We can't safely examine allocations synchronously using
gtk_main_iteration(), as there might be not enough time for a new paint
clock tick to have expired and the allocation set on the widget.
Work this around adding g_usleep() calls before processing pending
mainloop events.
When using GtkTreeStore, don't compute row positions assuming
everything's a list store, which is how get_row_start_for_index() works.
So instead, do a laxer check and don't insist on proper alignment.
It is just too annoying to have to implement these properties in
every scrollable. Instead, we now have ::min-content-height/width
in GtkScrolledWindow.
We also add GtkScrollablePolicy to determine how to size the
scrollable content.
The GtkScrollable interface provides "hadjustment" and "vadjustment"
properties that are used by GtkScrolledWindow. It replaces
the ::set_scroll_adjustment signal. The scrollable interface
also has ::min-display-width/height properties that can be
used to control the minimally visible part inside a scrolled window.
This test is constructed in such a way that it breaks when you
(currently!) do not trigger a size-request from validate_visible_area.
Especially row expansion appears to have a need for this currently.
The old version wasn't introspectable as it didn't have a length
return parameter. Also, delete gtk_tree_path_get_indices_with_depth,
since it's no longer needed.

Fix#477175, reported by Juri Pakaste.
* gtk/gtktreeprivate.h:
* gtk/gtktreeview.c (gtk_tree_view_top_row_to_dy): do not set
tree_view->priv->dy here directly, just calculate the new value
and set it on the adjustment,
(gtk_tree_view_adjustment_changed): add guards to not call
gtk_tree_view_dy_to_top_row() if we are currently in
gtk_tree_view_top_row_to_dy(),
(gtk_tree_view_put): fix coordinate annotation: these are bin_window
coordinates, not tree coordinates,
(gtk_tree_view_real_start_editing): add cast.
* gtk/tests/treeview-scrolling.c: add an assertion for checking the
position of the editable in the "create new row and start editing"
tests.
