stobj_unpack_sessinfo should be the reverse of stobj_pack_sessinfo, make
this clearer with respect to the session header and streams processing.

Ok, so we translate p into tmpbuf, then bcopy tmpbuf back to p. That
part makes sense, but I am puzzled by what stobj_pack_sessinfo does:
for (i = 0; i < ses->s_cur_nstreams; i++) {
xlate_invt_stream(strms, (invt_stream_t *)sesbuf, 1);
sesbuf += sizeof(invt_stream_t);
}
Why isn't that callsite xlate_invt_stream(&strms[i], ...); ?
Thanks! Yes, that's wrong, like the existing code it only worked/works
because there's only ever one stream. From the manpage "The third level
is media stream (currently only one stream is supported)". Will fix.
