    Make the addition of the d_gone binary compatible.  This allows
    storage drivers compiled for 9.0 to work on 9.1 and preserves the ABI
    for disks.

    MFS after:      releng/9.1 gets sorted

This change fixes the binary compatibility problems with additions to
the disk(9) API.  Disk drivers compiled against 9.0 will not work on
9.1-RC1, but should start working after this change or in 9.1-RC2 and
later.  Disk drivers should not be linked against 9.1-RC1 for
distribution, except specifically for testing on RC1.  This was
planned for RC1, but it was delayed due to circumstancs beyond my
control.
