- Cleanup with spec-cleaner
- Use %setup to unpack all archives do not rely on tar calls

- Update to upstream release 2.2.1:
* Reverted a change to GeneralNames which prohibited having zero elements,
due to breakages.
* Fixed a bug in
:func:`~cryptography.hazmat.primitives.keywrap.aes_key_unwrap_with_padding`
that caused it to raise InvalidUnwrap when key length modulo 8 was zero.
* BACKWARDS INCOMPATIBLE: Support for Python 2.6 has been dropped.
* Resolved a bug in HKDF that incorrectly constrained output size.
* Added
:class:`~cryptography.hazmat.primitives.asymmetric.ec.BrainpoolP256R1`,
:class:`~cryptography.hazmat.primitives.asymmetric.ec.BrainpoolP384R1`, and
:class:`~cryptography.hazmat.primitives.asymmetric.ec.BrainpoolP512R1` to
support inter-operating with systems like German smart meters.
* Added token rotation support to :doc:`Fernet ` with
:meth:`~cryptography.fernet.MultiFernet.rotate`.
* Fixed a memory leak in
:func:`~cryptography.hazmat.primitives.asymmetric.ec.derive_private_key`.
* Added support for AES key wrapping with padding via
:func:`~cryptography.hazmat.primitives.keywrap.aes_key_wrap_with_padding` and
:func:`~cryptography.hazmat.primitives.keywrap.aes_key_unwrap_with_padding` .
* Allow loading DSA keys with 224 bit q.
