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.

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

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.

This also eliminates code duplication between x86_64-mont and x86_64-mont
and optimizes even original non-MULX code.
