aesni-x86.pl].

as issuer and subject names. Although this is an incompatible change
it should have little impact in pratice because self-issued certificates
that are not self-signed are rarely encountered.

When a chain is complete and ends in a trusted root checks are also
performed on the TA and the callback notified with ok==1. For
consistency do the same for chains where the TA is not self signed.

avoid entries for deleted functions.

Reverting 1.0.2-only changes supporting the prior authz RFC5878-based tests from commit 835d104f

The contract for custom extension callbacks has changed - all custom extension callbacks are triggered

Whitespace fixes

(cherry picked from commit e9add063)
Conflicts:
	ssl/s3_clnt.c

If multiple TLS extensions are expected but not received, the TLS extension and supplemental data 'generate' callbacks are the only chance for the receive-side to trigger a specific TLS alert during the handshake.

Removed logic which no-op'd TLS extension generate callbacks (as the generate callbacks need to always be called in order to trigger alerts), and updated the serverinfo-specific custom TLS extension callbacks to track which custom TLS extensions were received by the client, where no-ops for 'generate' callbacks are appropriate.

Free generated supp data after handshake completion, add comment regarding use of num_renegotiations in TLS and supp data generation callbacks

Conflicts:
	apps/s_client.c

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.

If an application calls the macro SSL_CTX_get_extra_chain_certs
return either the old "shared" extra certificates or those associated
with the current certificate.

This means applications which call SSL_CTX_use_certificate_chain_file
and retrieve the additional chain using SSL_CTX_get_extra_chain_certs
will still work. An application which only wants to check the shared
extra certificates can call the new macro
SSL_CTX_get_extra_chain_certs_only
