Poul-Henning Kamp 648c711bb4 This is the latest version of the APM stuff from HOSOKAWA, I have looked
briefly over it, and see some serious architectural issues in this stuff.

On the other hand, I doubt that we will have any solution to these issues
before 2.1, so we might as well leave this in.

Most of the stuff is bracketed by #ifdef's so it shouldn't matter too much
in the normal case.
