vo_opengl: split utils.c/h Actually GL-specific parts go into gl_utils.c/h, the shader cache (gl_sc*) into shader_cache.c/h. No semantic changes of any kind, except that the VAO helper is made public again as part of gl_utils.c (all while the goal for gl_utils.c itself is to be included by GL-specific code).

vo_opengl: move shader handling to ra Now all GL-specifics of shader compilation are abstracted through ra. Of course we still have everything hardcoded to GLSL - that isn't going to change. Some things will probably change later - in particular, the way we pass uniforms and textures to the shader. Currently, there is a confusing mismatch between "primitive" uniforms like floats, and others like textures. Also, SSBOs are not abstracted yet.

vo_gpu: attempt to avoid UBOs for dynamic variables This makes the radeon driver shut up about frequently updating STATIC_DRAW UBOs (--opengl-debug), and also reduces the amount of synchronization necessary for vulkan uniform buffers. Also add some extra debugging/tracing code paths. I went with a flags-based approach in case we ever want to extend this.

vo_gpu: make the vertex attribs dynamic This has several advantages: 1. no more redundant texcoords when we don't need them 2. no more arbitrary limit on how many textures we can bind 3. (that extends to user shaders as well) 4. no more arbitrary limits on tscale radius To realize this, the VAO was moved from a hacky stateful approach (gl_sc_set_vertex_attribs) - which always bothered me since it was required for compute shaders as well even though they ignored it - to be a proper parameter of gl_sc_dispatch_draw, and internally plumbed into gl_sc_generate, which will make a (properly mangled) deep copy into params.vertex_attribs.

vo_gpu: handle texture initialization errors gracefully Tested by making the ra_tex_resize function always fail (apart from the initial FBO check). This required a few changes: 1. reset shaders on failed dispatch 2. reset cleanup binds on failed dispatch 3. fall back to initializing the struct image to 1x1 on failure 4. handle output_fbo_valid gracefully
