mediafile: Turn into an extension point This way, we can support external libraries providing implementations of GtkMediaFile. We also add a media backend called 'nomedia' that can be enabled to not compile any support for GtkMediaFile. This is useful when people want to statically compile GTK into an application that does not use media. For now, this option is the default. We also support a new environment variable GTK_MEDIA that allows selecting the implementation to use. GTK_MEDIA=help can be used to get info about the available implementations.

media_subdir = 'gtk-4.0/@0@/media'.format(gtk_binary_version)
media_install_dir = join_paths(get_option('libdir'), media_subdir)
meson: Use feature options for media and print backends This gracefully disable ffmpeg, gstreamer, cups and cloudprint optional dependencies when they are not available, while still giving full control to distributors using -Dauto_features=enabled.

Revert "modules: Fix build on Visual Studio" This reverts commit acd9c12667a021936b30e0fa8f43d3a8c7133cf7. This commit breaks the build with GLib main on all platforms, and defining _GLIB_EXTERN arguably invades the GLib namespace. A different fix for msvc will have to be found.

modules/media/meson.build: Export needed symbols on MSVC We need to override _GLIB_EXTERN to export the required symbols for the GIO module on Visual Studio, so that the media modules can be successfully loaded.

gtkgstsink.c: Support EGL on Windows as well Add support to look for and use the EGL context in Windows if it was activated instead of desktop OpenGL. GstGL may have been built with or without EGL/libANGLE support, so if it were, check in GstGL whether we have gst_gl_display_new_with_type() to create a GstGLDisplay that is of the GST_GL_WINDOW_WIN32 type when we are using Desktop OpenGL (WGL), otherwise we show messages indicating that envvars need to be set to initialize GstGL properly. Due to a bug in GstGL, the GstGLContext can only be set up successfully if one of the following is true: * An OpenGL 3.x or later emulator, such as Mesa is used (for WGL) * The latest GstGL master is being used, at the time of writing (for WGL) * GTK, libepoxy and GstGL are all built only with WGL support (for WGL) * EGL is being used in GTK at runtime Special thanks to Matthew Waters for the help during the process.

meson: use correct module file extension on macOS GModule requires the .so file extension on macOS for historic reasons. However Meson defaults to .dylib for modules, so we need to override it to get the correct extension. Fixes #3645.
