Description

Issue originally found by Petr Matousek

When producing a message with a routing key longer than 255 characters, the Qpid python client hangs / spins indefinitely. There is seen mutual recursion around check_error/sync/close in the endpoints.py that leads to memory allocation failure.

In the previous python-qpid versions following exception were reported: CodecException: Cannot encode 256 as uint8

Steps to Reproduce:
1. ./spout "amq.fanout/$(printf 'X%.0s'

{1..256}

)"
2. spout execution never ends

Actual results:
The sender execution never ends when subject longer that 255 characters is used.

Expected results:
Encoding exception reported.
