[gvg] 12991: Sync to Wine-20050111:

Sync to Wine-20050111:
Robert Shearman [e-mail]
- Remove unnecessary WNDPROC casts.
- Implement RPC_E_DISCONNECTED in proxies.
Mike McCormack [e-mail]
- Use CreateEventW in preference to CreateEventA for unnamed events.
Michael Stefaniuc [e-mail]
- Do not check for non NULL pointer before HeapFree'ing it. It's
  redundant.
Bill Medland [e-mail]
- Implemented DceErrorInqText.
