* Refactored much management of the BLOCKED and EOF flags into ChanRead() thendgp2014-05-131-1/+1
| | | | | | | 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.

| | | | | | | compressing transforms when the amount of data to be written is one buffer's-worth; problem was particularly likely to occur when compressing large quantities of not-very-compressible data. Many thanks to Piera Poggio (vampiera) for reporting.
