No way to enroll multiple fingers for identification

[Marco Trevisan (Treviño)]

* Impact

This is the continuation of bug #1865845.

In g-c-c user panel, it is not possible to enroll more than one finger for authentication.

* Test Case

1. enroll fingerprint in gnome-control-center
2. close the dialog
3. click it again to enroll another finger
4. it shows a dialog requiring you to delete your fingerprints

* Impact

As per this, GNOME design has produced some artwork that we want to implement to fix all these issues:
 - https://gitlab.gnome.org/Teams/Design/settings-mockups/-/issues/18

There will be few new strings, although most of the action events are already covered by the fprintd translations.

UI will change quite a lot, but the current documentation [1] should not be affected by the change, being quite generic, but in case it might be updated to be clearer. The change are important improvements and oem request so believe it's right to carry over as a SRU and considered as hardware enablement

The new strings are already translatable on launchpad and the translators mailing list has been notified, hopefully we can get some coverage for the new UI in time for the LTS .1 langpack refresh

Tested in gnome-control-center 1:3.36.4-0ubuntu1, using the synaptics sensor in a recent ThinkPad.

Multiple fingerprints can be enrolled, it's still possible to remove the fingerprints properly, identification at unlock/login phase still works properly.

[frank (frankwu)]

tested the package,

gui-bug seems to be fixed, i can add fingerprints and delete them. but it looks like they are not registered the right way...i can only login with the first finger i added (tried also reboot and second is still listed in gnome-control-center)....the other one added with the new gui is not recognized...can i check if the fingerprints are added right?

unlock seems to need additional Patch from gnome-shell (gnome-flashback session)

strange is that the dialog is not movable (titlebar-dragging), is this intented?

[frank (frankwu)]

Tried with fprintd-list (both listed), fprintd-verify (only first matching) and deleting/new assigning (same result) with my closed source goodix 530c. I guess it's a driver-bug...not gnome-control-center one.

Sorry for the noise
