Note that it initially applies to 1.0.2, and not to HEAD. This is
in order to allow development with existing libunbound installations
that are dependent on OpenSSL 1.0.x. More details in RT.

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.

Add CMS_RecipientInfo_encrypt: this function encrypts an existing content
encryption key to match the key in the RecipientInfo structure: this is
useful if a new recpient is added to and existing enveloped data structure.

Add documentation.
