CT: First step towards supporting Certificate Transparency in Chrome.

This patch adds Signed Certificate Timestamp (SCT) encoding/decoding.
SCT is the Certificate Transparency (CT) structure containing a proof
of a public log's commitment to adding a certificate to its public
repository.

The next patches would be extracting the SCTs when embedded in
certificates and verifying the signature from the SCT over them.
