[lipstick] Don't construct the embedded ConnectionSelector window by default. Contributes to JB#49715

[lipstick] Remove x-nemo-suppress-display-on notification hint. Fixes JB#51376

See merge request !158

Introduced with commit e9c29a3d / JB#37024 to allow device lock
mode to have notifications that are displayed but don't turn on the
screen.

This can be now achieved with public visibility hint and I didn't
find any remaining usage.

Explicit notification app name

See merge request !157

Reverting some parts of commit 6c5d366f, the app_icon is not really
a standard hint, only the same named parameter is standard.
We don't gain much from having a duplicated extension.

Also to help the UI side, added icon source property to indicate
how reliable the value really is.

We have some heuristics in NotificationManager for digging out the app
name all the way from d-bus sender process binary to guessing the
.desktop file name and using what's available there, falling back to
process binary if no .desktop file available.

Since that can go wrong, especially without a .desktop file even
existing, let's expose what the notification really included.

The database schema is slightly altered. The earlier times seemed
to be enough in the past, last time 2017, so didn't bother
keeping those update paths.

[lipstick] Default notification urgency should be normal. Fixes JB#51339

See merge request !156

0 as default was giving low.

[lipstick] Don't show notification popups for low priority. Contributes to JB#51197

See merge request !154

Why bother user if it's low priority already. Transient ones still
just in case.

[lipstick] Expose also notification actions that trigger only d-bus signal. Contributes to JB#44716

See merge request !153

[lipstick] Remove some obsolete notification properties. Fixes JB#51045

See merge request !152

Support Do Not Disturb mode. JB#50221

See merge request !151

Follows DConf key /lipstick/do_not_disturb.
When set on, the notifications will not play sound or vibra, and only
critical notifications can turn the display on.

file:// prefix removal commonly works except when it surprisingly doesn't.

Jb50821 transient notifs

See merge request !150

Currently, marking a notification as transient means it will be
closed immediately after it is presented to the user in the
notification preview. However, it should also be prevented from
appearing in the notification list even while the preview is shown.

[lipstick] Add support for the image-data role. Contributes to JB#45997

See merge request !149

[lipstick] Remove handling of the x-nemo-hidden notification hint. Contributes to JB#50443

See merge request !148

Add MS Teams and Messenger Lite to androidnotificationpriorities

See merge request !146

On the consumption side return the image as a data URL from image-path
so it can be entered as the source of an Image in an interoperable way.

Set summary/body instead of previewSummary/previewBody.
Set transient where necessary.
