Tangentially related....

To fix the spice-sdb slotting feature (patches not committed yet, but
awaiting comments), I had to explicitly split gnetlist.scm into two
parts. I moved gnetlist.scm and the netlist backend to load BEFORE
traversing the board, and have  gnetlist-post.scm run AFTER.

This is because I introduced (propose to introduce) a scheme hook for
determining the UREF of a component. This is determined during schematic
traversal time, so at this point, the backend must have loaded.
However.. gnetlist.scm also has some (define ...) code which is
evaluated as soon as gnetlist.scm is loaded, and MUST NOT be run until
after traveral. (This was the bit I moved to gnetlist-post.scm).
