gallium: Add context profile support to st_api.
Add struct st_context_attribs to describe context profiles and attributes. Modify st_api::create_context to take the new struct instead of an st_visual. st_context_attribs can be used to support GLX_ARB_create_context_profile and GLX_EXT_create_context_es2_profile in the future. But the motivation for doing it now is to be able to replace ST_API_OPENGL_ES1 and ST_API_OPENGL_ES2 by profiles. Having 3 st_api's to provide OpenGL, OpenGL ES 1.1, and OpenGL ES 2.0 is not a sane abstraction, since all of them share glapi for current context/dispatch management.
