dnl EFL_VERSION(major, minor, micro, release)
dnl This setup EFL version information and should be called BEFORE AC_INIT().
dnl
dnl release parameter is 'dev' to use from SVN or libtool -release field.
dnl It may be empty if not dev (svn/live build) and no -release is to be used.
dnl
dnl Examples:
dnl     EFL_VERSION(1, 7, 99, dev)
dnl     EFL_VERSION(1, 7, 99, ver-1234)
dnl This will define couple of m4 symbols:
dnl     v_maj = given major number (first parameter)
dnl     v_min = given minor number (second parameter)
dnl     v_mic = given micro number (third parameter)
dnl     v_rev = if release, it's 0, otherwise it's dev_version.
dnl     v_rel = if release, it's -release followed by fourth parameter,
dnl             otherwise it's empty. (mostly for libtool)
dnl     efl_version = if release, it's major.minor.micro, otherwise it's
dnl             major.minor.micro.dev_version
dnl     dev_version = development version (svn revision).
dnl     def_build_profile = dev or release based on 'dev' release parameter.
