PythonQt Code

removed methods that are not present on all platforms/configurations

applied patch from Uwe Siems (print correct file location in parser)

fixed QTimer wrapping for Qt 5.12

enable QMutexLocker (but __enter__ and __exit__ don't work yet due to PythonQt class wrapper implementation...)

enable QThread (it was removed long time ago but makes sense now that PythonQt support multi-threading)
removed template function on QQmlEngine

don't print omitted rvalue methods, we just don't want to wrap them

applied patch provided by Uwe Siems

use C++11 {} initializer for returnValue

fixed problematic self deletion without having the GIL and while iterating the loop

added missing GIL scope
