    registry: allow plugin and feature filter funcs to call registry API

    Don't keep the registry locked whilst iterating over the plugins
    or features with a filter function. This would deadlock if the
    callback tried to access the registry from the function. Instead,
    make a copy of the feature/plugin list and then filter it without
    holding the registry lock. This is still considerably faster than
    the alternative which would be to use a GstIterator.
