This adds tests for mostly "send_destination_prefix" cases
and some "send_destination" cases.

The general test case is:
- addressed recipient is running and owns a name;
- a message is sent to the name owner;
- the response is checked for allow/deny (method return/error).
Each test case is executed both for primary and queued ownership.

The tests include:
- checking send allow/deny for names and namespaces, including nesting;
- checking send allow/deny for neighbour names;
- checking send allow/deny for names/namespaces+interface+member.
