mesa: Rename ArrayObj to VAO and DefaultArrayObj to DefaultVAO.

When reading through the Mesa drawing code, it's not immediately obvious
to me that "ArrayObj" (gl_array_object) is the Vertex Array Object (VAO)
state.  The comment above the structure explains this, but readers still
have to remember this and translate accordingly.

Out of context, "array object" is a fairly vague.  Even in context,
"array" has a lot of meanings: glDrawArrays, vertex data stored in user
arrays, gl_client_arrays, gl_vertex_attrib_arrays, and so on.

Using the term "VAO" immediately associates these fields with the OpenGL
concept, clarifying the situation and aiding programmer sanity.

Completely generated by:
$ find . -type f -print0 | xargs -0 sed -i \
  -e 's/ArrayObj;/VAO;/g'                  \
  -e 's/->ArrayObj/->VAO/g'                \
  -e 's/Array\.ArrayObj/Array.VAO/g'       \
  -e 's/Array\.DefaultArrayObj/Array.DefaultVAO/g'
