Update openafs to release 1.4.0.

The OpenAFS Gatekeepers are pleased to announce the release of version
1.4.0 of OpenAFS. This version incorporates hundreds of enhancements
and improvements since the 1.2 series. Many bugs and programming
inefficiencies (some of which have been present since IBM's donation
of AFS to the open source community) have been eliminated, resulting
in a much more stable product. Improvements for Windows users are
particularly dramatic.

OpenAFS 1.4.0 also represents a significant step forward for Kerberos 5
integration.  This release allows Kerberos 5 KDCs including Microsoft
Active Directory to be the source of AFS client authentication.

Changes under UNIX (tm) and *nix Operating Systems
- --------------------------------------------------
Increased Performance and Stability:

The addition of pthreaded servers and thread optimizations in the
RPC and RX libraries provide increased performance over the 1.2
release.  Cache chunk locking has been refined, and native operating
system vnodes on Linux and MacOS X are now supported. Support for files
larger than two Gigabytes in the AFS file system is now available to
operating systems providing native support for large files.  ntp,
rlogind, rsh and other unnecessary and potentially insecure services
have been removed.

Increased Server Efficiency in Handling Mobile Clients:

Use of multi-host probing has been improved, reducing the time a
server needs to timeout clients no longer accessible on the network.
Server load is reduced by new functionality allowing servers to queue
callback notifications for unreachable clients until the client contacts
the server.

Improved Administration:

Audit logs are available for all servers augmenting existing server
monitoring and debugging tools.  All logs can be output to named pipes
allowing organizations to deploy custom filters.  Groups of groups
(a.k.a. Supergroups) can now be created on the protection server
providing additional flexibility in the administration of user access.
The Kerberos 5 authentication tool, aklog, is now distributed as part
of OpenAFS.

Other New Features:

The new "vos copy" command allows an administrator to create a new
volume and copy the contents of an existing volume in one step.  This
eliminates the need to perform a "vos dump" followed by a "vos restore".

The "vos convertROtoRW" command allows an administrator to convert an
existing RO replica into a new RW site in the event the current RW site
is down.

The -vattachpar file server option reduces file server startup time by
instructing the file server to attach volumes from multiple vice
partitions in parallel.
