Pure-Python implementation of a Python 3-like bytes object for Python 2.

Why do this? Without it, the Python 2 bytes object is a very, very
different beast to the Python 3 bytes object.

        bytes(iterable_of_ints) -> bytes
        bytes(string, encoding[, errors]) -> bytes
        bytes(bytes_or_buffer) -> immutable copy of bytes_or_buffer
        bytes(int) -> bytes object of size given by the parameter initialized with null bytes
        bytes() -> empty bytes object

        Construct an immutable array of bytes from:
          - an iterable yielding integers in range(256)
          - a text string encoded using the specified encoding
          - any object implementing the buffer API.

        Decode B using the codec registered for encoding. Default encoding
        is 'utf-8'. errors may be given to set a different error
        handling scheme.  Default is 'strict' meaning that encoding errors raise
        a UnicodeDecodeError.  Other possible values are 'ignore' and 'replace'
        as well as any other name registered with codecs.register_error that is
        able to handle UnicodeDecodeErrors.
