Now that csync builds as C++, this will avoid having to implement
functionalities needed by csync mandatorily in csync itself.
This library is built as part of libocsync and symbols exported
through it.
This requires a relicense of Utility as LGPL. All classes moved into
this library from src/libsync will need to be relicensed as well.
Remove all configure_files:
- Move all tests to cpp files
- Use the QTEST_MAIN macro instead of a generated main.cpp
- Include test*.moc in the cpp to let CMAKE_AUTOMOC call moc
- Pass info through add_definitions instead of generating oc_bin.h with them
This makes sure that build errors points to the original test source
file instead of the generated one in the build directory to be able to
jump and fix errors directly from the IDE's error pane.
