VFS mega cleanup commit (x/N)

1.  Add new file "sys/kern/vfs_default.c" where default actions for
    VOPs go. Implement proper defaults for ABORTOP, BWRITE, LEASE,
    POLL, REVOKE and STRATEGY.  Various stuff spread over the entire
    tree belongs here.

2.  Change VOP_BLKATOFF to a normal function in cd9660.

3.  Kill VOP_BLKATOFF, VOP_TRUNCATE, VOP_VFREE, VOP_VALLOC.  These
    are private interface functions between UFS and the underlying
    storage manager layer (FFS/LFS/MFS/EXT2FS).  The functions now
    live in struct ufsmount instead.

4.  Remove a kludge of VOP_ functions in all filesystems, that did
    nothing but obscure the simplicity and break the expandability.
    If a filesystem doesn't implement VOP_FOO, it shouldn't have an
    entry for it in its vnops table.  The system will try to DTRT
    if it is not implemented.  There are still some cruft left, but
    the bulk of it is done.

5.  Fix another VCALL in vfs_cache.c (thanks Bruce!)
