Overview
| Comment: | Add a dummy version (equivalent to BINARY) of collation sequence LOCALIZED to all new database handles. Now a simple "SELECT sqlite_version()" works. |

** This function is a collation sequence callback equivalent to the built-in

**
** Stock Android uses a modified version of sqlite3.c that calls out to a module
** named "sqlite3_android" to add extra built-in collations and functions to
** all database handles. Specifically, collation sequence "LOCALIZED". For now,
** this module does not include sqlite3_android (since it is difficult to build
** with the NDK only). Instead, this function is registered as "LOCALIZED" for all
** new database handles.
