* Many XMPP servers are configured with multiple domains (virtual hosts)
 * In order to establish successfully the TLS connection you have to specify
   which virtual host you are trying to connect.
 * Test this, for example with ::
   * Fail:
       openssl s_client -connect talk.google.com:5222 -starttls xmpp
   * Works:
       openssl s_client -connect talk.google.com:5222 -starttls xmpp -xmpphost gmail.com

 * When the host used in "-connect" is not what the remote XMPP server expects
   the server will return an error like this:
     <stream:error>
       <host-unknown xmlns='urn:ietf:params:xml:ns:xmpp-streams'/>
     </stream:error>
 * But the actual code will stay on the loop forever because the stop condition
   "/stream:features>" will never happen,
 * Make this more robust: The stop condition should be that BIO_read failed
 * Test if for example with ::

    openssl s_client  -connect random.jabb3r.net:5222 -starttls xmpp

 * Some XMPP Servers (OpenFire) use double quotes.
 * This makes s_client starttls work with this servers.
 * Tested with OpenFire servers from http://xmpp.net/ ::

     openssl s_client -connect coderollers.com:5222 -starttls xmpp

OS X 10.8..10.8.3 has broken support for ECDHE-ECDSA ciphers.

(cherry picked from commit 90e7f983b573c3f3c722a02db4491a1b1cd87e8c)

Preliminary documentation for chain and verify stores and certificate chain
setting functions.

This fix ensures that
* A HelloRequest is retransmitted if not responded by a ClientHello
* The HelloRequest "consumes" the sequence number 0. The subsequent
ServerHello uses the sequence number 1.
* The client also expects the sequence number of the ServerHello to
be 1 if a HelloRequest was received earlier.
This patch fixes the RFC violation.

Fix handling of application data received before a handshake.

PR: 3028
Fix bug introduced in PEM_X509_INFO_bio which wouldn't process RSA keys
correctly if they appeared first.

Add X9.42 DH KDF. Move sharedinfo generation code to CMS library as the
same structure is used by DH and ECDH.

Move ASN1_OBJECT typedef to ossl_typ.h so it can be picked up by dh headers
without the need to use ASN1.

Add support for DH parameter generation using DSA methods including
FIPS 186-3.

Make DHparams_dup work properly with X9.42 DH parameters.

Don't need to use temporary buffer if remaining length equals digest length.

Check and set AlgorithmIdenfier parameters for key wrap algorithms.
Currently these just set parameters to NULL.

Bug would emerge when XTS is added to bsaes-armv7.pl. Pointed out by
Ard Biesheuvel of Linaro.

Force no SSL2 when custom extensions in use.
Don't clear extension state when cert is set.
Clear on renegotiate.

This change adds support for ALPN[1] in OpenSSL. ALPN is the IETF
blessed version of NPN and we'll be supporting both ALPN and NPN for
some time yet.

Update ecdsatest to use ECDSA_sign_setup and ECDSA_sign_ex, this
avoids the nonce generation which would otherwise break the test.

Reinstate ecdsatest.

Disable ECDSA test temporarily: it is incompatible with ECDSA nonces.

Add some ECDH CMS tests.
