This change normalizes the SSL_CK_DHE_ #defines to use the common term
"DHE", while permitting older code that uses the more uncommon "EDH"
constants to compile properly.

DHE is the standard term used by the RFCs and by other TLS
implementations.  It's useful to have the internal variables use the
standard terminology.

This patch leaves a synonym SSL_kEDH in place, though, so that older
code can still be built against it, since that has been the
traditional API.  SSL_kEDH should probably be deprecated at some
point, though.

other parts of packet tracing emit the standard "DHE" label instead of
"edh".  This change brings the output of ssl_print_client_keyex() and
ssl_print_server_keyex() into accordance with the standard term.

The standard terminology in https://tools.ietf.org/html/rfc5426 is
"DHE".  "openssl ciphers" outputs "DHE" (for the most part).  But
users of the library currently cannot specify "DHE", they must
currently specify "EDH".

This change allows users to specify the common term in cipher suite
strings without breaking backward compatibility.

ECDHE is the standard term used by the RFCs and by other TLS
implementations.  It's useful to have the internal variables use the
standard terminology.

This patch leaves a synonym SSL_kEECDH in place, though, so that older
code can still be built against it, since that has been the
traditional API.  SSL_kEECDH should probably be deprecated at some
point, though.

other parts of packet tracing emit the standard "ECDHE" label instead
of "EECDH".  This change brings the output of ssl_print_client_keyex()
and ssl_print_server_keyex() into accordance with the standard term.

The standard terminology in https://tools.ietf.org/html/rfc4492 is
ECDHE.  "openssl ciphers" outputs ECDHE.  But users of the library
currently cannot specify ECDHE, they must specify EECDH.

This change allows users to specify the common term in cipher suite
strings without breaking backward compatibility.

(and update performance data, and fix typo)

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

Update docs.

optimization.

When sending an invalid version number alert don't change the

If content is detached and not binary mode translate the input to
CRLF format. Before this change the input was verified verbatim
which lead to a discrepancy between sign and verify.

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.

(and ensure stack alignment in the process)

It worked because it was never called.

SHA512_Transform was initially added rather as tribute to tradition
than for practucal reasons. But use was recently found in ssl/s3_cbc.c
and it turned to be problematic on platforms that don't tolerate
misasligned references to memory and lack assembly subroutine.

Partial mitigation of PR#3200
(cherry picked from commit 0294b2be5f4c11e60620c0018674ff0e17b14238)

Move the IP, email and host checking fields from the public
X509_VERIFY_PARAM structure into an opaque X509_VERIFY_PARAM_ID
structure. By doing this the structure can be modified in future
without risk of breaking any applications.
