By commenting out the parameter name, we get compile-time checks
Also, we can omit them for slots and Qt will not forward the parameters.
In case we had TODOs next to the code, I kept the Q_UNUSED statements
for now.
- We do not need the return type. If a plugin declares it can handle the
packet it should do so. We don't have any fallback logic in place and
the packet types are namespaced with the plugin IDs anyway.
- Provide a default implementation with a warning, not all plugins need
to overwrite this
The rationale is explained in https://planet.kde.org/friedrich-kossebau-2023-06-28-include-also-moc-files-of-headers/
In case of KDEConnect, it impressively speeds up compilation. Before it
took 390 seconds on a clean build and with this change it took 330 seconds.
This is due to the mocs_compilation having to include the header files
and thus all their headers. Due to the lots of small plugins we have,
this means that the same headers must be compiled plenty of times.
When we include the moc files directly in the C++ file, they are already
available.
## Summary
Add support for Phone side (like in the Android and SailfishOS apps) to telephony plugin.
this requires ModemManager to work.
Call state notifications are currently supported, more capabilities are possible.
Tested on PinePhone but should probably work on every linux Phone with ModemManager.
to test, pair kdeconnect on your linux phone to desktop, and call your phone.
you should get notification on the desktop, telling you that phone call is incoming.
