move in definition of MINFREE from newfs so it can be used by tunefs(8)

delete dead code

merge ffs_root and lfs_root into ufs_root

iget() is gone, VFS_VGET is loading the vnode

iget is gone, getnewvnode() does initialization, mostly

including cluster map info in CGSIZE is dependent on fs->fs_contigsumsize

conditionally avoid synchronous writes (and indicate real fix)

If the offset within the indirect block of the "end block" of our
current cluster is greater than the length of the cluster, then we know
that the start block of the cluster must also be in that indi

If the offset within the indirect block of the "end block" of our
current cluster is greater than the length of the cluster, then we know
that the start block of the cluster must also be in that indirect block
(since the cluster is contiguous) hence the entire cluster is mapped by
a single indirect block (or completely in the direct blocks if end_lvl == 0).
