* W32CommonDeviceOpen
*
* This routine is the callback which is ALWAYS called by wave and midi
* functions. This is done to ensure that the XXXXHDR structure keeps
* getting copied back from 32 bit space to 16 bit, as it contains flags
* which the application is liable to keep checking.
*
* The way this whole business works is that the wave/midi data stays in 16
* bit space, but the XXXXHDR is copied to the 32 bit side, with the
* address of the data thunked accordingly so that Robin's device driver
* can still get at the data but we don't have the performance penalty of
* copying it back and forth all the time, not least because it is liable
* to be rather large...
*
* It also handles the tidying up of memory which is reserved to store
* the XXXXHDR, and the instance data (HWND/Callback address; instance
* data; flags) which the xxxxOpen calls pass to this routine, enabling
* it to forward messages or call callback as required.
*
* This routine handles all the messages that get sent from Robin's
* driver, and in fact thunks them back to the correct 16 bit form. In
* theory there should be no MM_ format messages from the 16 bit side, so
* I can zap 'em out of WMSG16. However the 32 bit side should thunk the
* mesages correctly and forward them to the 16 bit side and thence to
* the app.
*
* However... I discover that somewhere in the system the wParam Msg
* parameter (which is 32 bits in Win32 and 16 bits in Win16) is having
* the top 16 bits trashed (zeroed actually). As I pass a 32 bit handle
* in it, to be thunked in WMDISP32 back to a 16 bit handle, the loss of
* the top 16 bits is not conducive to correct thunking. Soooo, no more
* thunking in WMDISP32 - I do it all here and Post the correct 16 bit
* message.
*
* Hence WMTBL32 (the 32 bit message switch table) contains the
* NoThunking entry for all the MM_ messages - I'll do 'em myself thank
* you.
*
*
* For the MM_WIM_DATA and MM_WOM_DONE message dwParam1 points to the
* following data struture.
*
* P32HDR is a 32 bit pointer to the original 16 bit header
* P16HDR is a 16 bit far pointer to the original 16 bit header
*
* If we need to refernece the original header we must do via the
* P32HDR pointer.
*
