This patch makes dkctl(8) command show all the available
infomation about the device (== you don't need to type long
command names).

Result looks like:

        # dkctl wd0
        strategy:
        wd0d: disksort

        cache:
        wd0d: read cache enabled
        wd0d: write-back cache enabled
        wd0d: read cache enable is not changeable
        wd0d: write cache enable is changeable
        wd0d: cache parameters are not savable
