Module Name:    src

Modified Files:
        src/sys/ufs/ffs: ffs_alloc.c ffs_extern.h ffs_snapshot.c ffs_softdep.c

Log Message:
Split ffs_freefile into a frontend for normal cylinder group and for
snapshot use. Adjust ffs_blkfree_common to get the fs instance passed
in, the original commit didn't account blocks in the snapshots
correctly. Assert that ffs_blkfree is used with the primary fs instance
and that ffs_checkfreefile is only used for snapshots. Move the bdwrite
from ffs_blkfree_common into the caller for symmetry. This creates a
redundant write of unmodified data for ffs_blkfree_snap if a double free
of a block happens.
