INT 31 P - DPMI 1.0+ - RESIZE LINEAR MEMORY BLOCK
        AX = 0505h
        ESI = memory block handle
        ECX = new size in bytes (nonzero)
        EDX = flags
            bit 0: create committed pages rather than uncommitted pages
            bit 1: segment descriptor update required
                ES:EBX -> buffer containing array of WORDs with selectors
                EDI = number of selectors in array
            bits 2-31: reserved (0)
Return: CF clear if successful
            EBX = new linear base address
            ESI = new memory block handle
        CF set on error
            AX = error code (8001h,8012h-8014h,8016h,8021h,8023h)(see AX=0000h)
Notes:  only supported by 32-bit DPMI hosts, but may be used by 16-bit clients
        the old memory block handle becomes invalid
        if EDX bit 1 set and the block's base address is changed, DPMI updates
          all descriptors for selectors in the update buffer which fall within
          the memory block
