- split configure options into multiple lines for easy of editing

- add systemtap static markers (wcohen, mjw, dmalcolm; patch 8), a
    systemtap tapset defining "python.function.entry" and
    "python.function.return" to make the markers easy to use (dmalcolm;
    source 5), and an example of using the tapset to the docs (dmalcolm;
    source 6) (rhbz:545179)
