Features for RRDtool 1.3

Certain

1. Switch form libart to cairo for graph output (tobi)
2. Use posix_fadvise to drop cache where it is not needed. This should give us a beautiful performance boost in update time.
3. Investigate and document file system performance tuning for rrdtool. (tobi)
4. rrdtool accelerator inspired by Philippe Simonet (tobi)
5. Architecture independent data format with xdr (tobi with help from Matt Massie)
6. commandline parsing with popt (or some other thread-safe thing) (tobi)

Maybe

• C-friendlier API
• SQL interface ​http://lists.ee.ethz.ch/p/02-rrdtool+libdbi.patch (Martin Sperl ?) ...
