Use ashmem for CursorWindows.
Bug: 5332296
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.

Clean up CursorWindow lifetime.
Bug: 5332296
Removed dead code in SQLiteCursor related to the use of a background
query thread. This code could result in CursorWindows being modified
concurrently or used after free. This code is broken, unused and
is just in the way.
Added comments to explain how CursorWindow ownership is
supposed to work for AbstractWindowedCursors. (There are still cases
where cursor windows get dropped on the floor without being closed.
Those will be taken care of in a subsequent patch.)
Cleaned up SQLiteQuery.fillWindow to eliminate duplicate code and
remove bits that were only needed for background loading, like
returning -1.

Clean up CursorWindow code.
Bug: 5332296
The code is functionally equivalent, but a little more efficient
and much easier to maintain.

fix bugs in exception throwing code in native_fillwindow
when exceptions are thrown, they are not being handled correctly
and the end result is some random errors/exceptions.
also change LOGD to LOGD_IF(cond,...) in keeping with Android
standards

Return count of rows in a resultset only once (when startPos = 0)
If a query returns 100 rows and say only 10 rows fit in 1MB, then client
receiving the cursor from the ContentProvider needs to paginate.
ContentProvider returns count of total data everytime it returns a page
(= 1MB) of data to the client.
Returning total count causes reading (and skipping unwanted) data
from sqlite.
Instead, it should be sufficient to get total count once
and re-use the count value during the life of the cursor
until a requery is performed on the cursor.
(Count won't change unless data is changed - in which case
the cursor is asked to perform requery anyway. So doing count
once and reusing it should work)
