This removes some code because we cannot trace the original contributor
to get their agreement for the licence change (original commit e03ddfae).
After this change there will be numerous failures in the test cases until
someone rewrites the missing code.
All *_free functions should accept a NULL parameter. After this change
the following *_free functions will fail if a NULL parameter is passed:
BIO_ACCEPT_free()
BIO_CONNECT_free()
BN_BLINDING_free()
BN_CTX_free()
BN_MONT_CTX_free()
BN_RECP_CTX_free()
BUF_MEM_free()
COMP_CTX_free()
ERR_STATE_free()
TXT_DB_free()
X509_STORE_free()
ssl3_free()
ssl_cert_free()
SSL_SESSION_free()
SSL_free()
