We were notifying when an unmount operation was performed. However,
creating notifications from the gtk+ library is not that expected, and
makes notification handling difficult to do from the application point
of view since we cannot dismiss those notifications.
This cause issues like notifications of unmount drives stay there after
a system reboot, which confuses the user.
Instead of that, remove the notification handling for mount operations
on gtk+ and instead create a new signal on the gtkplacessidebar in order
to inform applications using it about an operation about to start.
Only drawback about this is that the GtkFileChooser loses its
notifications when unmounting, that although we could use the new signal
to do it, we actually don't want to notify from any part of gtk+ for
now.

The following changes were done to (hopefully) achieve backwards
compatibility while allowing themes to change the size of the indicator.
(1) Deprecate the property.
(2) Change the default value of the property to 0. If it is not 0,
use the property's value for the indicator size. This should make
all programs that actually set it keep the size they set it to.
(3) If set to other values than 0, use min-width/min-height of the
check/radio node to size the indicator. This allows themes to change
the size.
(4) Fall back to the previous default size of 16px. This way themes that
do not set the size keep the same behavior.
...the sizing is still off, waiting for Benjamin to add the magic,
probably the icon shadow is missing, not sure since it's blurry.
This needs to be reverted in case the sizing won't get fixed.
We should conform to a minimal set of reasons for the gtk side to emit
a better GtkDragResult than GTK_DRAG_RESULT_ERROR. This fixes the notebook
tab DnD feature, where we rely on GTK_DRAG_RESULT_NO_TARGET.
In the wayland side, unfortunately we can't honor either NO_TARGET nor
USER_CANCELLED, we don't know of the latter, so we could return false
positives on the former.

Sometimes default tab labels ("Page <n>") get created on-demand,
and in that case, we were forgetting to put them below the tab
node in the CSS node tree. The visible result of this is that the
heuristics for when to give notebooks background in Adwaita fail
in some cases. So, make sure to always place the label below the
tab node.
Instead of drawing them as the background, use -gtk-icon-source.
Also size the marks properly.
Because Windows doesn't have indeterminate radio buttons, use a
cross-fade between checked and unchecked radiomark instead. But
unlike previously, use CSS cross-fade() syntax to draw it.
