[PATCH] Postinstall script ordering in setup


This patch adds a dependence tracking mechanism to postinstall scripts.
The idea is essentially the one described in
<>.  This patch is
very preliminary, and not tested much beyond its ability to sort scripts
correctly (compiles, though).  This should provide a foundation for
further refinement, however.  Please comment.

	* (RunFindVisitor::executeAll): New
	member function that propagates script dependences,
	topologically sorts the script list, and then executes
	the scripts.
	(RunFindVisitor::visitFile): Add file to list instead of
	running it.
	(RunFindVisitor::files): New member variable.
	(processFile): New static helper function that extracts
	dependences from each script file.
	(do_postinstall): Add executeAll call.
	(FileDesc): New helper class.
	(sharpbang): New static helper function.
