(MODPYTHON-155) Modifications to handler and filter lists so thatreferences can be maintained back to parent handler of a handler/filterwhich was registered dynamically. This is necessary within the scheme ofhow the new module importer works. Specifically, where a directory isn'tspecified when adding a handler or registering a filter, the directoryassociated with the parent up the chain has to be used instead. In the oldimporter it was relying on fact that directory of parent had already beenadded to the Python sys.path, although this didn't actually work reliably.The new module importer doesn't add directories to sys.path and so the needto properly work out directory associated with a parent so that it can beused when required.
