Subject: [PATCH] libgui: improve some logging and dumping

This change updates some of the SurfaceTextureClient and BufferQueue logging
and dumping to include the crop, transform and scaling mode.  It also removes
the uses of the NO_SCALE_CROP scaling mode enum, which was added by accident in
a previous change.
