libsmartcols: bindings via siwg

[ignatenkobrain]

Currently tested and supported only python bindings, but it is easy to add another languages. Now without any documentation, but it is in my plans for the future.

@karelzak, ready for review ;) Without CMake as you wanted. I dont know how to fix problem with

relink `_libsmartcols.la' with the above command before installing it

It works perfectly with creating util-linux RPM.. Docs will come in some days.

I will reopen when I will finish some stuff here.

@karelzak I reworked bindings and now got some documentation and nice feature Table.json() which will return dict by json.loads().

Built documentation looks: https://ignatenkobrain.fedorapeople.org/pylibsmartcols/

Remaining issues:

• installation in shittyci failing due to relink (can't fix myself, out of ideas)
• auto-generate link to C-doc in libsmartcols/docs/python/conf.py.in (will take a look later)
