Subject: Make ISA PnP work.  This successfully enumerates as many ISA devices
 as I can fit into my test machine.

 - Move to using STAILQs rather than ad-hoc singly-linked lists.
 - Use a mostly procedural interface to the PnP information.  This
   improves data-hiding.

Implement a new linker-set technique (currently on i386 only but should work
on Alpha as well).  This is a good candidate for replacing the current
gensetdefs cruft completely.
