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.

The memory dealer introduces additional delays for reclaiming
the memory owned by CursorWindows because the Binder object must
be finalized. Using ashmem instead gives CursorWindow more
direct control over the lifetime of the shared memory region.
The provider now allocates the CursorWindows and returns them
to clients with a read-only protection bit set on the ashmem
region.
Improved the encapsulation of CursorWindow. Callers shouldn't
need to care about details like how string fields are allocated.
Removed the compile-time configuration of string and numeric
storage modes to remove some dead weight.

The code is functionally equivalent, but a little more efficient
and much easier to maintain.

let cursor window size be set per device in device resources file.
default is 1MB.
for SR, it is 2MB.
it can be set to any value (in kB) in the device resource
strings.xml file
