Each time we create a new window, we create a new EGLSurface. Each time
we destroy a window, we failed to destroy the EGLSurface, due to passing
a GdkDisplay instead of a EGLDisplay to eglDestroySurface().
This effectively leaked not only the EGL surface metadata, but also the
associated DMA buffers. For applications where one opens and closes many
windows over the lifetime of the application, and where the application
runs for a long time; for example a terminal emulator server, this
causes a significant memory leak, as the memory will only ever be freed
once once the application process itself exits, if ever.
Fix this passing an actual EGLDisplay instead of an GdkDisplay, to
eglDestroySurface().

When the pointer leaves the window surface, gtk_window_capture_motion
will not be called anymore, so priv->resize_cursor may remain non-NULL
indefinitely without this.
If update_cursor is later called (via gtk_window_maybe_update_cursor) on
a virtual enter notify event (e.g. because the pointer entered a
descendant surface), it would previously re-set the window surface
cursor to priv->resize_cursor, which could result in the wrong cursor
shape being shown for descendant surfaces.
This affected mutter-x11-frames, see
https://gitlab.freedesktop.org/xorg/xserver/-/issues/1557.
One could also say that if the pointer leaves the window surface, it's
trivially not over any window edge.

Avoids unaligned accesses when e.g. the key_size is 12 and key_align is
8. We need to round the key size up to 16 to ensure that all keys are
appropriately aligned.
This manifested as a failure in the `gtk:gtk / sorter` unit test on
sparc.

We want to always reserve space for the clear icon,
but let the text widget use that space when the icon
isn't shown. A plain box layout can't do that, so
do our own size allocation.
We may try to update the XRR outputs and Crtcs when they're changing in
the server, and so we may get BadRROutput that we're currently not
handling properly.
As per this, use traps and check whether we got errors, and if we did
let's ignore the current output.
It's not required to call init_randr13() again because if we got errors
it's very likely that there's a change coming that will be notified at
next iteration during which we'll repeat the init actions.
When registering an observer, we send a notification and for that we need
to query the action's state and param type. When setting up a muxer parent,
same thing happens, except the action is queried on the parent instead.
This means that the muxer will notify observers about the parent's actions,
but not about its own.
Add a test to verify it works.

The display xevent signal connection takes the ownership of the stream
until we get a valid event, so it should manage the stream lifetime.
So make this clearer, by automatically removing the stream reference
when we disconnect from the xevent signal handler.
We create a new stream during gdk_x11_selection_input_stream_new_async()
then such stream is referenced when passed to the task via
g_task_return_pointer(), so there's no need to reference it again before
returning it, or we'd end up leaking.
