pdns pmda changes

["Josef 'Jeff' Sipek" <jeffpc@xxxxxxxxxxxxxx>]

Hello all!

Some time ago, PowerDNS recursor got a perf stats of its own.  I finally
found some time to add those to the pdns pmda.  I pushed the changes to my
repo, but I want to get some review before I push it to pcp/pcp.git.

        git pull git://oss.sgi.com/jeffpc/pcp.git dev

Nathan, I made some changes since you saw the code last night - I
consolidated a couple of metrics into a single metric with a couple of
instances.

Thanks,

Jeff.
