Please port to python3
As Python 2 is going End Of Life soon, please consider porting all code away from it and to Python 3.
I see there's already been some efforts of moving towards python3 in master, but I could spot atleast the following which seems like they need attention:
- libgda-report/RML/trml2html/
- libgda-report/RML/trml2pdf/
Running 2to3 libgda-report/RML/trml2*/*.py
might give a good indication for a start of this work.
