This series of patches cleans up the handling of the variants in C++.
In a few words: responsibilities have been redistributed where they
"naturally" belong.

  c++: formatting and comment changes
  c++: revamp the support for variants
  tests: enable support for --debug
  c++: remove now-useless operators
  tests: remove useless %defines
  tests: check that using variants is exception safe
