For this, simplify the implementation of the notch effect at the top by
assuming a flat monochrome background and just drawing the notch on top,
rather than masking it out with an opacity mask shader effect.

This adds the correct rich text, but doesn't fix interaction yet, as the
shader effect opacity mask eats the mouse events here.

This will make it show up as application instead of System Service in the notifications KCM

Android only so far, as we don't have KNotifyConfig for Plasma Mobile yet
I think. This also adds support for showing disruption notifications
on the lock screen, if supported by the platform. That depends on pending
KNotification patches though.

Unlike QAndroidIntent::putExtra, this one interoperates with Android's
types. The Qt one just serializes the value using a QDataStream and puts
that into a Java byte array, and thus is entirely useless if you want to
interact with anything not using Qt (which essentially is everything on
Android).

This avoids boilerplate code, and allows us to use properties as such
rather than representing them as functions. Read-only so far, as we only
use this for constants, but the concept should work for writable and
non-static properties as well, if we ever need that.

This however requires C++17 inline variables, which isn't a problem as we
only need this on Android, and there the compiler is new enough.

At that point they provide no value anymore.

Enables notification configuration on Plasma systems, and gives us more
control over the notification channel on Android.

Also, add a manual test rig for delay notifications.

This also removes the last traces of KPublicTransport::Departure, and
extends the unit testing of LiveDataManager.

This avoids losing the realtime information you had just seen on screen
again, just to re-fetch them by the regular polling (if enabled).

Besides reducing code duplication further, this fixes a number of issues:
- Polling failure are now considered correctly when calculating the next
poll interval.
- Multiple disruptions for a single journey are now shown in a single
notification.
- Still active notifications are updated when new information become
available, rather than creating a new one.
- Stored live data is now loaded on demand rather than on startup.

This will be a lot more detailed, and also covers cancellations. It will
replace the primitive implementation in LiveDataManager shortly.

Reduces code duplication a bit, and more importantly allows to unit test
this now.

Nowadays that is easily available on Android.

Less duplicated code, and less code that is hardcoded to train
reservations.

This is now accessible for unit tests and exporting, with less duplication.
LiveDataManager has yet to make use of this though.

Helps to make it properly unit-testable, in preparation for some larger
changes in here.

Also, implement importing and exporting of settings.

With this gone we can rename the departure types in KPublicTransport
without breaking source compatibility.

This resulted in no logo being displayed at all in some cases.
