INT 2F CU - NETWORK REDIRECTOR - FIND FIRST FILE WITHOUT CDSsee Current Directory Structure
	AX = 1119h
	SS = DS = DOS DS
	[DTAsee Disk Transfer Address] = uninitialized 21-byte findfirst search data
	      (see #01626 at INT 21/AH=4Eh)
	SDAsee Swappable Data Area first filename pointer -> fully-qualified search template
	SDAsee Swappable Data Area search attribute = attribute mask for search
Return: CF set on error
	    AX = DOS error code (see #01680 at INT 21/AH=59h/BX=0000h)
	CF clear if successful
	    [DTAsee Disk Transfer Address] = updated findfirst search data
		    (bit 7 of first byte must be set)
	    [DTA+15h] = standard directory entry for file (see #01352)
Notes:	this function is called by the DOS 3.1+ kernel
	DOS 4.x IFSFUNC returns CF set, AX=0003h
