JNI: Support QStringList as a parameter of native functions

Since we support QString and QList specializations, we should also
support QStringList directly. That's a bit more involved as we need
to specialize the code path for QString, which is not convertible to
or from jobject. But once we have mapped the type to jstring it
follows the implementation for lists of objects.

We now need to generate temporary local references when
converting a QString to a jstring, so manage a local frame. We do
so explicitly in chunks of 100 local references.
