Ctrl+scrolling with a mouse wheel zoomed in the opposite direction
than expected: scrolling up zoomed out and scrolling down zoomed in,
which is inconsistent with other GNOME apps such as Loupe and
Nautilus.
Negate the scroll delta in both smooth (touchpad) and discrete
(mouse wheel) scrolling cases, so scrolling up now zooms in.

And, while at it, rewrite the layout algorithm to operate on blocks of
overlapping events, and segmented columns. Like the month view row,
layouts blocks are invalidated at any point in time, but recalculated
immediately before a relayout happens.
The reason for doing such a massive rewrite while in the middle of the
port to GListModel is because it's easier to handle GListModel data
with this approach, than with the previous approach of storing it all
in a GcalRangeTree.

The time direction property tells which orientation one
needs to scroll to change the time of the view. In these
directions (up/down v left/right) the new prev/next
buttons will be pointing.
The two buttons will be added in a subsequent commit,
and will gain view-dependent tooltips.

Now that we keep precise control over GcalEvent instances, and
can use simple pointer comparisons everywhere, GcalMonthView
implemented its update function as a simple remove + add pair.
The problem is that we're not passing the old event instance,
so removals never actually happen, since the new instance is
not yet available to subscribers.
Pass old event in additio to the new one, and use it where it
makes sense.

They behave slightly differently from smooth scroll events, and
they don't emit 'scroll-begin' nor 'scroll-end', so we have to
execute that the callbacks of these signals do inside the scroll
callback itself.
