The previous function gdk_drag_get_protocol_for_display() took native
window handles, so it had to be changed. Because it didn't do what it
was named to do (it didn't return a protocol even though it was named
get_protocol) and because it doesn't operate on the display anymore but
on the actual window, it's now called gdk_window_get_drag_protocol().
... and all APIs making use of it.
That code like it hasn't been touched in years, Google codesearch
didn't find any users and most importantly it's a horrendous API, so
let's just make it die instead of having to port it over to
non-GdkNativeWindow usage, which would be required for multi-backend
GDK.

There's no usecase for them, so remove them before we have to commit to
keeping an API.
Make the hooks private for now, actually removing them will come in
followup patches.
We want to have different window types for different displays, so we can
write code like this:
#if GDK_WINDOWING_X11
if (GDK_IS_X11_WINDOW (window))
{
/* do x11 stuff */
}
else
#endif
#if GDK_WINDOWING_WAYLAND
if (GDK_IS_WAYLAND_WINDOW (window))
{
/* do wayland stuff */
}
else
#endif
{
/* do stuff for unsupported system */
}
This requires different GdkWindow types and we currently don't have
that, as only the GdkWindowImpl differs. With this method, every backend
defines a custom type that's just a simple subclass of GdkWindow. This
way GdkWindow behaves like all the other types (visuals, screens,
displays) and we can write code like the above.
Move everything dealing with compound text to be X11 specific
Only gdk_text_property_to_utf8_list and gdk_utf8_to_string_target
are kept across backends, so add vfuncs for these.
Also, remove the non-multihead-safe variants of all these.
