[dpdk-dev] [PATCH] lib: set version 1.2.3r2 and more helper macros

Applications can test versions, for compatibility, this way:
#if RTE_VERSION >= RTE_VERSION_NUM(1,2,3,4)
Previous versions can be tested with:
#ifndef RTE_VERSION_NUM
RTE_VERSION was already defined for use with rte_config.
It is moved in rte_version.h and updated to current version number.
Note that the first tag having this helper will be 1.2.3r2.
