[PATCH] Postinstall script ordering in setup - take 2

Attached is try #2.  This incorporates Rob's comments from
<>.  I've also
refactored FileDesc to handle all dependence processing.

I think this would be good as a long-term solution as well.  As I
mentioned previously, I don't think we can use the existing package
dependence mechanism unless we also somehow track which package contains
which postinstall scripts.  Personally, I think storing dependences in the
postinstall scripts themselves is cleaner.  Opinions?

	* (RunFindVisitor::executeAll): New
	member function that propagates script dependences,
	topologically sorts the script list, and then executes
	the scripts (via other calls).
	(RunFindVisitor::visitFile): Change to add file to list
	instead of running it immediately.
	(RunFindVisitor::files): New member variable.
	(RunFindVisitor::checkAndLogMissingDependences): New
	member function.
	(FileDesc): New class that extracts and stores
	dependences from a script file.
	(DEPEND_STR): New #define.
	(do_postinstall): Add executeAll() call.
