version: add 4th digit and helper macros
Applications can test versions, for compatibility, this way:
#if RTE_VERSION >= RTE_VERSION_NUM(1,2,3,4)
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 is 1.2.3r2.
Releases r0 have not this patch.
