Deprecate local-only CursorWindows. 

There is no difference and has never really been a difference
between local-only and remotable CursorWindows.  By removing the
distinction officially in the API, we will make it easier to
implement CrossProcessCursor correctly.  CrossProcessCursor
is problematic currently because it's not clear whether a call
to getWindow() will return a local-only window or a remotable window.
As a result, the bulk cursor adaptor has special case handling
for AbstractWindowedCursors vs. ordinary CrossProcessCursors
so that it can set a remotable window before the cursor fills it.
All these problems go away if we just forget about local-only
windows being special in any way.
