modtool: gr-modtool overhaul GSoC 2018
This commit contains all the changes done during the 2018 GSoC
"gr-modtool overhaul".
Changes include:
- Rewrite of gr-modtool based on Python Click
- Split of gr-modtool in cli and core
- Adherence to new GNU Radio 3.8 API for OOTs
- Pylint improvements
- Py3k and Py2k compatibility
This feature is merged in a squash-merge due to big refactoring
on the head and base branch and the impossibility to unclutter both.
