Rename and change ED25519_keypair_from_seed to ED25519_public_from_private
to be consistent with X25519 API.

Modidy ED25519_sign to take separate public key argument instead of
requiring it to follow the private key.

Issue #3562 describes a problem where a race condition can occur in the
Proxy such that a test "ok" line can appear in the middle of other text
causing the test harness to miss it. The issue is that we do not wait for
the client process to finish after the test is complete, so that process may
continue to write data to stdout/stderr at the same time that the test
harness does.

This commit fixes TLSProxy so that we always wait for the client process to
finish before continuing.

Fixes #3562

Commit 9bfeeef8 made some function parameters const. This actually broke
the pyca-cryptography tests. The discussion in #3360 considers this to
actually be a problem with pyca-cryptography not an OpenSSL issue (they
replicate some of our header file contents which then causes function
prototype mismatches). This commit updates the pyca-cryptography version
to pull in their fix for this issue and make our external tests pass again.

Commit bd990e25 changed our handling of alerts. Some of the BoringSSl
tests were expecting specific errors to be created if bad alerts were sent.
Those errors have now changed as a result of that commit, so the BoringSSL
test config needs to be updated to match.

If we have an assert then in a debug build we want an abort() to occur.
In a production build we want the function to return an error.

This introduces a new macro to assist with that. The idea is to replace
existing use of OPENSSL_assert() with this new macro. The problem with
OPENSSL_assert() is that it aborts() on an assertion failure in both debug
and production builds. It should never be a library's decision to abort a
process (we don't get to decide when to kill the life support machine or
the nuclear reactor control system). Additionally if an attacker can
cause a reachable assert to be hit then this can be a source of DoS attacks
e.g. see CVE-2017-3733, CVE-2015-0293, CVE-2011-4577 and CVE-2002-1568.
