** Many people are failing to set -DNDEBUG=1 when compiling SQLite.
** Setting NDEBUG makes the code smaller and run faster. So the following
** lines are added to automatically set NDEBUG unless the -DSQLITE_DEBUG=1
** option is set. Thus NDEBUG becomes an opt-in rather than an opt-out
** NDEBUG and SQLITE_DEBUG are opposites. It should always be true that
** defined(NDEBUG)==!defined(SQLITE_DEBUG). If this is not currently true,
** make it true by defining or undefining NDEBUG.
**
** Setting NDEBUG makes the code smaller and run faster by disabling the
** number assert() statements in the code. So we want the default action
** to be for NDEBUG to be set and NDEBUG to be undefined only if SQLITE_DEBUG
** is set. Thus NDEBUG becomes an opt-in rather than an opt-out
** feature.
