glx: Initialize OpenGL version to 1.0
The old code in dri2_glx suffered from a typographical error that caused the default version to be 2.1 instead of 1.2 (minimum required by the Linux OpenGL ABI). drisw_glx had a similar error resulting in a default version of 0.1. Some driver/card combinations (r200/RV280, i915/915G) don't support OpenGL 2.1. These create in some corner cases an indirect context instead of a direct context when calling glXCreateContextAttribsARB(). This happens because of a bad default value. To avoid this, just used the default value specified by the GLX_ARB_create_context specification: "The default values for GLX_CONTEXT_MAJOR_VERSION_ARB and GLX_CONTEXT_MINOR_VERSION_ARB are 1 and 0 respectively. In this case, implementations will typically return the most recent version of OpenGL they support which is backwards compatible with OpenGL 1.0 (e.g. 3.0, 3.1 + GL_ARB_compatibility, or 3.2 compatibility profile)" Refactor all the default value setting to dri2_convert_glx_attribs, and make sure the correct defaults are set in that one place.
