* Don't try to use the previous malloc functions.
The default malloc is CRYPTO_malloc which calls the custom ptr you provided, so it just recurses forever.

Trying to be too specific about why key loading fails is very difficult
when you're using the same logic across DH, EC, RSA, and DSA. This makes
it less fancy.

If pyca/cryptography sees any errors on the error stack during its own
initialization it immediately raises InternalError and refuses to
proceed. This was a safety measure since we weren't sure if it was
safe to proceed. However, reality has intervened and we have to
bow to the god of pragmatism and just clear the error queue. In
practice this is safe since we religiously check the error queue
in operation.

* switch the PEM password callback to a C implementation
Calling from C to Python is fraught with edge cases, especially in
subinterpreter land. This commit moves the PEM password callback logic
into a small C function and then removes all the infrastructure for the
cffi callbacks (as we no longer have any)
* review feedback and update tests

* enforce password must be bytes when loading PEM/DER asymmetric keys

* Backport DH_check from OpenSSL 1.1.0.
OpenSSL 1.0.2's DH_check considers the q parameter, allowing it
validate more generators and primes; however, OpenSSL 1.1.0's DH_check
includes code to handle errors in BN functions, so it's preferred.
* Wrap DH_Check when using OpenSSL 1.1.0 or higher.
* Adding DH_CHECK_* values missing from older OpenSSLs
* Defensively guard DH_CHECK_* definitions with ifndef.
This will prevent duplicate definitions when LibreSSL supports a
version of DH_check that can return these.
* Document the OpenSSL of origin for the DH_check code

* Use static callbacks with Python 3.x again
Static callbacks were disabled for Python 3.5+ to work around an issue
with subinterpreters, locking callbacks and osrandom engine. Locking
callback and osrandom engine were replaced with a C implementations in
version 1.6 and 1.7.

* remove CCRandomGenerateBytes path and update getentropy to work on macOS
This change allows us to test all the engines in our CI:
* getentropy (tested by macOS sierra)
* getrandom (tested on several linux builders)
* /dev/urandom (tested on FreeBSD, OS X 10.11 and below, & older linux)
* CryptGenRandom (tested on windows builders)
I also fixed bugs preventing compilation in the getentropy code
* getentropy() returns int and is restricted to 256 bytes on macOS, too.

* Add error reporting and fail for EAGAIN
Add error reporting strings for various error cases. This gives us much

SYS_getrandom() EAGAIN is now an error. Cryptography refuses to

seeded yet.

* Start of OpenSSL DH backend implementation
* Supporting DH in MultiBackend
* DHBackend has dh_parameters_supported method
* Removed DHParametersWithNumbers and DHPrivateKeyWithNumbers from documentation
* Removed ExchangeContext. exchange is a method of DHPrivateKeyWithSerialization
* PEP8 fixes
* Fixed TestDH.test_bad_tls_exchange
* Fixed generate_private_key reference in dh documentation
* test DH multibackend support
* testing DH coversion to serialized
* Validating that we receive serialized class in test_generate_dh
* Testing DH exchange symmetric key padding
* struct DH is now opaqued
* PEP8 fixes
* Testing load_dh_private_numbers throws ValueError when DH_check fails
* Using openssl_assert
* Passing keywords arguments in DH key exchange example
* test_dh::test_bad_tls_exchange now uses pre calculated parameters
* TestDH - Add test that the computed secret is equivalent to the definition by comparing with secret computed in pure python
* Add missing generator parameter to DHBackend interface docs.
* Include parameter type in DHBackend abc docs.
* Add docs for dh.generate_parameters function
* Remove the dh Numbers section, and move the DHNumbers class docs to where they are first used.
* Add note of big endian byte packing to DH exchange method.
* DH documentation updates.
Add single sentence overview with wikipedia link.
Add paragraph on assembling using Numbers objects.
Add link to backend interface docs.
First section was all indented, I think by mistake.
* Add exchange method to DHPrivateKey abstract base class.
* Small tweaks to DH documentation - remove Provider.
* Add endian to dictionary
* Use utils.int_from_bytes in test_tls_exchange_algorithm
* Removed duplicate line
* Change dh.rst exchange algorithm from doctest to code-block
The example in the Diffie-Hellman exhange algorithm is using
2048 bits key. Generating the parameters of 2048 takes long
time. This caused the automated tests to fail. In order to
pass the tests we change the example to code-block so it
will not run in the doc tests.
* Fix dh docs
* Document the generator in DHBackend relevant methods
* Fix dh tests
* use DHparams_dup
* Fix key type to unsigned char as expected by DH_compute_key
* Validate that DH generator is 2 or 5
* test dh exchange using botan vectors
* group all numbers classes
* Simplify _DHPrivateKey
* Rename test with serialized to numbers
* Move bad exchange params to external vector file
* update exchange versionadded to 1.7
* Make key_size bit accurate
* Change botan link
* Added CHANGELOG entry
