Removed prior audit proof logic - audit proof support was implemented using the generic TLS extension API
Tests exercising the new supplemental data registration and callback api can be found in ssltest.c.
Implemented changes to s_server and s_client to exercise supplemental data callbacks via the -auth argument, as well as additional flags to exercise supplemental data being sent only during renegotiation.
Changes between 1.0.x and 1.1.0 [xx XXX xxxx]
+ *) Add callbacks supporting generation and retrieval of supplemental
+ data entries.
+ [Scott Deboy <sdeboy@apache.org>, Trevor Perrin and Ben Laurie]
+
*) Add EVP support for key wrapping algorithms, to avoid problems with
existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in
the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap
