Surfaces are now destroyed properly in SurfaceFlinger.

First, the window manager tells us when a surface is no longer needed. At this point, several things happen:
- the surface is removed from the active/visible list
- it is added to a purgatory list, where it waits for all clients to release their reference
- it destroys all data/state that can be spared

Later, when all clients are done, the remains of the Surface are disposed off: it is removed from the purgatory and destroyed.
In particular its gralloc buffers are destroyed at that point (when we're sure nobody is using them anymore).
