Subject: [PATCH 2/2] Add CRC32 tests (crc32_test)
This commit includes a CRC32 test (crc32_test). This tests are important
since some architectures may want include CPU dependent optimizations for
CRC32 algorithm like using vector instructions and we may want to
validate those.

From d09bb1ab8ef9bb91457c0ead09589e8807489260 Mon Sep 17 00:00:00 2001
From: Ondrej Dubaj <odubaj@redhat.com>
Date: Thu, 6 Aug 2020 08:09:53 +0200
Subject: [PATCH] Permit a deflateParams() parameter change.
This change allows a parameter change even if the input data has
not all been compressed and copied to the application output
buffer, so long as all of the input data has been compressed to
the internal pending output buffer. This also allows an immediate
deflateParams change so long as there have been no deflate calls
since initialization or reset.
