Add a macro for testing assertion in both debug and production builds
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.
