Refactor FBConfig lookup Background: To bind a Xorg window content to a OpenGL FBConfig, which has to match the color format the Xorg window is using. Previously, compton just find a FBConfig that has the same depth. This led to chjj/compton#477, which has been fixed by a ugly hack. The commit refactor the lookup mechanism to take as much into consideration as we reasonably can. Hopefully preventing similar breakages in the future. Also, some code sharing between the old and new glx backend. Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com>

Condense GLX extension lookup Put them all into one function, and move the function pointers out of glx_session_t, making them global variables (because them don't change after initialized). Remove the function pointer typedefs and replace them with the ones in glxext.h We also only lookup the functions once per a lifetime of compton. Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com>

new glx: initial implementation This is basically just adapting old code to the new interface. A lot of the functions are still stubs, but the basic stuffs is working. What remains to be done: * Implement gl_image_op. (It should do the operation lazily, only update the flags on the texture. Actual processing will be delayed until composition.) * Implement gl_copy. Now it just return the same image after incrementing the refcount. It should actually copy the image data structure so it can have a separate set of flags.
