INT 31 - DPMI 0.9+ - RESIZE DOS MEMORY BLOCK

	AX = 0102h
	BX = new block size in paragraphs
	DX = selector of block
Return: CF clear if successful
	CF set on error
	    AX = DOS error code (07h,08h,09h)
		  (see #01680 at INT 21/AH=59h/BX=0000h)
		(DPMI 1.0+) DPMI error code (8011h,8022h) (see #03143)
	    BX = maximum block size (in paragraphs) possible
Notes:	increasing the size of a block past a 64K boundary will fail if the
	  next descriptor in the LDT is already in use
	shrinking a block past a 64K boundary will cause some selectors to be
	  freed; DPMI 1.0+ automatically zeros any segment registers containing
	  a selector freed by this function
	not supported by MS Windows 3.0 in Standard mode
