Creates a chooser managing a GDateTime. The chooser allows the user
to change the date, the time and the timezone independently.
This replaces the precedent GcalTimeChooserRow widget, because it is
easier to manage the different interactions with the user in a single
widget.

When dealing with floating time events the timezone used was UTC,
but according to RFC5545 when the timezone is not specified the
local timezone should be used.
Fixes#171
Timeline subscribers (i.e week_view, month_view, agenda_view, date_chooser) were not
properly notified of event(s) moved out of their listening ranges.
We notify them to remove these events.
fixes: #994 and #1043
This patch do not sends ADD_EVENT for events that are multiday and are
part of the old_range when calling calculate_changed_events. This will
prevent multiday duplicate events to appear in the agenda widget when
using the week view.
If the event is a multiday and it was in the previous range, it won't
send the REMOVE_EVENT so multiday events won't dissapear when it's still
relevant.

g_hash_table_lookup() is not transfer-full, so this g_autoptr + the
g_hash_table_remove() call end up double-unreffing the event, which
causes a crash.
Remove g_autoptr from the variable.
When removing the last subscriber (something that can happen when
closing the main window), GcalTimeline clears the event queue. But
that leaves us in an inconsistent state, as we don't process any of
the potentially removed events.
Don't do that.

Now that GcalTimeline properly notifies about the complete state,
it uncovered an issue where GcalShellSearchProvider was dereferencing
a NULL pointer.
Protect against that.
Don't try and track the number of completed calendars; instead,
recalculate the completed state from scratch every time. This
is not a performance concern, as we're dealing with at most some
hundreds of calendars.
The calendar view thread can start spinning its own mainloop
before g_thread_new() returns, and in that case we have a NULL
thread.
Check that either the GThread is what we expect it to be, OR,
the thread is NULL and there are no messages in the queue.
The notify signals of ESourceSelectable seem to come from the
ESourceRegistry thread, and this has the potential to derail
the execution of Calendar. This might be true for all signals
we connect to.
Make sure to always emit notify signals on the main thread.
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.

This should save quite some resources when manipulating events.
Signals are relatively expensive, and 2 pointer chases are
definitely better than a global lock + FFI stashing + signal
manipulation.
Apparently I never properly implemented range comparison in
remove_events_outside_range(). Do so now.
This makes the infinite scrolling month view stop flickering
events when changing weeks.
Instead of smashing the main thread's mainloop with
potentially hundreds or even thousands of idles that
add, remove, or update individual events, pass arrays
of events around.
When the until's time part is invalid, the libical claims the time
as valid, but the conversion into the GDateTime fails and returns NULL.
Such events, which claim to have until-date recurrence, but NULL 'until'
cannot be edited, because they cause a crash of the application.

When we receive the 'objects-modified' signal, we get components
that may represent main events. We also may receive components
that have no recurrency because they were just changed from being
recurrent to non-recurrent.
We need to handle all these cases properly.
If the event has no recurrency set, remove any potential old
recurrence instance lingering around. If we're changing an event
with recurrency, make sure the recurrency instances are in sync
with the new recurrency.

(or so I hope.)
We'll start accessing the hash table from multiple threads, so
it must be in the shared section of the structure, and it must
be encapsulated by locking.
