    btrfs: balance filter: add limit of processed chunks · 7d824b6f

    This started as debugging helper, to watch the effects of converting
    between raid levels on multiple devices, but could be useful standalone.
    
    In my case the usage filter was not finegrained enough and led to
    converting too many chunks at once. Another example use is in connection
    with drange+devid or vrange filters that allow to work with a specific
    chunk or even with a chunk on a given device.
    
    The limit filter applies last, the value of 0 means no limiting.
