Getting the values from a QMultiMap() returns a list, but not the same
on consecutive calls. Thus calling it twice to get the iterators will
yield different lists, causing the iterator to fail.
Fixes a segfault when destructing the logger.

rbutil uses several components from the utils folder, and can be
considered part of utils too. Having it in a separate folder is an
arbitrary split that doesn't help anymore these days, so merge them.
This also allows other utils to easily use libtools.make without the
need to navigate to a different folder.
