o2.cpp : patch from digiKam core about scope and state parameters

[cgilles]

Hi,

In digiKam core we host the O2 source code internally to communicate with remote web service and export items from photo collections.

Few days ago, digiKam have been ported to Qt6 (it still compatible with Qt5) and i updated as well O2 library with last code available (previous version dating a lots)

Recently, a student working on ImgUr plugin for digiKam, has restored a small patch that i forget to re-integrate to O2:

https://invent.kde.org/graphics/digikam/-/merge_requests/170/diffs#842297e068b45b02767c92fbe54bbceec08c8ae8

Typically, in some conditions (probably an older Qt5 version), this patch must be applied to communicate properly.

We will re-integrate this patch to the O2 source code from digiKam core.

Best regards

Gilles Caulier
