QDoc: Move global variables out of main.cpp

This change moves most of the global variables out of main.cpp, and
into the new qdocglobals class, with getter and setter functions for
each variable.

It also introduces the basic structure for autotests for QDoc.

The motivation is to increase the testability of QDoc, as well as to
simplify any future refactoring.
