Format files and add license comment

Changes to pass tests/scripts/check_files.py
-Add missing new line at end of each file
-Remove any trailing whitespaces
-Added file shebang comments

Added license info and purpose of file descriptions. The 2 test_translate...
files may not be stay later down the line, but incase they do become
permanent, it is good to add the appropriate comments now.

+# On fail, the translated cipher suite names do not match the correct ones.

+#
