Replace some leftover "android/database/" namespaces with "org/sqlite/database/". Make sure the native methods are all registered when the library is loaded. (check-in: b03c0713c9 user: dan tags: trunk)

Re-enable some disabled code required by user-defined function implementations. (check-in: e01e48cd52 user: dan tags: trunk)
16:04
Replace nativeExecuteForCursorWindow() with an implementation that builds with the NDK. Seems to work, but is not yet tested. Exception handling is almost certainly still wrong. (check-in: 365586dcaf user: dan tags: trunk)
