Refactored much management of the BLOCKED and EOF flags into ChanRead() then

began repairing some of the logic about them. 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.
