INT 31H 0505H: Resize Linear Memory Block

                                                    Compatibility: DPMI 1.0+ 
 Expects: AX    0505H
          ESI   memory block handle (as obtained via INT 31H 0504H)
          ECX   new size of block, in bytes (must not be 0)
          EDX   flags:  bit 0: 1=create committed pages
                               0=create uncommitted pages
                        bit 1: 1=descriptors require update (see Notes)
                               0=do not update descriptors
                         2-31: (reserved; should be 0)
 Returns: CF    NC (clear) if successful; else AX = DPMI Error Code
          EBX   new linear base address of allocated block
          ESI   new handle used to resize and free this block
    Info: Changes the size of a linear memory block allocated via
          INT 31H 0504H.

   Notes: If bit 1 of EDX is set, then you must identify the descriptors
          which need to be updated as follows:  ES:EBX is the address of a
          series of 2-byte selectors whose descriptors need updating and
          EDI is the size of the array, in words.
