that needed test_main now works using the same infrastructure as tests that used register_tests. This meant: * renaming register_tests to setup_tests and giving it a success/failure return. * renaming the init_test function to setup_test_framework. * renaming the finish_test function to pulldown_test_framework. * adding a user provided global_init function that runs before the test frame work is initialised. It returns a failure indication that stops the stest. * adding helper functions that permit tests to access their command line args. * spliting the BIO initialisation and finalisation out from the test setup and teardown. * hiding some of the now test internal functions. * fix the comments in testutil.h Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/3953)
