** The code in this file is used for testing SQLite. It is not part of
** the source code used in production systems.
**
** Specifically, this file tests the effect of errors while initializing
** the various pluggable sub-systems from within sqlite3_initialize().
** If an error occurs in sqlite3_initialize() the following should be
** true:
**
** 1) An error code is returned to the user, and
** 2) A subsequent call to sqlite3_shutdown() calls the shutdown method
** of those subsystems that were initialized, and
** 3) A subsequent call to sqlite3_initialize() attempts to initialize
** the remaining, uninitialized, subsystems.
