encode_type() initializes alignment, datatype1 and size in all cases, so these
are unnecessary.  The question then becomes where is the best place to
initialize datatype2 (a.k.a. decoded_size).  Since no caller to encode_type()
relies on the existing value being preserved, it makes sense to initialize
it in encode_type().  So just send the patch you originally sent to wine-devel.

Huw.
