Subject: [PATCH] Mark void pointers as gpointer

Otherwise the ABI is not properly respected as for some reason,
mem::size_of::<c_void>() returns 1 on a 64bits system. In the case
of GstVideoDecoder(Class), the ABI mistmatches because of the
`void * padding[14]` field which is translated to
`pub padding: [c_void; 14]` which size was 14(bytes) instead of
112 (on 64bits systems).
