Fix: Reject URIs with embedded NUL bytes - #98

Conversation
This patch adds checks at each place in the Cython layer that accepts a URI (broker endpoint or queue URI) and verifies that there is no embedded NUL byte in the the URI string. If the URI string does contain an embedded NUL byte, an exception is raised. This patch also adds several new tests to verify this. Signed-off-by: Patrick M. Niedzielski <pniedzielski@bloomberg.net>

If the URI string does contain an embedded NUL byte, an exception is raised. This patch also adds several new tests to verify this. In principle, we are okay to rely on the change in the last patch to prevent this bug, but it is better to be explicit about what we consider an error at each layer, in case the code ever changes.

This pull requests adds checks in two places for URI strings with embedded NUL bytes in them: at the Cython layer, and at the Python layer. This ensures that the C++ layer, which traffics in NUL-terminated strings, does not accidentally treat such a string as shorter than the Python code intended. It also includes tests to verify that if embedded NUL bytes are found, exceptions are raised.
