Support for lookaside configuration params

Modified SQLiteDatabase to allow passing lookaside configuration to its
static initializer. Encapsulated config in OpenParams and added an
overloaded version of openDatabase with the new parameter.

Configuration is changed in SQLiteConnection::nativeOpen, immediately
after opening the database since lookaside memory configuration can only
be changed when no connection is using it.

Added SQLiteOpenHelper.setLookasideConfig method that is called from
the constructor of the subclass.
