0ede9ebec7 Improvements to compile-time-option hygiene. Use "#if OPTION" instead of

the "HAVE_component" compile-time options.

grow to large, to avoid excess memory allocation resize operations.  Also,
document the fact that setting scratch memory causes SQLite to try to avoid
large memory allocations.
