* Add support for AES XTS
We drop the non-byte aligned test vectors because according to NIST
http://csrc.nist.gov/groups/STM/cavp/documents/aes/XTSVS.pdf
"An implementation may support a data unit length that is not a
multiple of 8 bits." OpenSSL does not support this, so we can't
use those test vectors.
* fix docs and pep8
* docs fix
* the spellchecker is so frustrating
* add note about AES 192 for XTS (it's not supported)
* docs work
* enforce key length on ECB mode in AES as well (thanks XTS)
* a few more words about why we exclude some test vectors for XTS

* add blake2b/blake2s support for hmac
This was a bug, but it turns out the noise protocol suggests using the
HMAC construction with BLAKE2 (rather than BLAKE2's own keyed
functionality) for a few reasons, so we should support it.

* Test for leaking memory in EllipticCurvePublicNumbers.public_key()
* Fix the memory leak
As far as I can tell, from spelunking in the OpenSSL source (as you do), EC_KEY_set_public_key_affine_coordinates doesn't take ownership of "x" or "y". https://github.com/openssl/openssl/blob/master/crypto/ec/ecp_smpl.c#L362-L420 is the place in the source I found that actually uses "x" and "y".
* Unused imports

* move MACContext to mac.py and eliminate interfaces.py finally
* improve title
* re-add and deprecate interfaces.MACContext
* use pytest.warns instead of deprecated_call
The pytest docs insist that deprecation warnings are handled differently
and that you should use deprecated_call, but this works so okay then

* add libre so I can see the error
* add the libre error needed and refactor error handling a bit
We were historically matching on lib + func + reason, but func is
somewhat unstable so now we match on lib + reason only. Of course, in
this case libressl changed both lib and reason so it wouldn't
have mattered. All error handling from the error queue in
openssl is an illusion
* fix a typo, probably an unneeded branch
* review feedback
* refactor tests to support libressl
insert additional rant about libre here, although admittedly these tests
were assuming stability where openssl itself guarantees none
* better assert, fix flake8

* postpone GCM authentication tag requirement until finalization
Add a .finalize_with_tag() variant of the .finalize() function of
the GCM context. At the same time, do not enforce the requirement
of supplying the tag with the mode ctor. This facilitates
streamed decryption when the MAC is appended to the ciphertext
and cannot be efficiently retrieved ahead of decryption.
According to the GCM spec (section 7.2: “Algorithm for the
Authenticated Decryption Function”), the tag itself is not needed
until the ciphertext has been decrypted.
Addresses #3380

* disallow delayed GCM tag passing for legacy OpenSSL
Old versions of Ubuntu supported by Cryptography ship a v1.0.1 of
OpenSSL which is no longer supported by upstream. This library
seems to cause erratic test failures with the delayed GCM tag
functionality which are not reproducible outside the CI.
Unfortunately OpenSSL v1.0.1 does not even document the required
API (``EVP_EncryptInit(3)``) so there is no by-the-book fix.
For backends of version 1.0.1 and earlier, verify the GCM tag
at the same stage as before.
Also, indicate to the user that late passing of GCM tags is
unsupported by throwing ``NotImplementedError`` for these backend
versions if
- the method ``finalize_with_tag()`` is invoked, or
- the mode ctor is called without passing a tag.
Unit tests have been adapted to account for different backend
versions.
