Summary:
The use of Q_FOREACH is advised against (https://doc.qt.io/qt-5/qtglobal.html#Q_FOREACH) since Qt 5.7 and will eventually be removed from Qt.
I replaced all occurrences with the range-for loop introduced in C++11 (except for the one in daemon.cpp in deviceIdByName which might have a bug / typo in it).
I added const to the container or casted it with qAsConst when appropriate to avoid unnecessary copies.
(This is my first submission. I did all the unit tests, and they all passed but I don't know how to show it here.)

KDE Connect runs, and the bluetooth service gets published in the SDP
(service discovery protocol), which other devices use to determine what
services are available.
The getPairedDevices() method in the link provider class uses D-Bus to get
the list of paired devices, since Qt doesn't have a method giving that
information. As a result, that part of the code only works on Linux.
