Poul-Henning Kamp 0375c9f2b8 Add a new vnode op, VOP_FREEBLKS(), which filesystems can use to inform
device drivers about sectors no longer in use.

Device-drivers receive the call through d_strategy, if they have
D_CANFREE in d_flags.

This allows flash based devices to erase the sectors and avoid
pointlessly carrying them around in compactions.
