vo_opengl: refactor into vo_gpu
This is done in several steps: 1. refactor MPGLContext -> struct ra_ctx 2. move GL-specific stuff in vo_opengl into opengl/context.c 3. generalize context creation to support other APIs, and add --gpu-api 4. rename all of the --opengl- options that are no longer opengl-specific 5. move all of the stuff from opengl/* that isn't GL-specific into gpu/ (note: opengl/gl_utils.h became opengl/utils.h) 6. rename vo_opengl to vo_gpu 7. to handle window screenshots, the short-term approach was to just add it to ra_swchain_fns. Long term (and for vulkan) this has to be moved to ra itself (and vo_gpu altered to compensate), but this was a stop-gap measure to prevent this commit from getting too big 8. move ra->fns->flush to ra_gl_ctx instead 9. some other minor changes that I've probably already forgotten Note: This is one half of a major refactor, the other half of which is provided by rossy's following commit. This commit enables support for all linux platforms, while his version enables support for all non-linux platforms. Note 2: vo_opengl_cb.c also re-uses ra_gl_ctx so it benefits from the --opengl- options like --opengl-early-flush, --opengl-finish etc. Should be a strict superset of the old functionality. Disclaimer: Since I have no way of compiling mpv on all platforms, some of these ports were done blindly. Specifically, the blind ports included context_mali_fbdev.c and context_rpi.c. Since they're both based on egl_helpers, the port should have gone smoothly without any major changes required. But if somebody complains about a compile error on those platforms (assuming anybody actually uses them), you know where to complain.

- OpenGL ES 2.0 and 3.0 are supported as well.
+ This VO abstracts over several possible graphics APIs and windowing
+ contexts, which can be influenced using the ``--gpu-api`` and
+ ``--gpu-context`` options.
Hardware decoding over OpenGL-interop is supported to some degree. Note
that in this mode, some corner case might not be gracefully handled, and
color space conversion and chroma upsampling is generally in the hand of
the hardware decoder APIs.
- ``opengl`` makes use of FBOs by default. Sometimes you can achieve better

+ ``gpu`` makes use of FBOs by default. Sometimes you can achieve better
+ quality or performance by changing the ``--gpu-fbo-format`` option to
``rgb16f``, ``rgb32f`` or ``rgb``. Known problems include Mesa/Intel not
accepting ``rgb16``, Mesa sometimes not being compiled with float texture
support, and some OS X setups being very slow with ``rgb16`` but fast
with ``rgb32f``. If you have problems, you can also try enabling the
- ``--opengl-dumb-mode=yes`` option.
