    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.
