We fade out the authentication prompt when a user successfully
logs into a user session. We reset it and fade it back in when
the user switches back to the login screen VT.
The problem is, we only fade it back in if the auth prompt status is
VERIFICATION_SUCCEEDED. It's possible for it to be NOT_VERIFYING
if the authprompt gets reset for some other reason in the interim.
This commit changes the check to be more precise. We now only skip
the fade-in, if we're already faded in, and we only skip the reset if
we're already reset.

If the login screen actors aren't placed at pixel
boundaries then they will show up blurred with fuzzy
text.
This commit ensures all actor allocations are floored
to integer coordinates.

Currently the menu position below the button means that the menu
can extend to roughly half the screen height before ending up partly
off-screen. This is plenty of space for commonly installed sessions,
but some users have a significantly higher number of sessions in the
list. Move the menu to the side of the button in that case to maximize
the vertical space the menu may take up.

There's some vestigial code for hiding the user list
that runs at the same time its parent is hidden.
Only the parent should be hidden, at this point, so
there's situations where the user list hides and
never comes back.
This commit fixes that, by deleting the vestigial code.

We currently use the setActiveSession method to both mark a menu item as
selected, and also tell gdm about the current session the user selected.
Since gdm is ultimately in charge of the state, we should decouple this
and simply ask gdm to set the session, and have the menu item reflect
what gdm thinks is the current session.
This prevents state getting mismatched and oscillations from happening,
where we get in a loop of constantly telling gdm what the session is.

The problem is caused by '_askForUsernameAndBeginVerification' being
called multiply times. So when we click 'next', the old connected
function will also be executed.
After the login banner is shown and hidden, the first user
in the user list becomes non-reactive. This is because the
banner is given an opacity of 0, but still allocated.
This commit fixes that by hiding the banner explicitly.

Normally when a user uses the login screen to log in, the
login screen gets killed and the user session takes over
the display.
This doesn't happen for wayland sessions, though. Instead,
the login screen gets reset, and the wayland session is started
on another VT.
The greeter proxy object needs to be recreated after this reset,
since it's associated with state no longer coupled to the login
screen after the reset.
This commit moves greeter proxy creation to happen at reset time.

Frequently banner messages are longer than can reasonable
fit in a one column view, which leads to a smooshed layout.
This commit changes the layout to a two column view, with the
banner on the left and the prompt on the right, if the banner
message is long enough that it can't fit well above the prompt.
If there isn't enough space for two columns then we keep the
one column layout but add scrollbars.

The login screen supports showing a banner message which admins
can use to mention login rules or disclaimers.
This message only shows up currently if the user list is enabled.
Most people who want to show a banner message also want to disable
the user list.
This commit moves the banner message to display when the user is
prompted for login credentials instead of when showing the user
list. It also adds a scrollbar if the message is too long.

The login screen is pretty custom full screen container and the standard
layout managers aren't really a good fit for the kind of layout that's
happening. This will be even more problematic with upcoming changes
to login banners, so we need to switch techniques.
This commit moves login dialog over to using a custom allocate handler
that has specific domain knowledge of the parts of the login screen
and where they go.

If the user list is disabled and the user clicks cancel quickly enough
after typing their username, they can get in a state where the
auth prompt gets stuck in the insensitive state.
This is because the login dialog code makes the prompt insensitive
while while pam is processing the provided username, but the prompt
only makes itself sensitive again when it is hidden.
This commit makes it sensitive right before asking for a username again.

When a user logs in to a wayland session, we keep the login screen
running on the X server with the login screen running in a deactivated mode.
This commit makes sure it get reactivated when the user comes back to
the VT (from user switching, logout or just ctrl-alt-f1).

Loading the user list can be expensive, for instance when there is
a large number of users and/or their avatars have to be fetched over
the network. In case the user list is disabled anyway, there is no
point in doing that work just to hide it, so stop doing that.

Right now we queue populating the user list in the middle of setting
up the dialog actors. Of course, the actual population happens some time
later after going back to the main loop.
It's more logical to structure the code so the the actors are
instantiated first in one block and then other things after that.
This commit moves the user list population enqueuing operation to the
bottom of the constuctor.
https://bugzilla.gnome.org/show_bug.cgi?id=721868
In some cases we load the user list after going back
to main loop and in other cases we load the user list
right away (depending on if accounts service is ready).
In the case we load the user list right away we cause a
traceback because loading the user list forces a reset,
which then tries to reset actors which aren't instantiated
yet.
This commit ensures the user list is loaded after the constructor
finishes and the event loop runs irregardless of the accountsservice
state.

Right now we only show the session menu button when verifying,
but we should also show it when verification is failed or we
can end up in situation where the session menu disappears during
an authentication retry.
https://bugzilla.gnome.org/show_bug.cgi?id=707064
Right now, we rely on PAM to ask for the username if disable-user-list
is TRUE. This is suboptimal because it means we can't check if we
should show a session menu.
This commit changes disable-user-list==TRUE to ask for a username up
front, rather than have PAM do it.

commit 93f072d1fcf578c4e7550bd755e84bd46abcd493 attempted to
add support for auth without a username to the login screen, but
do to a messed up rebase only partially added it.
This commit fixes that.

This commit introduces a new BeginRequestType enum which gets
passed to the 'reset' signal to specify whether
a username should be provided to the begin() method and changes
the loginDialog to comply.
Currently, the signal only ever gets emitted with
AuthPrompt.BeginRequestType.PROVIDE_USERNAME
but that will change in the future when providing smartcard
support.
