[CI] Clusterwide pids are here (optionally, if you want them)

[<br...@ka...>]

There is a new release of Cluster Infrastructure.   Besides moving
up to 2.4.6 kernel and including
the patches to allow it run on Alpha, it has support for
clusterwide pids (we brought it over from the SSI project
since there seemed to be interest).  In doing the configuration
of the kernel, the CPID capability is optional.

So far the configuration capability is pretty simple.  If you have
a hankering to tinker, feel free.
