Add optional message to TLSError
TLSError now takes an optional error message. OpenSSLContext has been updated to send out one, and calls to SWIFT_LOG have been removed from it for anything but setCertificateChain. OpenSSLContext::handleDataFromApplication misinterpreted the return code of SSL_write, triggering an onError in cases where more network I/O was required. Test-Information: Unit tests pass on Debian 9 Server test code no longer emits undesirable warnings to stderr on macOS 10.14. Change-Id: If0f932693361ef9738ae50d5445bfb4d3ed9b28f
