Return an error if an attempt is made to enable the Dual EC DRBG: it
is not used by default.

    - EC_GROUP_cmp shouldn't consider curves equal just because
      the curve name is the same. (They really *should* be the same
      in this case, but there's an EC_GROUP_set_curve_name API,
      which could be misused.)

    - EC_POINT_cmp shouldn't return 0 for ERR_R_SHOULD_NOT_HAVE_BEEN_CALLED
      or EC_R_INCOMPATIBLE_OBJECTS errors because in a cmp API, 0 indicates
      equality (not an error).

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.

If no new reason codes are obtained after checking a CRL exit with an
error to avoid repeatedly checking the same CRL.

This will only happen if verify errors such as invalid CRL scope are
overridden in a callback.

Reencode certificates in X509_sign_ctx as well as X509_sign.

This was causing a problem in the x509 application when it modified an
existing certificate.

While ARMv7 in general is capable of unaligned access, not all instructions
actually are. And trouble is that compiler doesn't seem to differentiate
those capable and incapable of unaligned access. Side effect is that kernel
goes into endless loop retrying same instruction triggering unaligned trap.
Problem was observed in xts128.c and ccm128.c modules. It's possible to
resolve it by using (volatile u32*) casts, but letting STRICT_ALIGNMENT
be feels more appropriate.
