gtk_entry_set_completion() (and _gtk_entry_completion_connect underneath)
may happen when the entry has no toplevel yet. This window acts as the
"parent" for subsurface windows on wayland, and is indispensable to create
its backing wl_subsurface, so this resulted in non-visible popups there.
Fix this by ensuring transient_for is set before showing the popup.

When using a completion with some custom cells in the cell layout,
if would often size wrong when first presented on screen.
The entry completion is the only place in the entire gtk code base
that calls gtk_tree_view_column_cell_get_size outside of gtktreeview
itself. It calls into the function before the tree view has done some
important validation on its cell state, the net result of which is
only the first element in the gtkcellareabox the entry completion uses
well actually have its size respected.
We now call gtk_widget_get_preferred_size on the tree view before
calling into the individual cell size routines, to guarantee that the
tree view has run its validate_rows routine and cell state is valid.

I tried asking but nobody knew why it is necessary to set the background
color of the first cell. It seems with CSS styling this is completely
unnecessary.
Using the setting for this property conflicts with the documentation
for gtk_entry_completion_set_text_column() which explicitly states
that setting the property directly behaves differently. Concretely,
this caused the file chooser entry completion popup to have two
columns (with identical content).
This partially reverts 331c28b369.
There are early returns in this method before the completion timeout
is set later on, so set the source to 0 to avoid trying to remove it
later again.

Call gtk_cell_layout_clear() on the area instead of the completion in
gtk_entry_completion_clear_text_column_renderer(), because it is also
called from within gtk_entry_completion_clear().
gtk_entry_completion_set_text_column() always added a cell renderer,
regardless of whether there was an existing one already installed. This
patch reuses an old renderer if it exists, but only if it was added by a
previous call to this function.
To avoid conflicts, all renderers that were added manually are removed
when calling this function. Also, the renderer added by this function is
removed when manually adding new renderers. This effectively gives
GtkEntryCompletion two modes (managed and manual cell renderers) and
allows seamless switching between the two.
This is a minor API break. However, this shouldn't be an issue in
practice as applications couldn't call set_text_column() more than once
because of this bug. Also, it is unlikely that many applications mix
set_text_column() and custom cell renderers. The interaction between the
two modes was erratic and not documented well.

Call gtk_entry_completion_set_text_column() when setting the
"text-column" property directly.
The completion appeared empty when setting "text-column" directly (for
example from a GtkBuilder file), because the setter creates and adds the
GtkCellRendererText.

We block signal handlers areound GtkEntry signal emission and if those
signals get used to call functions on the completion that cause a
reconnection of the signals, then the reconnected signals will not be
blocked anymore (so they might get emitted?) and unblocking the old
signal id will later cause warnings.
Fixes spurious warnings in gtk/tests/filechooser tests.
Also remove the starting underscore from function names where
appropriate, as those functions are static now and not exported anymore.
This is part of a bunch of fixes for gcc complaining about
-Wmissing-declarations.
This commit moves all the entry completion implementation
into gtkentrycompletion.c. It also gets rid of an unnecessary
completion_device member in GtkEntryPrivate.
