Minor vertex array support tweaks. Most of these are in preparation for the

(eventual) addition of support for ARB_vertex_buffer_object.

Move all the private vertex array data structures out of
indirect_vertex_array.c and into indirect_va_private.h.

Rename array_state_vector::enabled_array_count to
array_state_vector::enabled_client_array_count.

Make sure that both the GL extension string and the server GL version are
available when __glXInitVertexState is called.

Make sure that array_state::normalized is set correctly in the array's
gl*Pointer function.
