/*
** This method has been rewritten for org.sqlite.database.*. The original 
** android implementation used the C++ interface to populate a CursorWindow
** object. Since the NDK does not export this interface, we invoke the Java
** interface using standard JNI methods to do the same thing.
**
** This function executes the SQLite statement object passed as the 4th 
** argument and copies one or more returned rows into the CursorWindow
** object passed as the 5th argument. The set of rows copied into the 
** CursorWindow is always contiguous.
**
** The only row that *must* be copied into the CursorWindow is row 
** iRowRequired. Ideally, all rows from iRowStart through to the end
** of the query are copied into the CursorWindow. If this is not possible
** (CursorWindow objects have a finite capacity), some compromise position
** is found (see comments embedded in the code below for details).
**
** The return value is a 64-bit integer calculated as follows:
**
**      (iStart << 32) | nRow
**
** where iStart is the index of the first row copied into the CursorWindow.
** If the countAllRows argument is true, nRow is the total number of rows
** returned by the query. Otherwise, nRow is one greater than the index of 
** the last row copied into the CursorWindow.
