\brief PRF implementation for TLS 1.2, with SHA-256.

This PRF is the one specified by TLS 1.2, when the underlying hash function is SHA-256.

\param dst destination buffer. \param len output length (in bytes). \param secret secret value (key) for this computation. \param secret_len length of "secret" (in bytes). \param label PRF label (zero-terminated ASCII string). \param seed_num number of seed chunks. \param seed seed chnks for this computation (usually non-secret).
