Suppress superfluous warnings

- There are many unused parameters. This is ok, so tell gcc to ignore
  them.
- The code still uses the (well-working) class ext::hash_map<>, which
  will trigger deprecation warnings. Ignore this for now; the
  alternatives are only available in recent C++ standard libraries.
- Disable warnings alltogether for Swig-generated code.  Swig
  sometimes generates meaningless self-assignments and triggers strict
  aliasing and a bunch of other warnings. Let's just trust Swig that
  it knows what it is doing.
