localrepo: move filtername to __init__ This is obviously an instance attribute, not a type attribute. The modern Python style is to use __init__ for defining these. This exposes statichttprepo as inheriting from localrepository without calling its __init__. As a result, its __init__ defines a lot of variables that methods on localrepository's methods need. But factoring the common bits into a separate class is for another day.
