* 29-mar-95 craige initial implementation
* 09-may-95 craige call fn in dll
* 20-jul-95 craige internal reorg to prevent thunking during modeset
* 29-nov-95 angusm added DDHELPREQ_CREATEDSFOCUSTHREAD
* 18-jul-96 andyco added dplayhelp_xxx functions to allow > 1 dplay app to
* host a game on a single machine.
* 3-oct-96 andyco made the winmain crit section "cs" a global so we can take
* it in dphelps receive thread before forwarding requests
* 05-oct-96 colinmc fixed build breaker with CRITICAL SECTION stuff
* 12-oct-96 colinmc new service to load the DirectX VXD into DDHELP
* (necessary for the Win16 lock stuff)
* 18-jan-97 colinmc vxd handling stuff is no longer win16 lock specific
