       pmlogconf: use the correct dm metrics in the atop set
       qa: update expected 201 output for new pmdacache testing
       pcp-atop: reading from PCP archives now operational


some initial review after pulling in Nathan's master branch.

builds and installs fine on my f19 laptop, and runs fine with no
arguments. Looks like a great tool.


# pcp --archive=/var/log/pcp/pmlogger/fletch/20150603.13.28 atop
dies with a messed up screen and glibc heap issues

# pcp -h somehost atop
pcp-atop: task instances: No permission to perform requested operation
Doesn't work as root either.

I've more comments - but was expecting the above to work ..? Also, the
man page says "pcp-atop -r" will replay todays archive from
/var/log/pcp/pmlogger/<pmcd.hostname>/.... but I get a usage message.

Also, are we intending to still support the native atop raw data format
for recording and playback. Or just switch to PCP archives and/or archive
folios? How much back-compat with upstream will we be maintaining?
