that this variable is not defined
elsewhere in the tree.
