mesa: Make gl_vertex_array contain pointers to first order VAO members.

Browse Source 
Instead of keeping a copy of the vertex array content in
struct gl_vertex_array only keep pointers to the first order
information originaly in the VAO.
For that represent the current values by struct gl_array_attributes
and struct gl_vertex_buffer_binding.

v2: Change comments.
    Remove gl... prefix from variables except in the i965 directory where
    it was like that before. Reindent because of that.
