gl_common: get rid of symbol redefinition warnings with recent Mesa Apparently newer Mesa versions changed their <GL/glx.h> header, and unconditionally define GLX_CONTEXT_MAJOR_VERSION_ARB and others. This clashed with gl_header_fixes.h, a header which quarantines bad hacks to make compilation possible on systems with outdated GL headers. Specifically, our header was included before glx.h, so the hacks were always active, and somehow Mesa's glx.h used to deal with this by not redefining existing identifiers. Fix the gl_header_fixes.h logic so the hacks are checked after including glx.h.

gl_common: allow compilation on Mac OS 10.6 Define just enough constants to allow compilation on OS X Snow Leopard. mpv's OpenGL autodetection features should make the rest.

#ifndef GL_NV_vdpau_interop
vo_opengl: support for vdpau hardware decoding This uses vdpau OpenGL interop to convert a vdpau surface to a texture. Note that this is a bit weak and primitive. Deinterlacing (or any other form of vdpau postprocessing) is not supported. vo_opengl chroma scaling and chroma sample position are not supported. Internally, the vdpau video surfaces are converted to a RGBA surface first, because using the video surfaces directly is too complicated. (These surfaces are always split into separate fields, and the vo_opengl core expects progressive frames or frames with weaved fields.)

vo_opengl: add some OpenGL standard symbols missing on OSX Older OSX versions are missing some OpenGL 3 symbols, apparently. At least there's some precedent in the headers. Just add the symbols manually for now to fix OSX (on travis-ci) compilation.

vo_opengl, x11: add ES context creation via GLX Apparently GLX can do this, so using EGL is not strictly required. This code tries to create an ES context if creating a desktop GL context fails. Also, a "x11es" backend for forcing ES (instead of desktop GL) is added, mostly for testing and debugging.
