[PATCH 0/1] MR2697: winhttp: Support WINHTTP_OPTION_PARENT_HANDLE in request_query_option().

[Vova Mshanetskiy (＠vovams)]

This is needed for mod.io integration in game "The Entropy Centre". Without support for this option the game hangs when trying to authenticate.

Please note that i do not know how Wine works, and have very little understanding of what i am doing. I copied and adjusted code from `connect_query_option()` in the same file. The game does work with this patch though.

Thanks for the patch. You can avoid the cast like this:
```
*(HINTERNET *)buffer = request->connect->hdr.handle;
```
Please also remove the cast from connect_query_option().
