We use kdeconnect-version.h in several places and therefore it needs to be in the include path. We currently do this by setting target_include_path in a few places. Replace this with an interface library that we can link against that sets up the correct include path. IMO it is cleaner this way.
This automatizes the generation of logging categories so a
kdeconnect-kde.categories is generated and installed to
/usr/share/qlogging-categories5/ so kdebugsettings can use it.
Also, sets the default logging level to Warning. So now the logs
of users won't be filled with debug messages but they can
modify the configuration easily with kdebugsettings.
clazy was complaining that the class had copy constructor but no assignment operator, which is usually suspicious
This is a bit of behaviour change though, since now m_payloadTransferInfo is also copied, which before wasn't, not sure if this is actually a good or a bad thing
Device::statusIconName depends on isReachable() and isTrusted()
Not sure how the property is used but it's good that they have a NOTIFY is defined if it's needed for completion
## Summary
LanLinkProviderTest fails on Windows. This patch fixes that.
I believe the root cause is that we are using a shared UDP socket to listen for identity broadcasts both in the LanLinkProvider and in the test. Apparently this works on Linux, but on Windows the LanLinkProvider picks up its own identity packet and pairs with itself.
This patch gives a parameter to LanLinkProvider to allow it to listen and broadcast on different ports, then uses that ability in the test to make the test pass on Windows.
## Test Plan
### Before:
lanlinkprovider test fails, first because it can't bind its UDP listener socket, and then because Windows seems to handle shared sockets differently than Linux, so the UDP broadcasts were not reaching the test's listener.
### After:
lanlinkprovider test seems to pass reliably both in my Windows VM and in the CI
