Allow exception handler callbacks more flexibility (#81). r=bryner

Browse Source 
- Provide an optional filter callback that gets triggered before attempting
   to write a dump, to give client code a chance to refuse handling early
   in the process.
 - Allow exceptions that are unhandled by Airbag (due to filter callback or
   dump callback return value, or failure to write a dump) to be passed to the
   previous handler or to the system.
 - In order to pass exceptions unhandled by the topmost Airbag handler to
   lower handlers, fix up the stacking of ExceptionHandler objects, and give
   each ExceptionHandler object its own thread (like the Mac implementation)
   to avoid deadlock.
 - Provide a dump_path argument to callbacks, as requested by developers and
   already implemented in the Mac handler.
 - Avoid calling c_str in exception handler code (#90).
