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 0294b2be)

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.

For consistency with other cases if we are performing

notify the callback with ok==1.

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