vo_opengl: x11egl: retrieve framebuffer depth This is used for dithering, although I'm not aware of anyone who got higher than 8 bit depth support to work on Linux. Also put this into egl_helpers.c. Since EGL is pseudo-portable at best I have no hope that the EGL context creation code in all the backends can be fully shared. But some self-contained functionality can definitely be shared.

Change GPL/LGPL dual-licensed files to LGPL Do this to make the license situation less confusing. This change should be of no consequence, since LGPL is compatible with GPL anyway, and making it LGPL-only does not restrict the use with GPL code. Additionally, the wording implies that this is allowed, and that we can just remove the GPL part.
