Adding support for incremental detailed routing needed for post-routing optimizations such as repairing antenna violations. Other than incremental detailed routing support, this PR includes the following:

  • Reducing the verbosity of the antenna checker.
  • Avoid orderWires effect on the dbNet wires by restoring the wire's state after antenna checking is done.

The antenna checker tests should probably stay verbose, no?

Should I add -verbose to the check_antennas command? That would make the tests extra verbose. The other solution would be making different levels of verbosity.
