Access control tests

Add test cases for the join_access_control governance setting and for
the access control plugin check_create_ and check_remote_ hooks,
using a wrapper plugin that simulates failure for each of these,
to test the DDSI integration with the access control plugin.
This commit also contains fixes for:
- an assert on DDS_RETCODE_OK in dds_create_reader and
dds_create_writer that cased the application to terminate in case
creation of a reader or writer is not allowed by security
- do not match a proxy reader that has the 'relay_only' set to
true, which is currently unsupported
