5775738f67 plugin: Fix possible dir enumerator NULL unref
On an unlikely chance that sink was compiled without any importers, iterated dir does not exists thus we try to unref a NULL. Avoid doing that.

5b9e7eacba meson: Do not auto build rawimporter when building gluploader
No need to auto build rawimporter if we are building gluploader as it
will be always loaded on startup, but never used.

Skip the build of it when its meson option is set to "auto".

0410c6e9b5 plugin: Add GL uploader
Add "clappergluploader" module which uses "glupload" and "glcolorconvert" internally,
allowing either uploading RAW system memory into GPU with GL colorspace conversion or
importing DMABufs into GL memory and making a GdkTexture out of them at one go.

044710f97e plugin: Add clapper GStreamer plugin
Add new GStreamer plugin with custom video sink for Clapper video player.

The main difference is that unlike the old one, this does not operate using `GtkGLArea`
anymore, but processes and displays `GdkTextures` directly through `GtkPicture` widget.
Also this one is installed like any other GStreamer plugin, thus can be used via
`gst-launch-1.0` binary or even by other GTK4 apps if they wish to integrate it.

In order to not depend on GL stuff at build time, this plugin uses seperate GModules
called "importers" in order to import different kind of memories into GdkTexture. This
allows expanding its capabilities further then we were able to do before.
