From 7ea93aa35e8a521d68f7fab44d46590210f637b2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] openssl: add log_openssl_errors()
Add a macro to log all errors in the openssl 'thread error queue'.
This consolidates all the openssl-generated errors to return -EIO and log at
debug level.
Also add a 'invalid' test in test-openssl, to allow manual verification that
the openssl error(s) are logged.
(cherry picked from commit 60696b22d96d0c27680400818672e16f8bb2d53b)
