I restructured the ptwrite filtering book-keeping and registration. Now we use a factory pattern for registration. I also removed the handler for inferior exit events in favour of one for the newly added thread_exit event. That simplified the python file. * Patch 10: This is now using an optional for the filter function return value and is printing the payload directly, if we don't have a filter or no Python support. The documentation changed a lot due to the new way to register filters.
