This one changes textconv_object() to take a pointer to ulong*; a caller
is changed to cast a long* down to that pointer (in fill_origin_blob);
that is shifting one type-punned pointer problem to another one, so I do
not think it is an improvement.

... and this depends on that.

The solution should be along the lines of what Jeff outlined in 

    Message-ID: [ref]

i.e.

    The only portable way in C to convert between types is by assignment. So
    you have to do:

      unsigned long foo;
      textconv_object(read_from, null_sha1, &buf.buf, &foo);
      buf.len = foo;
