Martin Storsjö a899f05f2d Don't have SEncParamExt inherit SEncParamBase
Instead just duplicate the common fields. These fields had to
be duplicated for the C interface compatibility anyway - but
this way there is no risk to accidentally introduce an ABI
break since there is no need for the layout of SEncParamBase to
actually match the start of SEncParamExt.
