(cherry picked from commit 9250a306)

(cherry picked from commit 4afa9f03)

Backport of patch:
add ECC strings to ciphers(1), point out difference between DH and ECDH

and backport of other other assorted fixes to this man page

 * Make a clear distinction between DH and ECDH key exchange.
 * Group all key exchange cipher suite identifiers, first DH then ECDH
 * add descriptions for all supported *DH* identifiers
 * add ECDSA authentication descriptions
 * add example showing how to disable all suites that offer no
   authentication or encryption
 * update status of static DH (it's now supported)
 * backport descriptions of AES128, AES256, AESGCM
 * backport descriptions of CAMELLIA128, CAMELLIA256
 * backport listing of standard names for ECC cipher suites
   and TLSv1.2 cipher suites
 * backport description of PSK cipher suites

Defines SETUP_TEST_FIXTURE and EXECUTE_TEST, and updates ssl/heartbeat_test.c
using these macros. SETUP_TEST_FIXTURE makes use of the new TEST_CASE_NAME
macro, defined to use __func__ or __FUNCTION__ on platforms that support those
symbols, or to use the file name and line number otherwise. This should fix
several reported build problems related to lack of C99 support.

Remove experimental DANE/dnssec code: not ready for use in an
official release yet.

SRP ciphersuites do not have no authentication. They have authentication
based on SRP. Add new SRP authentication flag and cipher string.

Fix strength_bits to 112 for 3DES.

It's using an internal API that that might not be available in the shared
library.

Because of a missing include <fcntl.h> we don't have O_CREATE and don't create
the file with open() using mode 0600 but fall back to using fopen() with the
default umask followed by a chmod().

Problem found by Jakub Wilk <jwilk@debian.org>.

If application uses tls_session_secret_cb for session resumption
set the CCS_OK flag.

A buffer overrun attack can be triggered by sending invalid DTLS fragments
to an OpenSSL DTLS client or server. This is potentially exploitable to
run arbitrary code on a vulnerable client or server.

Fixed by adding consistency check for DTLS fragments.

Thanks to Jüri Aedla for reporting this issue.

Only accept change cipher spec when it is expected instead of at any
time. This prevents premature setting of session keys before the master
secret is determined which an attacker could use as a MITM attack.

Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for reporting this issue
and providing the initial fix this patch is based on.

Return a fatal error if an attempt is made to use a zero length
master secret.

Unnecessary recursion when receiving a DTLS hello request can be used to
crash a DTLS client. Fixed by handling DTLS hello request without recursion.

Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue.

Add certificates if -nocerts and -certfile specified when signing
in smime application. This can be used this to specify the
order certificates appear in the PKCS#7 structure: some broken
applications require a certain ordering.

Add TLS padding extension to SSL_OP_ALL so it is used with other
"bugs" options and can be turned off.

This replaces SSL_OP_SSLREF2_REUSE_CERT_TYPE_BUG which is an ancient
option referring to SSLv2 and SSLREF.
