Document i2d_PublicKey better.
The name is confusing. EC keys aren't serialized to DER.
DSA keys are also weird, but left alone for now. i2d_DSAPublicKey either
serializes to a DSAPublicKey per RFC 3279 if write_params is 0 or what
seems to be an OpenSSL-specific format that includes the group if
write_params is 1. See upstream's
ea6b07b54c1f8fc2275a121cdda071e2df7bd6c1.
