Uli Schlachter 41a8fabf4c Explicitly track dependencies between widgets 
Before this, dependencies between widgets where implicitly discovered by
recursive calls to base.fit_widget() and base.layout_widget(). However, it is
too easy to get this wrong (just call one of these functions from outside of a
widget's :fit() / :layout() function) and the resulting mess would be hard to
debug.

Thus, this commit changes the API so that callers have to identify themselves
and we can explicitly record the dependency between the widgets involved.

This also fixes a bug where no dependencies were tracked for widgets after
:set_visible(false). Whoops...

Sorry for breaking the API for adding this.

Uli Schlachter 1ebc34b5e9 Widgets: Also add a context argument to :fit() 
Together with the context argument to :draw(), this even allows widgets to have
DPI-dependant size.

Uli Schlachter d990e7918f Use :weak_connect_signal() for connecting to widget::updated 
This way "that other widget" doesn't prevent the current widget from being
garbage collected.

Please note that this in all of these cases the widget under consideration does
have a strong reference to the callback function. This means that the callback
cannot be garbage collected until "this widget" itself is collected. Thanks to
this, this change is safe.
