We operate on a QSharedData object and thus can trivially make a copy. We generally don't use use const refs as return values in KDE APIs unless there is a compelling reason to do so
KDNSSD only works with Avahi (so, only on Linux) while mdns.h is a
header-only library [1] that implements mdns from scratch and should
work on all platforms.

We can always provide a function rather than a value.
This is what we do in most places already and is consistent with the
rest of KDE.
This gets compiled to the same code.
```cpp
explicit QLoggingCategoryMacroHolder(const QLoggingCategory &cat)
{
if (IsOutputEnabled)
init(cat);
}
explicit QLoggingCategoryMacroHolder(QMessageLogger::CategoryFunction catfunc)
{
if (IsOutputEnabled)
init(catfunc());
}
```
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.
Overriding and defaulting them in the header doesn't make sense
For the dbus interfaces, we don't have any reasources to clean up or memory to be released. Meaning we can drop those lines too
- Using QLatin1String when concatinating strings is faster, because they
are more lightweight. For the resulting string, we need to allocate
new memory anyway
- Use QLatin1String overloads where they are provided by Qt APIs
- Just use const char* for log messages, the quoting of QStrings is not
needed
- Make sure to reuse string results when possible
- 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.
This makes it easier to read, because we do not have to handle a list of
files that get added to the targets. In other KDE projects, we also
prefer the target centric approach.
In case one wants to reuse the same category in multiple places, it
would be best to create a small static lib. But for now, this is not
needed.
Change some optional dependencies from being optional to being mandatory
or being mandatory but behind on-by-default cmake flags. Eg: instead of
only compiling Wayland support if we find the appropriate libraries, we
always require the libraries unless the user specifies WITH_WAYLAND=OFF.
Optional libraries are hard to discover by packagers (since they don't
see an error once we add them) and create lots of possible build flavors
with a different features that can confuse users.
In theory we support Qt 5.6 (because of SailfishOS) but in practice we are not checking that in the CI so probably we broke the compatibility long ago. Also, I don't think anyone is using this code in SailfishOS, so we can greatly simplify the code by requiring Qt 5.15 or later.
Instead of always doing so on MacOS, do it only when we get a
DatagramTooLargeError. On MacOS, the size is limited only for
broadcast but not for unicast.
Since sockets are buffered `QIODevices` we can use `canReadLine()` to check
if we have a full line, instead of using a custom `SocketLineReader` class
(and the copy-pasted `DeviceLineReader` in the Bluetooth backend).
We can also loop through all the lines instead of queuing calls to `dataReceived`.
And we don't need transactions.
When receiving two files with the same name, the first file might not be
saved to disk already when we have to decide the name for the second if
we do it too early.
BUG: 470078
argument
Previously the BluetoothDeviceLink::certificate() method was returning a
value initialized object which I believe default initializes the object.
However, Clang throws a build error at this because QSslCertificate has
explicit constructors. This change uses one of those constructors and
uses value intialization to default construct/initialize the argument
for it. It fixes the build and hopefully doesn't break anything since
this is a TODO anyways!

The main thing it provides over QNetworkAccessManager is integration
with the CookieJar and using kio-http, but since we jsut exchange bytes
from another local device that's not interesting for us
This whole code was no-op: it enumerates network interfaces, enumerates
its IP addresses, but does not change the address of broadcast UDP
packet, sending it only via default route/interface.
Bind the socket to IP addresses of the interfaces to fix the issue.

This is the proper way to communicate progress.
It has Plasma show the file name in case of single files
and "n of m files" as before for multiple files.
On FreeBSD 12 or later, a new routing strategy is introduced, which
prevents broadcast using 255.255.255.255.
Thus, we need to explicitly send the broadcast to each network
interfaces.
Here the commit can simply reuse the code for Windows.
