Poul-Henning Kamp 8177437d85 Complete the bio/buf divorce for all code below devfs::strategy 
Exceptions:
        Vinum untouched.  This means that it cannot be compiled.
        Greg Lehey is on the case.

        CCD not converted yet, casts to struct buf (still safe)

        atapi-cd casts to struct buf to examine B_PHYS
