commit b5c8f42c9b9fce5d1b14866306e7a11e16275942
Author: Matt Caswell <matt at openssl.org>

Remove a hack from ssl_test_old
ssl_test_old was reaching inside the SSL structure and changing the internal
BIO values. This is completely unneccessary, and was causing an abort in the
test when enabling TLSv1.3.
I also removed the need for ssl_test_old to include ssl_locl.h. This
required the addition of some missing accessors for SSL_COMP name and id
fields.
