lib: set version 1.2.3r2 and more helper macros

Browse Source 
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.
