INT 2F - MS Windows 3.1 - IDENTIFY TSRs

	AX = 160Bh
	ES:DI = 0000h:0000h
Return: ES:DI -> TSR information structure (see #02638)
Desc:	this call allows Windows-aware TSRs to make themselves known to
	  Windows.
Note:	the TSR should first chain to the previous INT 2F handler, then
	  allocate a communication structure, place the returned ES:DI
	  pointer in the first field, and return a pointer to the new
	  structure
