Jeff Brown 9d4e3d2f42 Banish DisplayID from the SurfaceFlinger API.
Use only display tokens in the API to refer to new displays.

Don't require the caller to specify the display when creating
a surface (since in general a surface could be shown on
any display).

This is intended to be a minimum change just to update the API.
Note that SurfaceFlinger still uses DisplayID in a few places
internally that might cause some features not to work properly
when there are multiple displays (LayerScreenshot, for example).
