From 36a8bdbc8417506513207daf4f36533a3d6632f3 Mon Sep 17 00:00:00 2001
From: Timur Pocheptsov <timur.pocheptsov@qt.io>

Subject: [PATCH] OpenSSL: handle SSL_shutdown's errors properly
Do not call SSL_shutdown on a session that is in handshake state (SSL_in_init(s)
returns 1). Also, do not call SSL_shutdown if a session encountered a fatal
error (SSL_ERROR_SYSCALL or SSL_ERROR_SSL was found before). If SSL_shutdown
was unsuccessful (returned code != 1), we have to clear the error(s) it queued.
Unfortunately, SSL_in_init was a macro in OpenSSL 1.0.x. We have to
resolve SSL_state to implement SSL_in_init.
Fixes: QTBUG-83450
