selftests: forwarding: mirror_gre_lib: Extract generic functions For non-GRE mirroring tests, a functions along the lines of do_test_span_gre_dir_ips() and test_span_gre_dir_ips() are necessary, but such that they don't assume tunnels are involved. Extract the code from mirror_gre_lib.sh to mirror_lib.sh and convert to just use a given device without assuming it's named "h3-$tundev". Convert the two above-mentioned functions to wrappers that pass along the correct device name. Add test_span_dir() and fail_test_span_dir() to round up the API for use by following patches.
