Use a single compilation symbol We use a compilation symbol in our build to allow the inclusion of specific headers while building GTK, to avoid the need to include only the global header. Each namespace has its own compilation symbol because we used to have different libraries, and strict symbol visibility between libraries; now that we have a single library, and we can use private symbols across namespaces while building GTK, we should have a single compilation symbol, and simplify the build rules.

The big versioning cleanup Remove all the old 2.x and 3.x version annotations. GTK+ 4 is a new start, and from the perspective of a GTK+ 4 developer all these APIs have been around since the beginning.

GDK_AVAILABLE_IN_ALL
gdk: Move begin/end_frame() functions As they require a draw context and the draw context is already bound to the surface, it makes much more sense and reduces abiguity by moving these APIs to the draw context. As a side effect, we simplify GdkSurface APIs to a point where GdkSurface now does not concern itself with drawing anymore at all, apart from being the object that creates draw contexts.

GDK_AVAILABLE_IN_ALL
drawcontext: Add gdk_draw_context_in_frame() API This makes the previous gdk_draw_context_is_drawing() function public under a new name. I decided against the old name because we use the term "frame" for a drawing operation, so I wanted to have this boolean flag reuse the term.
