This moves the UserAccounts panel to a page in the System panel.
This simplifies a lot of the existing code in the UserAccounts panel.
I did minimal changes to the sub dialogs so that those can be touched
in following changes, making it easier to review this one alone.
The main panel widget is now CcUsersPage, and is an AdwNavigationView
widget that has a default "current_user_page" page. Each page is a
CcUserPage (careful with the one-character difference between these
two classes).
Each CcUserPage has an associated ActUser object.
Implement the new designed interface for fingerprint enrollment, so that the
dialog is now based on a stack of views:
- A list of devices to choose (shown only if multiple are available)
- A gallery of enrolled prints available where manage them
- An enrollment progress view when enrolling a new finger
Move part of the logic into a new FingerprintManager (to manage gdbus proxies
generated via gdbus-codegen) that is created when configuring the current
user and that tracks the devices states, while move most of the UI into a new
CcFingerprintDialog that does all the operations in async way.
Due to fprintd lack of APIs, there are few features missing, compared to
the final design (none is a regression):
- Identify the finger when the enroll dialog is visible
- Delete a single fingerprint
- Highlight the finger when the sensor is touched during enrollment
- Add customized labels to fingerprints
- Devices hotpluging
However most of the code has been written considering these, and so they could
be easily implemented in future re-iterations once newer APIs are defined for
such bits.
