iopadmap: Refactor and fix tristate buffer mapping. ( #1527 )
...
The previous code for rerouting wires when inserting tristate buffers
was overcomplicated and didn't handle all cases correctly (in
particular, only cell connections were rewired — internal connections
were not).

Fix _TECHMAP_REMOVEINIT_ handling.

Previously, this wire was handled in the code that populated the "do or

only for the first use of a given template.
