QDoc: make the Config a parameter instead of a global

This shall make it easier to test QDoc, by making mocking possible.

This change moves the instantiation of Config:: to reside inside main(),
so that it can be passed as a parameter where it is needed.

This object is then passed to QDocCommandLineParser::process(), so that it
can be changed via the object itself rather than via statics/globals. This
improves the testability of the QDocCommandLineParser class, as the Config
object can easily be mocked.

This change also replaces a couple of foreach() uses in main.cpp with
range-based for.
