    tools: add Yafut to enable creating Yaffs filesystem images
    
    The Yafut tool has so far been used to update the kernel on devices with
    NAND flash via MTD character devices.  Recent upstream updates extended
    the tool with limited support for working with filesystem images stored
    in regular files.  This enables Yafut to be used for preparing a Yaffs
    filesystem image for a device with NOR flash on a build host and
    subsequently flashing it to the target device without using Yafut
    itself.
    
    Add Yafut to tools/ so that it can be compiled and run on the host
    building OpenWRT.
