Continuing analysis of Thief videos in a working Wine build (current git +
28d6203ca9bd0ba17ce38e309f340b518f954c08 reverted and zero byte samples patch
NOT applied). I'm looking further into differences that "fix handling of zero
byte samples" patch introduces. I've added debug output in
AVISplitter_next_request, that is supposed to call AVISplitter_SendEndOfFile,
and it shows that 

1) thief avis only seem to enter the "else if (This->oldindex) { } " path
2) stream->index always seems to be 0

Furthermore, I don't see any obvious way how stream->index can become anything
but 0 for such a video.

This may explain why end of file is never detected in Thief videos with "fix
handling of zero byte samples" as it replaces the end of file detecting
conditional

-            if (stream->pos_next * sizeof(This->oldindex->aIndex[0]) >=
This->oldindex->cb)
+            if (stream->index)

to one that will never be true.
