Make generation numbers unsigned and fill them using a random number
from the range [1..UINT_MAX] initially. On inode re-use increment
and on wrap refill from the range [1..UINT_MAX-1] to avoid
assigning UINT_MAX (the original value). Zero still means uninitialized.

UFS does't do inode numbers >2^32, so use a smaller type internally,
only using ino_t in the VFS layer APIs: vget, readdir, getattr.

ufs1_daddr_t is no more, okay deraadt@

ufs_daddr_t is a dead type. growfs is the only program that uses it, yet
it is ffs1-aware only. therefore all the types are on disk, and thus,
they are actually int32_t. ok pedro

some pieces of ufs2. help testing otto sturm

rename struct dinode to ufs1_dinode. clears the namespace and makes
way for some future work. no function changes yet.
few other little cleanups.

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

fiddle with some type names. change most instances of ufs_daddr_t to
ufs1_daddr_t, a few to daddr_t. ufs_daddr_t typedef is retained, but consider
it deprecated. no functional changes. inspired by freebsd. ok art@

branches: 1.5.2;
Opps. Back out a part of last commit that wasn't intended for commit yet.

Use u_int32_t for lfs inode number.
If we would ever change ino_t, the struct dinode would break.
