Fix a limitation in SSL_CTX_use_certificate_chain_file(): use algorithm
specific chains instead of the shared chain.

Update docs.

For DTLS we might need to retransmit messages from the previous session
so keep a copy of write context in DTLS retransmission buffers instead
of replacing it after sending CCS. CVE-2013-6450.
(cherry picked from commit 34628967f1e65dc8f34e000f0f5518e21afbfc7b)

Fix padding calculation for different SSL_METHOD types. Use the
standard name as used in draft-agl-tls-padding-02

Based on a suggested workaround for the "TLS hang bug" (see FAQ and PR#2771):
if the TLS Client Hello record length value would otherwise be > 255 and less
that 512 pad with a dummy extension containing zeroes so it is at least 512.

To enable it use an unused extension number (for example 0x4242) using
e.g. -DTLSEXT_TYPE_wtf=0x4242

WARNING: EXPERIMENTAL, SUBJECT TO CHANGE.

Add various functions to allocate and set the fields of an ECDSA_METHOD
structure.

(This went into 1.0.2 too, so it's not actually a change
between 1.0.x and 1.1.0.)

the main branch (http://cvs.openssl.org/chngview?cn=19322) later added
to the 1.0.2 branch (http://cvs.openssl.org/chngview?cn=23113), and
thus not a change "between 1.0.2 and 1.1.0".

(Various changes from the master branch are now in the 1.0.2 branch too.)

Experimental support for encrypt then mac from
draft-gutmann-tls-encrypt-then-mac-02.txt

To enable it set the appropriate extension number (0x10 for the test server)
using e.g. -DTLSEXT_TYPE_encrypt_then_mac=0x10

For non-compliant peers (i.e. just about everything) this should have no
effect.

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.

Add support for key wrap algorithms via EVP interface.

Generalise AES wrap algorithm and add to modes, making existing
AES wrap algorithm a special case.

Move test code to evptests.txt

Extend OAEP support. Generalise the OAEP padding functions to support
arbitrary digests. Extend EVP_PKEY RSA method to handle the new OAEP
padding functions and add ctrls to set the additional parameters.

Contributed by Trevor Perrin.

Add new methods DTLS_*_method() which support both DTLS 1.0 and DTLS 1.2 and
pick the highest version the peer supports during negotiation.

As with SSL/TLS options can change this behaviour specifically
SSL_OP_NO_DTLSv1 and SSL_OP_NO_DTLSv1_2.

Just a sample, real world applications would have to be cleverer.

Add new verify options to set checks.

Remove previous -check* commands from s_client and s_server.
