    util/ifdtool: add option to change flash layout
    
    The new option "--newlayout <file>" will read <file> in
flashrom's
    layout format and copy flash regions from the current flash image
    file to a new flash image file.
    
    If a region grows, the padding is added at the beginning of the target
    region in the new file so that the data is "right-aligned" to the
    end of the region.
    
    If a region shrinks, a warning is given and the tail end of existing
    data is copied to the target region in the new file.
    
    Regions of zero or negative size are ignored. (In the example below
    00fff000:00000fff regions are an artifact of the address encoding
    in the register fields.)
    
    Example Usage:
    
    Given a flash image for a board with a Sandy Bridge processor and
    Intel 6-Series chipset in the file vpx7654.bin
    
    ifdtool --layout layout.txt vpx7564.bin
    will yield the file layout.txt:
    	00000000:00000fff fd
    	00180000:003fffff bios
    	00001000:0017ffff me
    	00fff000:00000fff gbe
    	00fff000:00000fff pd
    
    Notice that the "bios" portion extends to the end of the 4MB flash.
    It may be edited to extend the bios portion to consume to the extent
    of an 8MB flash. like layout2.txt:
    	00000000:00000fff fd
    	00180000:007fffff bios
    	00001000:0017ffff me
    	00fff000:00000fff gbe
    	00fff000:00000fff pd
    
    ifdtool --newlayout layout.txt vpx7654.bin
    will create a file vpx7654.bin.new that is 8MB.
