Due the rest of the state machine changes it makes sense to change the
SSL_state_string return strings from 3* to T*. They are not SSL3 specific

Reusing an SSL object when it has encountered a fatal error can
have bad consequences. This is a bug in application code not libssl
but libssl should be more forgiving and not crash.

Remove RFC5878 code. It is no longer needed for CT and has numerous bugs

Some state strings were erronously not compiled when no-ssl2
was set.

PR#3295

Add callbacks supporting generation and retrieval of supplemental data entries, facilitating RFC 5878 (TLS auth extensions)
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.

Make SRP conformant to rfc 5054.

Changes are:

- removal of the addition state after client hello
- removal of all pre-rfc srp alert ids
- sending a fatal alert when there is no srp extension but when the
server wants SRP
- removal of unnecessary code in the client.

This compiles and runs on Linux, and external applications have no
problems with it.  The definite test will be to build this on VMS.

ssl3_get_message, which is more logical (and avoids a bug,
in addition to the one that I introduced yesterday :-)
and makes Microsoft "fast SGC" less special.
MS SGC should still work now without an extra state of its own
(it goes directly to SSL3_ST_SR_CLNT_HELLO_C, which is the usual state
for reading the body of a Client Hello message), however this should
be tested to make sure, and I don't have a MS SGC client.

Add short state string for MS SGC.
