httppeer: use util.readexactly() to abort on incomplete responses Plain resp.read(n) may not return exactly n bytes when we need, and to detect such cases before trying to interpret whatever has been read, we can use util.readexactly(), which raises an Abort when stream ends unexpectedly. In the first case here, readexactly() prevents a traceback with struct.error, in the second it avoids looking for invalid compression engines. In this test case, _wraphttpresponse doesn't catch the problem (presumably because it doesn't know transfer encoding), and the code continues reading the response until it gets to compression engine data. Maybe there should be checks before the execution gets there, but I'm not sure where (httplib?)
