We used to do several sanity checks when the ebl backend libraries were loaded to make sure there was no version mismatch. When initializing the backend we passed the current Ebl struct size so the library could check it supported the given Ebl struct and we checked that the init method returned the correct build time module version string. Neither are necessary now that the backends are builtin. Remove both the struct size check and the MODVERSION string (which wasn't actually checked anymore). Make the init function return the given Ebl handle or NULL on error (no init function currently indicates any error). Signed-off-by: Mark Wielaard <mark@klomp.org>
