Remove exception spec from idl-generated c++ headers.

The general agreement in the project is that c++ exception
specs are pointless and add bloat in production code.

See also this rant for more background:
  http://drdobbs.com/cpp/184401544

This removes the code that generates the exception specs on the
generated c++ headers, and fixes up the few places that broke
subsequently because of widening exception specs, which in turn
was due to the rather unfortunate decision to not have a virtual
dtor in XInterface.
