Changes committed to git://oss.sgi.com/markgw/pcp/pcp.git proc_pmda
(note: 'proc_pmda' branch). Still TODO: pmlogrewrite config for

back to the top level in the pmns (see below).

cgroup got moved to proc.cgroup because of limitations of of the way
Rebuild works for the PMNS and make the transition (when no proc PMDA is
installed) _plus_ our PMDA install scripts and PMNS rebuilding there
cannot handle a leaf metric (not a subtree) at the root of the metric
tree added by a PMDA.

yep, I encountered those issues too.

I moved cgroup to proc.cgroup as the path of least resistance,
especially since pmlogrewrite can also accommodate this style of mapping
if anyone cares there for pmlogger archives.

Well I'm happy to leave it there. And as far as I'm concerned,
I don't see any reason not to merge the proc_pmda branch back
into dev now (the sooner the better to avoid conflicts with
other work going on in the Linux PMDA).
