mesa: call DrawBufferAllocate driver hook in update_framebuffer for windows-system FB
When draw buffers are changed on a bound framebuffer, DrawBufferAllocate() hook should be called. However, it is missing in update_framebuffer with window-system framebuffer, in which FB's draw buffer state should match context state, potentially resulting in a change. Note: This is needed because gallium delays creating the front buffer, i965 works fine without this change. V2 (Timothy Arceri): - Rebased on merged/simplified DrawBuffer driver function - Move DrawBuffer call outside fb->ColorDrawBuffer[0] != ctx->Color.DrawBuffer[0] check to make piglit pass. v3 (Timothy Arceri): - Call new DrawBuffaerAllocate() driver function.
