Tests iogt-2.* now fail because they've been crafted as experiments recording the fine detail of reflected channel driver calls, and fixing the management of channel flags is changing that. zlib-8.5 also needed adjustment to reflect that an EOF set must come with an empty string read when flags are functioning properly.
