[transfer-engine] Avoid excessive notification action updates. JB#51671

See merge request !20

When there are rapid consecutive action name changes (due to the auto-
generated action name being different each time a progress notification
is created), this confuses the UI as it needs to rebuild the action
data, and by the time the user triggers an action, it may already have
changed the UI to refer to a different action underneath. To avoid
this, just use the same action name each time.

[transfer-engine] Add 'cancel' action to transfer notifications. JB#50340

See merge request !18

When a transfer is canceled, the transfer id is removed from the
activity monitor. Any cleanup/finish actions after that should not
trigger warnings like this:

"void ClientActivityMonitor::activityFinished(int) Could not find
matching TransferId. This is probably an error!"

The ordering is important in QtDBus 5.6+.

When the transfer is ongoing and supports the cancel method, add
a 'cancel' action to the notification.

Note the progress notification is only shown in the Events, and not
the notification preview.

Update DbManager::mediaItem() to set some more of the MediaItem
properties in the returned object.

Notifications

See merge request !17

- Set summary/body instead of previewSummary/previewBody.
- Notification previews are now shown by default, so explicitly
disable them if required for existing behavior.
- Use same group for all notifications.

Also use same icon for all notifications.

Use macros, not hardcoded paths.

Use of these defines were removed from the spec file a long time ago but
for some reason the defines were left in place. Remove them.

Third party translation example docs + cosmetics

That is, plugins should really handle translations themselves.
Also renamed finnish example translations to have '-' separator for
locale which the code was really trying to use and is the common
naming.
