Fix glue.ldbd XML parsing under Python 3
This MR adds a new test script test_ldbd.py
which includes a single test to check the XML parsing using pyRXP. The other commits then fix the various failures that occur because glue.ldbd
was never properly updated to Python 3.
This change was developed in collaboration with @robert.bruntz.
EDIT: fixes #24 (closed)
