41ae93dba0 screenShield: Clear clipboard on lock
Currently the clipboard's contents may leak to unauthorized parties by
pasting into the unlock dialog's password entry and unmasking the entry.
Prevent this from happening by clearing the clipboard on lock.

61fe000daa ScreenShield: clear the lock screen early when deactivating
Upon popMode, MessageTray will try readding all notifications
to their rightful parent, so we must tell NotificationBox to
relinquish them before st_bin_set_child() fails (leaving a dangling
child pointer and crashing at the next allocation)

1ee88a2878 screenShield: Ensure we destroy background container widgets

ba198034cb screenShield: Remove blur and desaturation from lock screen
There's large performance issues with both the blur and desaturation
that make the screen shield hard to use on slower computers, and this
has always been a temporary stopgap until the user can pick a different
image for the lock screen.

4b3bf05aaf screenShield: Only release logind inhibitor on suspend
To make sure that the screen shield is shown before suspending, we
take a logind inhibitor and release it when the screen shield is
shown. As the screen shield is not only shown on suspend, we can end
up releasing the inhibitor independently from suspending (lock, idle),
in which case the screen might not be locked when we do suspend.
To fix, only release the inhibitor after showing the screen shield
when we are about to suspend.

d5e647a191 ScreenShield: fix positioning of background with multimonitor
Previously, we would create one StBin per monitor, but each was positioned
at 0,0 and sized as the screen, so they would overlap and draw the box shadows
on top of the other backgrounds.
Instead, we need to size appropriately the bin, and then we need to position
the actual MetaBacgroundActor at 0,0, so add a flag to BackgroundManager
for this.
Also, get rid of MetaBackgroundGroup, they do nothing because the screenshield
is not a descendant of the MetaWindowGroup and because the widget in between
blocks the propagation of the visible region. At the same time, use a
widget, not a bin, because StBin requires you to set .child, not call add_child().

b45a2d7335 ScreenShield: don't add the source actor directly to the boxlayout

4dc9540325 ScreenShield: try harder to become modal, and catch failures
The screenshield was not checking the return value of pushModal(), meaning
that it believed it was fully locked when it was not. Later, calling
popModal() would fail, causing an exception and blocking the unlock.
Now when we fail we include an explanatory message, pointing the user
to the actual cause of the issue.

a757ce48a1 ScreenShield: don't reset the lock screen animation if it's already happening
When you click Suspend from the user menu, the following things happen:
- we lock the screen internally by calling Main.screenShield.lock() and waiting
  for lock-screen-shown
- logind emits a Lock signal, which causes us to lock again
- gnome-settings-daemon notices PrepareForSleep, and calls org.gnome.ScreenSaver.Lock,
  just in case, so we lock once more
This means that, if you're lucky, you can see the curtain fall down multiple times,
as each .lock() call resets the animation.
