vo_opengl: move hwdec parts into their own files This wasn't done before because there was no advantage in "abstracting" it. This changed, and putting this into its own files is better than messing it into gl_common.c/h.

client API: expose OpenGL renderer This adds API to libmpv that lets host applications use the mpv opengl renderer. This is a more flexible (and possibly more portable) option to foreign window embedding (via --wid). This assumes that methods like context sharing and multithreaded OpenGL rendering are infeasible, and that a way is needed to integrate it with an application that uses a single thread to render everything. Add an example that does this with QtQuick/qml. The example is relatively lazy, but still shows how relatively simple the integration is. The FBO indirection could probably be avoided, but would require more work (and would probably lead to worse QtQuick integration, because it would have to ignore transformations like rotation). Because this makes mpv directly use the host application's OpenGL context, there is no platform specific code involved in mpv, except for hw decoding interop. main.qml is derived from some Qt example. The following things are still missing: - a way to do better video timing - expose GL renderer options, allow changing them at runtime - support for color equalizer controls - support for screenshots

video: have a generic context struct for hwdec backends Before this commit, each hw backend had their own specific struct types for context, and some, like VDA, had none at all. Add a context struct (mp_hwdec_ctx) that provides a somewhat generic way to pass the hwdec context around. Some things get slightly better, some slightly more verbose. mp_hwdec_info is still around; it's still needed, but is reduced to its role of handling delayed loading of the hwdec backend.
