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
