Matej Cepl 058448ea08 - Update to 1.1.1: ...

- Fixed regression where the serialization and deserialization
    functions could be inadvertently turned into instance methods with
    an unexpected argument signature, namely when pickle.dumps and
    pickle.loads are the pure Python version as is the case in pypy.
  - Reworked the means by which values are serialized and deserialized
    from backends, and provided for custom serialization of values.
    Added the CacheRegion.serializer and CacheRegion.deserializer
    parameters which may be set to any serializer.
  - Serialization and deserialization now take place within the
    CacheRegion so that backends may now assume string values in all
    cases. This simplifies the existing backends and also makes custom
    backends easier to write and maintain.
  - Additionally, the serializer is now applied to the user-defined
    value portion of the CachedValue and not to the metadata or other
    portions of CachedValue object itself, so the serialized portion is
    effectively a "payload" within the larger CachedValue structure that
    is passed as part of the larger string format. The overall format is
    a separate JSON of the cached value metadata, followed by the
    serialized form. This allows for end-user serialization schemes that
    are hardwired to the values themselves without the need to serialize
    dogpile's internal structures as well.
  - Existing custom backends should continue to work without issue; they
    now have the option to forego any separate serialization steps, and
    can also subclass a new backend BytesBackend that marks them as
    a backend that only deals with bytes coming in and out; all internal
    serialization logic from such a backend can be removed.
