[PATCH 2/4] ole32: In the data cache, fmtetc->cfFormat and fmtetc->tymed can be 0 which means to match any clipformat/tymed.

[Robert Shearman]

Therefore, keep the clipformat of the data in the data_cf field.

Return an error from SetData if a non-zero clipformat hasn't been specified.

Write out stgmedium.tymed instead of fmtetc.tymed, which is guaranteed 
to be non-zero if data has been set.
